Many of the advances in space travel have come from the hard-won experience of past failures, but NASA and its brethren also rely on paid volunteers, who subject themselves to all manner of surreal and bizarre experiments that attempt to replicate living in space. For instance, in 1962 NASA funded a motion sickness study in which twenty Navy cadets were harnessed to a chair mounted on its side, and then rotated, rotisserie style, at up to thirty revolutions per minute, approximately six times faster than the chickens turn at Boston Market. (Only eight of the twenty cadets completed the exercise.)
