Lol wtf!? I get that it was past the point of no return and had to commit to take off but a 90 min wait to land again seems insane.
747s are designed to lose an engine in the middle of the Atlantic Ocean and still be able to return to land safely. Literally.
https://en.m.wikipedia.org/wiki/ETOPS
90m isn't ideal, but perfectly fine.
It's weird they designed it to lose an engine. They should have designed it not to lose an engine. That would have been better.
(((THEY))) don't want that, though!!!!
Engines Turn Or Passengers Swim
ETOPS is not required for 747s. Being a 4 engine plane it can run fine with him three. So an engine failure is not an actual emergency although you will still need to land cause of the reduced performance running with three engines.
Can we have other internet infrastructure built that way too?
Well, we have already.
The Internet was designed to be resilient against nuclear war. Most protocols are resilient, it's just been the last few years that some companies abused their positions (Cloudflare, Google) and it also came to light, that some protocols have been designed with a tad too much trust (BGP, SMTP).
I am aware.. I meant more so with the recent trends.. We have p2p ffs. So its not the tech its how its being built.
My guess is that they wanted the plane to use up most of the fuel before attempting the landing. As long as the plane is flying, the speed of the plane adds a level of safety to the fire. Once the plane lands and slows down, that fire would start affecting the rest of the wing much more, but there can't be a big kaboom anymore if the fuel tanks are empty.
Long distance 747 flighs usually take off above the maximum landng weight. They need to get rid of the fuel before landing, but the 400 has the ability to dump fuel.
The engine wasn't on fire. The engine had a surge on takeoff. They would have shut the engine off as it might have been damaged, but the plane was not on fire. They would have landed much sooner if it was.
Many articles describe engine surges with language that, while not technically a lie, is written to make readers conclude that the airplane is actually on fire.
This guy airplanes. Thanks for the info kind person!
Landing overweight can be even more dangerous. The engine was shut down and they can fly just fine on 3 engines.
Plane was not on fire. Passengers were in no immediate danger. Its safer to keep flying and prepare than make a hasty landing for no reason.
Apparently the engine wasn't on fire either, falsely reported according to others here
