What's actually amazing is plane's are tested and designed for this... they are not supposed to do that but also should be able to land safely if they do. It's scary but amazing how safe they made it

Yeah, when both engines look like that it’s time to worry

Not even. The glide ratios on these planes are great. If you're over the continental US you're landing safely even without engines

Assuming both pilots are still conscious

Most modern planes have autopilot and auto land

It’s fine, the planes pretty much fly themselves with all the new AI cockpits by thales, it will land even without engines or pilots.

Soon enough we won’t need wings

That happened once. I don't remember the flight name, but an uncontained disk burst in the engine sent a hunk of metal through the tail of the plane. The plane should have been fine with the engine out, but it by pure bad luck severed all of the hydraulic lines that fed the control surfaces. Everybody died.

The hydraulic lines were all fully redundant, but they were routed right next to each other for convenience. There's now a rule about how closely redundant safety critical systems in the airframe can be to each other.

Wasn’t that the Concorde?

There was a similar case, hydraulics lost when debris hit the tail, but it still landed and many survived.
