Gus GrissomThe second American in space is Virgil “Gus” Grissom, pilot of the Mercury 4 capsule Liberty Bell 7. Like Alan Shepard’s flight, Grissom’s launch reaches an altitute of 118 miles and splashes down 15 minutes later, but mechanical problems with the explosive bolts to release the capsule’s hatch allow water into the vehicle. Grissom has to bail out at sea, wearing a spacesuit that’s rapidly taking on water, while Liberty Bell 7 sinks to the bottom of the Atlantic. Grissom weathers repeated accusations that he manually blew the hatch and caused his vehicle to sink, a claim which is later disproven.
