Jan 22, 1967 – Gus Grissom held an unauthorized press conference in which he told reporters that the U.S. was “at least a decade away” from even contemplating a lunar mission. He was severely rebuked for giving that interview without permission.
Following this reprimand, Gus Grissom hung a lemon attached to a coat-hanger in front of a NASA emblem to indicate to any cameras that were present what he and his fellow crew members, Roger Chaffee and Edward White, thought of the Apollo program.
5 days later on Jan 27, 1967 – Gus Grissom, Ed White and Roger Chaffee were killed on the launch pad when a flash fire engulfed their command module during testing for the first Apollo/Saturn mission.
