"Grissom will have greater control over the flight of his spacecraft and a new explosive escape hatch." "Grissom names his capsule Liberty Bell 7." "It has another important, new feature." "GLENN:" "In the original spacecraft design, there was no window." "The reason was that that was gonna add weight -- not only the window itself, which had to be thick, but the support structure around it." "And weight was critical."

"Gus was sitting there minding his own business, and, all at once, it was pow." "The hatch blew, and water started coming in over the side." "NARRATOR:" "The capsule starts sinking." "Grissom has only moments to escape." "The space suit is designed to keep him afloat." "He had forgot to close one of the valves in his suit, and it was letting water in."

"He was very close to drowning." "NARRATOR:" "Unaware Gus is in trouble, helicopter pilot Jim Lewis tries to save the sinking capsule first." "LEWIS:" "We almost had it free and out, but every time it came out, a wave would come along and grab it and pull it back down." "KRANZ:" "In Mission Control, we were absolutely helpless." "We were watching the helicopter trying to grapple and lift the spacecraft up." "And we could see Gus struggling out there in the rotor wash." "And in Mission Control, a lot of us were saying, "Forget the spacecraft!" "Get Gus, get Gus, get Gus!"" "NARRATOR:" "Suddenly, Lewis has another problem."

"After more than a month of delays, he's finally ready to fly." "KRANZ:" "We lived in a motel about 15 miles south of the space center." "And every morning when we'd get ready to come out to work, we'd go and look and see if the searchlights were on on the launchpad." "If the searchlights were on, we felt pretty confident driving in, because somebody was there doing something and the countdown was more than likely progressing." "You felt, "Okay, we're going for it." "We're gonna get it today."" "NARRATOR:" "NASA needs more power to put a spacecraft into orbit." "The larger Atlas rocket will blast Glenn 162 miles above the Earth at a speed of 17,500 miles an hour." "BARBREE:" "John Glenn -- He was a fighter pilot in world War II and Korea."

"Someone had predicted that, in zero G, your eyes no longer needed to be supported by the structure under the eye and that your eye would gradually change shape in orbit." "Your eye might change enough, you would have trouble seeing the instrument panel." "NARRATOR:" "NASA has tracking stations all over the world." "KRAFT:" "We had the capability to track spacecraft by radar, and we had the capability of getting EKG and heart rate and breath rate, as well as telling us what was going on in the spacecraft."

"GLENN:" "I'd been through all of that -- 11 scheduled dates and three times up there." "So, when it finally came, it was almost a surprise to go." "When you're out there and you're actually on the launchpad, there's no way to simulate that." "MAN:" "Your attention, please." "On my mark, we will pick up the count." "NARRATOR:" "More than 50,000 people watched from nearby Cocoa Beach." "We reporters would watch from the beaches then, because they wouldn't let us in." "But we kept banging at the gates and kicking at the fences." "They said, "They're more of a nuisance outside than they'll be on the inside," so they finally let us in." "It was just the greatest place in the world." "NARRATOR: 100 million people across America watched the countdown live on television." "MAN:" "T-Minus 15 minutes." "Mark." "GLENN:" "When it came time to go, the whole world was with me." "MAN:" "All recorders to fast T-Minus 18 seconds and counting." "I was the communicator for the countdown." "I wanted to say something like, "Bon voyage, buddy." "Have a good time."" "And also enlist the aid of our maker in protecting him."

