TED, Alan Eustace: I leapt from the stratosphere. Here's how I did it (1)

Alan Eustace: I leapt from the stratosphere. Here's how I did it (1)

0:11So I grew up in Orlando, Florida. I was the son of an aerospace engineer. I lived and breathed the Apollo program. We either saw the launches from our backyard or we saw it by driving in the hour over to the Cape. I was impressed by, obviously, space and everything about it, but I was most impressed by the engineering that went into it.

0:33Behind me you see an amazing view, a picture that was taken from the International Space Station, and it shows a portion of our planet that's rarely seen and rarely studied and almost never explored. That place is called the stratosphere.

0:49If you start on the planet and you go up and up and up, it gets colder and colder and colder, until you reach the beginning of the stratosphere, and then an amazing thing happens. It gets colder at a much slower rate, and then it starts warming up, and then it gets warmer and warmer until the point where you can almost survive without any protection, about zero degrees, and then you end up getting colder and colder, and that's the top of the stratosphere. It is one of the least accessible places on our planet Most often, when it's visited, it's by astronauts who are blazing up at it at probably several times the speed of sound, and they get a few seconds on the way up, and then they get this blazing ball of fire coming back in, on the way back in.

1:40But the question I asked is, is it possible to linger in the stratosphere? Is it possible to experience the stratosphere? Is it possible to explore the stratosphere?

1:53I studied this using my favorite search engine for quite a while, about a year, and then I made a scary phone call. It was a reference from a friend of mine to call Taber MacCallum from Paragon Space Development Corporation, and I asked him the question: is it possible to build a system to go into the stratosphere? And he said it was. And after a period of about three years, we proceeded to do just that.And on October 24 of last year, in this suit, I started on the ground, I went up in a balloon to 135,890 feet -- but who's counting?

2:40(Laughter)

2:43Came back to Earth at speeds of up to 822 miles an hour. It was a four-minute and 27-second descent.And when I got to 10,000 feet, I opened a parachute and I landed.

2:57(Applause)

3:05But this is really a science talk, and it's really an engineering talk, and what was amazing to me about that experience is that Taber said, yes, I think we can build a stratospheric suit, and more than that, come down tomorrow and let's talk to the team that formed the core of the group that actually built it. And they did something which I think is important, which is they took the analogy of scuba diving. So in scuba diving, you have a self-contained system You have everything that you could ever need. You have a scuba tank. You have a wetsuit. You have visibility. And that scuba is exactly this system, and we're going to launch it into the stratosphere.

3:49Three years later, this is what we have. We've got an amazing suit that was made by ILC Dover. ILC Dover was the company that made all of the Apollo suits and all of the extravehicular activity suits. They had never sold a suit commercially, only to the government, but they sold one to me, which I am very grateful for. Up here we have a parachute This was all about safety. Everyone on the team knew that I have a wife and two small children -- 10 and 15 -- and I wanted to come back safely. So there's a main parachute and a reserve parachute, and if I do nothing, the reserve parachute is going to open because of an automatic opening device. The suit itself can protect me from the cold. This area in the front here has thermal protection. It will actually heat water that will wrap around my body. It has two redundant oxygen tanks. Even if I was to get a quarter-inch hole in this suit, which is extremely unlikely, this system would still protect me from the low pressure of space.

4:58The main advantage of this system is weight and complexity. So the system weighs about 500 pounds,and if you compare it to the other attempt recently to go up in the stratosphere, they used a capsule And to do a capsule, there's an amazing amount of complexity that goes into it, and it weighed about 3,000 pounds, and to raise 3,000 pounds to an altitude of 135,000 feet, which was my target altitude, it would have taken a balloon that was 45 to 50 million cubic feet. Because I only weighed 500 pounds in this system, we could do it with a balloon that was five times smaller than that, and that allowed us to use a launch system that was dramatically simpler than what needs to be done for a much larger balloon.

5:44So with that, I want to take you to Roswell, New Mexico, on October 24. We had an amazing team that got up in the middle of the night. And here's the suit. Again, this is using the front loader that you'll see in a second, and I want to play you a video of the actual launch. Roswell's a great place to launch balloons,but it's a fantastic place to land under a parachute, especially when you're going to land 70 miles away from the place you started. That's a helium truck in the background. It's darkness. I've already spent about an hour and a half pre-breathing And then here you see the suit going on. It takes about an hour to get the suit on. Astronauts get this really nice air-conditioned van to go to the launch pad, but I got a front loader.

