Lemon, metal coat hanger
In January 1967, Virgil 'Gus' Grissom, an American astronaut,held an unauthorized press conference in which he informed reporters that the United States 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 later came out of a water tank reduced gravity simulation of the supposed lunar landing module, and hung a lemon attached to a coat-hanger in front of a NASA emblem to indicate to any cameras present, without speaking, what he and his fellow crew members, Roger Chaffee and Edward White, thought of the Apollo program and as a means to critique the space program to date. This act of defiance is both simplistic and poetic in its essence, an act of transgression. The single mute action of a man, becomes a portrait of both the person and a remnant from a silent protest.
