...planned impact point was 200 miles east of Bermuda, where an array of ships and aircraft waited anxiously. Down curved MA-4, trailing flames, its simulated astronaut stoically suffering 7.8 Gs of deceleration. The tough 6-ft. drogue chute opened first; then the main chute opened and lowered MA4 gently into the Atlantic, 161 miles east of Bermuda and only 39 miles off target. For a vehicle that had been traveling at 17,519 m.p.h., this was good shooting indeed. Aircraft spotted the capsule at once, and the destroyer Decatur raced to pick...
...Grissom's craft began to push against the top of the atmosphere, the Gs rose-to ten, then to a fearful 10.2-and communication dimmed a little, but never wholly stopped. Grissom reported clearly at 65,000 ft. that the Gs were much lower now. Then, with the capsule at 40,000 ft., the men on the Randolph and the choppers strained to catch their first glimpse of it. Automatically the small, tough drogue parachute opened at 21,000 ft., checking the capsule's falling speed. One minute later, the great, striped, red-and-white main parachute (with...
...rocket climbed, Shepard calmly reported the growing Gs of acceleration and the state of the capsule's pressure and oxygen supply. The Gs rose to four, then five, but his voice showed no sign of stress...
...proper attitude for firing its three braking retrorockets. They were not necessary for the flight; this time they were fired for practice. Then the retro package was jettisoned. Preparing for descent, Shepard reported that his periscope had retracted. As the capsule plunged downward into the atmosphere, and the Gs of deceleration climbed toward a punishing 10, the astronaut's voice grew gruff as he strained to make his breath behave. Then the capsule slowed; his words were distinct again...
...their cheers when they heard that Shepard was on his way, waited in silent expectation as he made his lonely flight. From time to time an announcer reported his progress; then Shepard's voice itself came over the loudspeaker. It was not clear. He was descending, and the Gs of re-entry were pressing him hard. Every man on the deck scanned the sky. When Freedom 7's big orange-and-white parachute popped open at 10,000 ft., the Lake Champlain came alive with cheers once more. "Damn!" the sailors shouted. "Marvelous...
