My older brother was a Crew Chief on a Chinook helicopter in Veit Nam. They would make cargo runs carrying fish oil, rice, pigs, and chickens to the villages. On one such cargo run the pilot asked my brother if he thought those chickens could fly at the altitude they were cruising. My brother said, "Just a minute, I'll see." The pilot came back on the intercom radio asking how the chicken did. My brother reported that chicken did not do to well, and that he thought maybe the cage was too heavy for it.
