The Intentional Backfire
Alright, an aviation puzzler—don’t worry, it still kinda smells like motor oil:
Back in the early days of aviation, mechanics noticed that airplane engines would regularly backfire through the carburetor—loud bangs, flames, the whole works. Bad for the engine, worse for your nerves.
They checked everything… and eventually discovered: Nothing was wrong with the plane.
In fact, the pilot was doing it on purpose.
Which raises the obvious question:
Why would a pilot intentionally make the engine backfire, scaring himself silly and risking damage when it seemed completely useless?
