Reply to comment by Regular-Cranberry-91 in TIL that passenger jet engines produce most of their thrust from fan at the front, not from the jet exhaust, and that this is called a high-bypass engine. by Rilot

Pratt & Whitney has a facility in Canada where frozen turkeys are launched into running jet engines.

Formerly frozen turkeys. They thaw them out before they fire the into the engines, as a large block of ice is rather more damaging to an engine than a bird. The bird ingestion test is part of the type approval for all aero-engines, not just P&W.