6:34(Laughter)

6:37You can see the top. You can see the balloon up there. That's where the helium is. This is Dave clearing the airspace with the FAA for 15 miles. And there we go.

6:55(Laughter)

6:57That's me waving with my left hand. The reason I'm waving with my left hand is because on the right hand is the emergency cutaway

7:03(Laughter)

7:05My team forbade me from using my right hand. So the trip up is beautiful. It's kind of like Google Earth in reverse.

7:13(Laughter)

7:16It took two hours and seven minutes to go up, and it was the most peaceful two hours and seven minutes. I was mostly trying to relax. My heart rate was very low and I was trying not to use very much oxygen. You can see how the fields in the background are relatively big at this point, and you can see me going up and up.

7:37It's interesting here, because if you look, I'm right over the airport, and I'm probably at 50,000 feet, but immediately I'm about to go into a stratospheric wind of over 120 miles an hour. This is my flight director telling me that I had just gone higher than anybody else had ever gone in a balloon, and I was about 4,000 feet from release. This is what it looks like You can see the darkness of space, the curvature of the Earth, the fragile planet below. I'm practicing my emergency procedures mentally right now. If anything goes wrong, I want to be ready. And the main thing that I want to do here is to have a release and fall and stay completely stable.

8:34(Video) Ground control. Everyone ready? Five. Four. Three. Two. One

8:58Alan Eustace: There's the balloon going by, fully inflated at this point. And there you can see a drogue parachute, which I'll demonstrate in just a second, because that's really important. There's the balloon going by a second time. Right now, I'm about at the speed of sound. There's nothing for me to tell it's the speed of sound, and very soon I will actually be as fast as I ever get, 822 miles an hour.

9:48(Video) Ground control: We lost the data.

9:53AE: So now I'm down low right now and you can basically see the parachute come out right there. At this point, I'm very happy that there's a parachute out. I thought I was the only one happy, but it turns out mission control was really happy as well. The really nice thing about this is the moment I opened -- I had a close of friend of mine, Blikkies, my parachute guy He flew in another airplane, and he actually jumped out and landed right next to me. He was my wingman on the descent. This is my landing, but it's probably more properly called a crash.

10:29(Laughter)

10:34I hate to admit it, but this wasn't even close to my worst landing.

10:37(Laughter)

10:40(Applause)

10:59(Video) Man: How are you doing?

11:00AE: Hi there! Yay.

11:07(Laughter)

11:09So I want to tell you one thing that you might not have seen in that video, but one of the most critical parts of the entire thing was the release and what happens right after you release. And what we tried to do was use something called a drogue parachute, and a drogue parachute was there to stabilize me. And I'll show you one of those right now. If any of you have ever gone tandem skydiving, you probably used one of these. But the problem with one of these things is right when you release, you're in zero gravity. So it's very easy for this to just turn right around you. And before you know it, you can be tangled up or spinning, or you can release this drogue late, in which case what happens is you're going down at 800 miles an hour, and this thing is going to destroy itself and not be very useful. But the guys at United Parachute Technologies came up with this idea, and it was a roll that looks like that, but watch what happens when I pull it out. It's forming a pipe. This pipe is so solid that you can take this drogue parachute and wrap it around, and there's no way it will ever tangle with you. And that prevented a very serious potential problem.

12:30So nothing is possible without an amazing team of people. The core of this was about 20 people that worked on this for the three years, and they were incredible. People asked me what the best part of this whole thing was, and it was a chance to work with the best experts in meteorology and ballooning and parachute technology and environmental systems and high altitude medicine. It was fantastic It's an engineer's dream to work with that group of people. And I also at the same time wanted to thank my friends at Google, both for supporting me during this effort and also covering for me in the times that I was away. But there's one other group I wanted to thank, and that's my family. Yay.