"BARBREE:" "And the excitement of John Glenn going into orbit " "This was the adventure of the 20th century." "MAN:" "The moment when the final Atlas engine will shut down, when Friendship 7 should separate from the booster rocket and begin orbital flight." "GLENN:" "After all the dire predictions of what might happen and how you might feel in space in zero G, and there wasn't any problem at all." "Of course, in the Mercury spacecraft, there wasn't anyplace to float to." "You were just in there." "You're in a cockpit and strapped in." "The most you could do would be loosen the straps to be a little more comfortable." "But it was an elated feeling of zero G and seeing how things work and seeing whether you could swallow." "Nothing prepares you for the view as you look outside." "You can see the curvature of the Earth's surface and whole nations just at a glance." "NARRATOR:" "As Glenn orbits the Earth," "Mission Control follows him from one tracking station to the next." "LUNNEY:" "I was at a tracking station in Bermuda, and the tracking from the Cape was beginning to get very marginal as the vehicle sunk down, going over the horizon." "And the tracking from Bermuda was becoming an increasingly better location to measure the fact that we were in orbit." "It was fun." "It was demanding, but it was fun." "We really enjoyed ourselves." "KRAFT:" "Everything was going so well that it was beyond belief that it could go that easily." "NARRATOR:" "But as Glenn completes his first orbit," "Mission Control confronts its first crisis in space." "The telemetry people noticed a signal which was indicating that the heat shield had come loose." "It was very scary to me." "If indeed the heat shield was loose, during reentry, the spacecraft would probably get very hot -- temperatures of 3,000 degrees." "The heat might burn off the heat shield, and it would have killed him." "We ran a few tests to see if what we were seeing was correct." "We began to ask him questions." "GLENN:" "Do I feel any bumping or something like that?" "So it's quite obvious they weren't telling me exactly what they were thinking on the ground." "NARRATOR:" "If the problem is real, the straps for the retro-rockets are the only thing holding the heat shield in place." "CARPENTER:" "John didn't like not being told what was wrong with the machine that he was flying." "KRAFT:" "The reason we didn't was because there wasn't anything he could do about it." "GLENN:" "I think the astronaut needs to know everything they know on the ground." "If you lost communications, the astronaut should have all the information." "NARRATOR:" "The engineers quietly hope the straps hold until the capsule hits denser air." "Then the force of descent should keep the heat shield in place." "GLENN:" "But when I first started reentry and the retro-rockets fired, the straps that held that retropack onto the basic spacecraft itself burned off." "There were burning chunks coming back by the window." "Sort of a thump on the spacecraft." "NARRATOR:" "During reentry, ionized plasma builds up around the spacecraft, causing a radio blackout for about three minutes." "The world waits to hear if John Glenn is dead or alive." "The heat shield was not loose." "It was a microswitch malfunction." "NARRATOR:" "With Glenn's orbital flight, the U.S. finally catches up to the Soviet Union." "John Glenn instantly becomes one of America's greatest heroes." "GLENN:" "We had been concentrated so much on this mission for so long, just didn't think much about anything else." "And then to have it over was really a big relief." "[ Cheers and Applause ]" "CARPENTER:" "After John's flight, we were all proud." "I was proud of him." "We were all proud of the United States for doing it." "[ Cheers and Applause ]" "KRAFT:" "It was proof positive that this country could compete in the world of space flight and that the Russians, indeed, were not ahead of us." "PRESIDENT KENNEDY:" "Some months ago, I said that I hoped that every American would serve his country." "Today Colonel Glenn served his, and we all express our thanks to him." "We have a long way to go in the space race, but this is the new ocean, and I believe the United States must sail on it and be in a position second to none." "NARRATOR:" "The U.S. is on track to fulfill Kennedy's dream, yet orbital flight is just one small step." "Now NASA must begin to explore the hostile territory of space." "GLENN:" "The reason you're going up there is not just to see if you can do it." "It's to do basic research." "NARRATOR:" "In his capsule, Aurora 7," "Scott Carpenter will fly next." "CARPENTER:" "John's flight was an experimental test flight." "Mine was to be more of a scientific investigation." "There were visibility experiments." "There were capsule-maneuvering tasks that were new." "It was a very busy flight plan." "MAN:" "Your attention, please." "all personnel, please clear the test-stand area to the roadblock." "NARRATOR:" "Aurora 7 blasts off for three orbits of the Earth -- nearly five hours in space." "MAN:" "5... 4 ...3 ...2 ... 1... 0 ." "Ignition." "Scott Carpenter -- I call him a romanticist." "He was interested in the beauty of space -- the sunrise and the sunset." "MAN:" "Roger." "CARPENTER:" "I remember just spinning a camera a little and letting it go and watch it stay right there." "That's an amazing sight -- the view and the weightlessness." "Things do look different." "The stars don't twinkle anymore." "There's no atmosphere." "It's an addictive sight." "He was distracted many times during the flight." "NARRATOR:" "For the first time, conflicts arise between the astronaut and Mission Control." "He kept using the fuel in a cavalier fashion." "He was maneuvering the spacecraft to look here, there, and everywhere at sights that he wanted to see." "Frankly, I can understand that." "There was a requirement for me to expend more fuel because of the observations I wanted to make." "KRAFT:" "During the first revolution, he used up the fuel in the automatic control system almost completely." "We told him to stop using that system." "He got to the manual system and used up all but about 10% or 20% of the manual fuel." "NARRATOR:" "Scott Carpenter is running out of gas." "KRAFT:" "When he came up on retrofire, the fuel had been almost entirely depleted." "CARPENTER:" "I didn't have any fuel." "The thrusters were not working." "NARRATOR:" "For reentry, Carpenter has to manually turn the capsule 180 degrees so the heat shield faces down." "But he has another problem." "An automatic attitude sensor, used to align the capsule, is off by nearly 40 degrees..." "and only Carpenter knows it." "He did not tell us that, and we had no way of knowing on the ground there was this bias there." "NARRATOR:" "Now he's got to fire the retro-rockets manually." "CARPENTER:" "Roger." "NARRATOR:" "With a faulty sensor, Carpenter's already off-target." "If he's not positioned perfectly, the heat shield down, the capsule will burn up."
