SURREAL FOOTAGE showing American airmen conducting a bizarre experiment into the effects of weightlessness on cats and pigeons has remerged this week. The video shows a group of three U.S. Air Force personnel taking two cats and three pigeons up on a flight in a C-131 Samaritan plane, nicknamed the ???Vomit Comet??? due to its use in antigravity testing for pilots. The men first demonstrate how a cat will react if dropped upside down from a height, with the video showing the two felines adjusting their bodies so as to land on their feet / mediadrumworld.com
