The sandwich had been purchased by another astronaut (and known prankster) Wally Schirra, who gave it to Young before the mission. Because crumbs could potentially become wedged in equipment or float into someone's eye, bread was forbidden on the spacecraft. Young's breach of the rules bought NASA a stern reprimanding from Congress. One representative said, "My thought is that ... to have one of the astronauts slip a sandwich aboard the vehicle, frankly, is just a little bit disgusting."
