The crew of Gemini III snuck a corned beef sandwich on their spaceflight. Mission Commander Gus Grissom loved corned beef sandwiches, so Pilot John Young brought one along, having been encouraged by fellow astronaut Walter Schirra. However, Young was supposed to eat only approved food, and Grissom was not supposed to eat anything. Floating pieces of bread posed a potential problem, causing Grissom to put the sandwich away (although he did enjoy it)^[5] and the astronauts were mildly rebuked by NASA for the act. A congressional hearing was called, forcing the NASA deputy administrator George Muellerto promise no repeats. NASA took special care about what astronauts brought along on future missions.^[6][7][8]
