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.
