A closer look

Smuggling a highly unauthorized corned beef sandwich onto the Gemini 3 spacecraft in 1965 remains one of the most hilariously dangerous things ever done in the history of space transport. Astronaut John Young hid the deli sandwich in his spacesuit pocket just before launch, pulling it out to share with fellow pilot Gus Grissom once they were in orbit. In a zero-gravity environment, the bread immediately began breaking apart into floating crumbs, which threatened to get inside the spacecraft's electrical panels and short-circuit the entire multi-million dollar mission. Congress actually launched a formal investigation into the sandwich incident, forcing NASA to implement strict anti-deli rules to ensure future astronauts could not blow up a spaceship with rye bread