13:12(Applause)

13:18I would constantly give them speeches about the safety of technology, and they weren't hearing any of it.It was super hard on them, and the only reason that my wife put up with it was because I came back incredibly happy after each of the 250 tests, and she didn't want to take that away from me. So I want to close with a story. My daughter Katelyn, my 15-year-old, she and I were in the car, and we were driving down the road, and she was sitting there, and she had this idea, and she goes, "Dad, I've got this idea. "And so I listened to her idea and I said, "Katelyn, that's impossible." And she looks at me and she goes, "Dad, after what you just did, how can you call anything impossible?" And I laughed, and I said, "OK, it's not impossible, it's just very, very hard

0:11So I grew up in Orlando, Florida. I was the son of an aerospace engineer. I lived and breathed the Apollo program. We either saw the launches from our backyard or we saw it by driving in the hour over to the Cape. O vimos los lanzamientos desde nuestro patio trasero o lo vimos conduciendo durante una hora hasta el Cabo. Мы либо видели катера со своего заднего двора, либо видели его, проехав через час до мыса. I was impressed by, obviously, space and everything about it, but I was most impressed by the engineering that went into it.

0:33Behind me you see an amazing view, a picture that was taken from the International Space Station, and it shows a portion of our planet that’s rarely seen and rarely studied and almost never explored. 0: 33 Detrás de mí, se ve una vista increíble, una imagen que se tomó de la Estación Espacial Internacional y muestra una parte de nuestro planeta que rara vez se ve y se estudia y casi nunca se explora. That place is called the stratosphere. Ese lugar se llama la estratosfera.

0:49If you start on the planet and you go up and up and up, it gets colder and colder and colder, until you reach the beginning of the stratosphere, and then an amazing thing happens. 0: 49Si empiezas en el planeta y subes y subes, se vuelve más y más frío, hasta que alcanzas el comienzo de la estratosfera, y entonces sucede algo asombroso. It gets colder at a much slower rate, and then it starts warming up, and then it gets warmer and warmer until the point where you can almost survive without any protection, about zero degrees, and then you end up getting colder and colder, and that’s the top of the stratosphere. Se enfría a un ritmo mucho más lento, y luego comienza a calentarse, y luego se calienta más y más hasta el punto en que casi puedes sobrevivir sin ningún tipo de protección, aproximadamente cero grados, y luego terminas cada vez más frío y más frío, y Esa es la cima de la estratosfera. It is one of the least accessible places on our planet Most often, when it’s visited, it’s by astronauts who are blazing up at it at probably several times the speed of sound, and they get a few seconds on the way up, and then they get this blazing ball of fire coming back in, on the way back in. Es uno de los lugares menos accesibles de nuestro planeta. La mayoría de las veces, cuando es visitada, es por los astronautas que están ardiendo en ella, probablemente varias veces la velocidad del sonido, y consiguen unos segundos en el camino, y luego consigue que esta ardiente bola de fuego regrese, en el camino de regreso. C'est l'un des endroits les moins accessibles de notre planète. faire revenir cette boule de feu flamboyante, sur le chemin du retour. Это одно из наименее доступных мест на нашей планете. Чаще всего его посещают астронавты, которые летят туда со скоростью, наверное, в несколько раз превышающей скорость звука, и у них есть несколько секунд на подъем, а потом они вернуть этот пылающий огненный шар обратно, на обратном пути.

1:40But the question I asked is, is it possible to linger in the stratosphere? 1: 40Pero la pregunta que hice es: ¿es posible permanecer en la estratosfera? 1: 40Mais la question que j'ai posée est la suivante: est-il possible de s'attarder dans la stratosphère? Is it possible to experience the stratosphere? Is it possible to explore the stratosphere?

1:53I studied this using my favorite search engine for quite a while, about a year, and then I made a scary phone call. 1: 53 Estudié esto usando mi motor de búsqueda favorito durante bastante tiempo, aproximadamente un año, y luego hice una llamada de miedo. It was a reference from a friend of mine to call Taber MacCallum from Paragon Space Development Corporation, and I asked him the question: is it possible to build a system to go into the stratosphere? And he said it was. Y él dijo que era. And after a period of about three years, we proceeded to do just that.And on October 24 of last year, in this suit, I started on the ground, I went up in a balloon to 135,890 feet -- but who’s counting? Y después de un período de aproximadamente tres años, procedimos a hacer justamente eso. Y el 24 de octubre del año pasado, en este traje, empecé en el suelo, subí en un globo a 135,890 pies, pero ¿quién está contando?

2:40(Laughter)

2:43Came back to Earth at speeds of up to 822 miles an hour. It was a four-minute and 27-second descent.And when I got to 10,000 feet, I opened a parachute and I landed.

