This is a test demonstrating what happens when a foreign object enters a jet engine before buying it dinner first.
Wide Body, Blade-Out Jet Engine Test. Short video showing what happens when a foreign object such as a large bird is ingested in a jet engine. You don't want to be onboard!!!! The joke during training was that you could ingest a 5 lb. bird at 250 kts.......... or a 250 lb bird at 5 kts. They actually have a "chicken gun" they use to fire the chickens into the engines for these tests.
Oh man, just imagine if -- wait, did that just say chicken gun? I want a chicken gun.
UPDATE: So apparently this isn't the chicken gun test after all. Youtube user dknric is a liar! Just like your parents -- you were adopted.
Thanks to Ain, who once sucked a mourning dove into his jetpack's engine and had to crash land in a tree, where he befriended a squirrel. Yay for happy endings!
