There has barely been any reporting on the incidents. One was with United and the other with Qatar Airways, both extremely similar where the planes started rapidly descending immediately after take off, coming within less than a 1000 ft of the ocean and then suddenly shooting up again.
To me it reads like some systemic failure which caused the falls and some automatic crash detection system that kicks in when the plane nears the ocean surface and automatically climbs up.
Fucking scary shit.
What if they made planes that go on the ground? You could take the wings off so they would take up a lot less space and you'd only need one engine so I bet it would be more environmentally friendly as well. Maybe you could have some kind of dedicated track system for them so they could go really fast, that would be neat.