2:57(Applause)

3:05But this is really a science talk, and it’s really an engineering talk, and what was amazing to me about that experience is that Taber said, yes, I think we can build a stratospheric suit, and more than that, come down tomorrow and let’s talk to the team that formed the core of the group that actually built it. 3: 05 Pero esta es realmente una charla de ciencia, y es realmente una charla de ingeniería, y lo que me sorprendió de esa experiencia es que Taber dijo, sí, creo que podemos construir un traje estratosférico, y más que eso, venir mañana y hablemos con el equipo que formó el núcleo del grupo que realmente lo construyó. And they did something which I think is important, which is they took the analogy of scuba diving. So in scuba diving, you have a self-contained system You have everything that you could ever need. Así que en el buceo, usted tiene un sistema autónomo. Tiene todo lo que pueda necesitar. You have a scuba tank. You have a wetsuit. Je hebt een wetsuit. You have visibility. And that scuba is exactly this system, and we’re going to launch it into the stratosphere. Y ese buceo es exactamente este sistema, y lo lanzaremos a la estratosfera.

3:49Three years later, this is what we have. We’ve got an amazing suit that was made by ILC Dover. Nous avons un costume incroyable qui a été fabriqué par ILC Dover. ILC Dover was the company that made all of the Apollo suits and all of the extravehicular activity suits. ILC Dover was het bedrijf dat alle Apollo-pakken en alle extravehiculaire activiteitenpakken maakte. They had never sold a suit commercially, only to the government, but they sold one to me, which I am very grateful for. Up here we have a parachute This was all about safety. Everyone on the team knew that I have a wife and two small children -- 10 and 15 -- and I wanted to come back safely. So there’s a main parachute and a reserve parachute, and if I do nothing, the reserve parachute is going to open because of an automatic opening device. Así que hay un paracaídas principal y un paracaídas de reserva, y si no hago nada, el paracaídas de reserva se abrirá debido a un dispositivo de apertura automático. The suit itself can protect me from the cold. This area in the front here has thermal protection. It will actually heat water that will wrap around my body. It has two redundant oxygen tanks. Even if I was to get a quarter-inch hole in this suit, which is extremely unlikely, this system would still protect me from the low pressure of space. Incluso si tuviera un agujero de un cuarto de pulgada en este traje, lo cual es extremadamente improbable, este sistema aún me protegerá de la baja presión del espacio.

4:58The main advantage of this system is weight and complexity. 4: 58La principal ventaja de este sistema es el peso y la complejidad. 4:58Главное преимущество этой системы — вес и сложность. So the system weighs about 500 pounds,and if you compare it to the other attempt recently to go up in the stratosphere, they used a capsule And to do a capsule, there’s an amazing amount of complexity that goes into it, and it weighed about 3,000 pounds, and to raise 3,000 pounds to an altitude of 135,000 feet, which was my target altitude, it would have taken a balloon that was 45 to 50 million cubic feet. Así que el sistema pesa alrededor de 500 libras, y si lo comparas con el otro intento reciente de subir en la estratosfera, utilizaron una cápsula. Y para hacer una cápsula, hay una increíble complejidad que entraña, y pesó aproximadamente 3,000 libras, y para elevar 3,000 libras a una altitud de 135,000 pies, que era mi altitud objetivo, habría tomado un globo que era de 45 a 50 millones de pies cúbicos. Because I only weighed 500 pounds in this system, we could do it with a balloon that was five times smaller than that, and that allowed us to use a launch system that was dramatically simpler than what needs to be done for a much larger balloon. Debido a que solo pesaba 500 libras en este sistema, podríamos hacerlo con un globo cinco veces más pequeño que eso, y eso nos permitió usar un sistema de lanzamiento que era mucho más simple de lo que se necesita hacer para un globo mucho más grande.

5:44So with that, I want to take you to Roswell, New Mexico, on October 24. 5: 44Así que con eso, quiero llevarte a Roswell, Nuevo México, el 24 de octubre. We had an amazing team that got up in the middle of the night. У нас была замечательная команда, которая встала посреди ночи. And here’s the suit. Again, this is using the front loader that you’ll see in a second, and I want to play you a video of the actual launch. Nuevamente, esto está usando el cargador frontal que verás en un segundo, y quiero reproducirte un video del lanzamiento real. Roswell’s a great place to launch balloons,but it’s a fantastic place to land under a parachute, especially when you’re going to land 70 miles away from the place you started. That’s a helium truck in the background. Eso es un camión de helio en el fondo. It’s darkness. I’ve already spent about an hour and a half pre-breathing And then here you see the suit going on. Ya he pasado alrededor de una hora y media antes de la respiración. Y aquí ves que el traje sigue adelante. It takes about an hour to get the suit on. Astronauts get this really nice air-conditioned van to go to the launch pad, but I got a front loader. Les astronautes obtiennent cette très belle camionnette climatisée pour se rendre à la rampe de lancement, mais j'ai un chargeur frontal.

