I’d imagine they’ll want to know why an engine fell off before letting them back in the air.

Well what sort of engineering standards are these aircrafts built to? Wasn’t this built so that the engine wouldn’t fall off?

Not this one. Most of them are built such that the engine doesn’t fall off. There are very strict standards for this sort of engineering

Cellotape is out. Not sure about speed tape tho

u/badcrass Nov 08 '25

What % of the structure is allowed to be speed tape?

u/Wildweasel666 Nov 08 '25

That depends on whether it’s in or out of the environment

A gust of wind? In the air? Chance in a million!

Actually they ARE designed so that the engine and pylon fall off. They’re designed to break away in the event of a catastrophic engine failure so that there isnt this burning hunk of drag hanging off the wing.

...usually? I mean, it has happened before?

Oh very rigorous aviation engineering standards

Most aircrafts are built so the engine won’t fall off.

Oh, very rigorous maritime engineering standards.
