After half an hour of postlanding cockpit checks with the hatches closed, Astronauts Virgil I. Grissom and John W. Young practiced the emergency egress procedures developed by the flight crew training staff for Gemini. Both pilots then egressed through the left (command pilot's) hatch, after first heaving their survival kits into the water. Each astronaut then practiced boarding a Gemini one-man life raft. Swimmers were standing by in a larger raft.