6:34(Laughter)

6:37You can see the top. You can see the balloon up there. That’s where the helium is. This is Dave clearing the airspace with the FAA for 15 miles. Este es Dave limpiando el espacio aéreo con la FAA por 15 millas. C'est Dave qui nettoie l'espace aérien avec la FAA sur 15 miles. And there we go.

6:55(Laughter)

6:57That’s me waving with my left hand. 6: 57Eso soy yo saludando con la mano izquierda. The reason I’m waving with my left hand is because on the right hand is the emergency cutaway La razón por la que estoy saludando con la mano izquierda es porque en la mano derecha está el corte de emergencia La raison pour laquelle j'agite avec ma main gauche est que sur la main droite se trouve la coupe d'urgence De reden dat ik met mijn linkerhand zwaai, is omdat aan de rechterkant de noodopening is

7:03(Laughter)

7:05My team forbade me from using my right hand. So the trip up is beautiful. Así que el viaje es hermoso. Так что поездка наверх прекрасна. It’s kind of like Google Earth in reverse. Это похоже на Google Earth наоборот.

7:13(Laughter)

7:16It took two hours and seven minutes to go up, and it was the most peaceful two hours and seven minutes. I was mostly trying to relax. En su mayoría estaba tratando de relajarme. My heart rate was very low and I was trying not to use very much oxygen. Mi ritmo cardíaco era muy bajo y estaba tratando de no usar mucho oxígeno. You can see how the fields in the background are relatively big at this point, and you can see me going up and up. Puedes ver cómo los campos en el fondo son relativamente grandes en este punto, y puedes verme subir y subir.

7:37It’s interesting here, because if you look, I’m right over the airport, and I’m probably at 50,000 feet, but immediately I’m about to go into a stratospheric wind of over 120 miles an hour. This is my flight director telling me that I had just gone higher than anybody else had ever gone in a balloon, and I was about 4,000 feet from release. Este es el director de vuelo que me dice que acababa de llegar más alto que cualquier otra persona que había ido en globo, y que estaba a unos 4.000 pies de la liberación. This is what it looks like You can see the darkness of space, the curvature of the Earth, the fragile planet below. Voici à quoi cela ressemble Vous pouvez voir l'obscurité de l'espace, la courbure de la Terre, la planète fragile en dessous. I’m practicing my emergency procedures mentally right now. If anything goes wrong, I want to be ready. And the main thing that I want to do here is to have a release and fall and stay completely stable. И главное, что я хочу здесь сделать, это чтобы релиз упал и остался полностью стабильным.

8:34(Video) Ground control. Everyone ready? Five. Four. Three. Two. One

8:58Alan Eustace: There’s the balloon going by, fully inflated at this point. And there you can see a drogue parachute, which I’ll demonstrate in just a second, because that’s really important. Y allí puedes ver un paracaídas drogue, que demostraré en un segundo, porque eso es muy importante. Et là, vous pouvez voir un parachute de drogue, que je vais démontrer dans une seconde, car c'est vraiment important. En daar kun je een drogue-parachute zien, die ik zo dadelijk zal demonstreren, want dat is echt belangrijk. There’s the balloon going by a second time. Right now, I’m about at the speed of sound. There’s nothing for me to tell it’s the speed of sound, and very soon I will actually be as fast as I ever get, 822 miles an hour.

9:48(Video) Ground control: We lost the data.

