This is super neat.
It was originally uploaded in 2010, but became newly viral again this week and the source is so much better than the crapped-out clip that went meme.
Enjoy, unmute, turn up the volume.
From the original video description by AgentJayZ on YouTube:
Rare opportunity to demonstrate a sound that no turbine tech wants to hear… ever!
… because it means you have to get that thing you dropped in there back out. Jet engines are heavy and sensitive, so it’s a big deal to lift one up and turn it over, just to hopefully drop out a small piece that some dumbass dropped in there.
If that does not work, the engine must be disassembled to the point where the item can be retrieved. This will be an expensive process.
… that’s why it’s a bad sound.
