The Misfortune of Al Shepard: 50 Years Since Gemini 3 (Part 1)

In addition to carrying the equipment of the prime crew, Gemini 3 backups Wally Schirra (third from the right) and Tom Stafford (second from right) saw to it that they fulfilled the mission’s humor requirements. As a result, Gemini 3 would forever come to be known as “The Corned Beef Sandwich Mission.” Photo Credit: […]