9:53AE: So now I’m down low right now and you can basically see the parachute come out right there. At this point, I’m very happy that there’s a parachute out. I thought I was the only one happy, but it turns out mission control was really happy as well. The really nice thing about this is the moment I opened -- I had a close of friend of mine, Blikkies, my parachute guy He flew in another airplane, and he actually jumped out and landed right next to me. Lo realmente bueno de esto es el momento en que abrí. Tuve un amigo mío, Blikkies, mi tipo de paracaídas. Voló en otro avión y, de hecho, saltó y aterrizó justo a mi lado. He was my wingman on the descent. Él era mi compañero de ala en el descenso. Hij was mijn wingman tijdens de afdaling. This is my landing, but it’s probably more properly called a crash. Este es mi aterrizaje, pero es más probable que se llame un choque.

10:29(Laughter)

10:34I hate to admit it, but this wasn’t even close to my worst landing. 10: 34 Odio admitirlo, pero esto no fue ni siquiera cerca de mi peor aterrizaje.

10:37(Laughter)

10:40(Applause)

10:59(Video) Man: How are you doing?

11:00AE: Hi there! Yay.

11:07(Laughter)

11:09So I want to tell you one thing that you might not have seen in that video, but one of the most critical parts of the entire thing was the release and what happens right after you release. And what we tried to do was use something called a drogue parachute, and a drogue parachute was there to stabilize me. And I’ll show you one of those right now. If any of you have ever gone tandem skydiving, you probably used one of these. Si alguno de ustedes alguna vez ha realizado paracaidismo en tándem, probablemente usó uno de estos. But the problem with one of these things is right when you release, you’re in zero gravity. So it’s very easy for this to just turn right around you. Así que es muy fácil para esto simplemente girar a tu alrededor. Так что это очень легко просто повернуть направо вокруг вас. And before you know it, you can be tangled up or spinning, or you can release this drogue late, in which case what happens is you’re going down at 800 miles an hour, and this thing is going to destroy itself and not be very useful. Y antes de que se dé cuenta, puede estar enredado o girando, o puede soltar este drogue tarde, en cuyo caso lo que pasa es que está bajando a 800 millas por hora, y esta cosa se destruirá y no se destruirá. muy útil. But the guys at United Parachute Technologies came up with this idea, and it was a roll that looks like that, but watch what happens when I pull it out. Pero a los chicos de United Parachute Technologies se les ocurrió esta idea, y era un rollo que se ve así, pero mira lo que pasa cuando lo saco. It’s forming a pipe. Se está formando una tubería. This pipe is so solid that you can take this drogue parachute and wrap it around, and there’s no way it will ever tangle with you. Cette pipe est si solide que vous pouvez prendre ce parachute de drogue et l'enrouler, et il est impossible qu'il s'emmêle jamais avec vous. And that prevented a very serious potential problem.

12:30So nothing is possible without an amazing team of people. The core of this was about 20 people that worked on this for the three years, and they were incredible. People asked me what the best part of this whole thing was, and it was a chance to work with the best experts in meteorology and ballooning and parachute technology and environmental systems and high altitude medicine. La gente me preguntó cuál era la mejor parte de todo esto, y fue una oportunidad de trabajar con los mejores expertos en meteorología y tecnología de globos aerostáticos y paracaídas y sistemas ambientales y medicina de gran altitud. Les gens m'ont demandé quelle était la meilleure partie de tout cela, et c'était une chance de travailler avec les meilleurs experts en météorologie, en technologie des montgolfières et des parachutistes, des systèmes environnementaux et de la médecine de haute altitude. It was fantastic It’s an engineer’s dream to work with that group of people. And I also at the same time wanted to thank my friends at Google, both for supporting me during this effort and also covering for me in the times that I was away. Y también, al mismo tiempo, quería agradecer a mis amigos de Google, tanto por apoyarme en este esfuerzo como por cubrirme en los momentos en que estaba ausente. But there’s one other group I wanted to thank, and that’s my family. Yay.

13:12(Applause)

13:18I would constantly give them speeches about the safety of technology, and they weren’t hearing any of it.It was super hard on them, and the only reason that my wife put up with it was because I came back incredibly happy after each of the 250 tests, and she didn’t want to take that away from me. 13: 18 Les daría discursos constantemente sobre la seguridad de la tecnología, y no escucharon nada de eso. Fue muy duro para ellos, y la única razón por la que mi esposa lo soportó fue porque regresé increíblemente feliz después de cada una de las 250 pruebas, y ella no quería quitarme eso. So I want to close with a story. My daughter Katelyn, my 15-year-old, she and I were in the car, and we were driving down the road, and she was sitting there, and she had this idea, and she goes, "Dad, I’ve got this idea.
