Sad news for families. Same question as usual, with Malaysian airlines.Total mystery.

Every drone has video camera recorders, and multi million dollars state of the art planes has nothing.

If that SD card video recording , one from pilot cockpit and another from passenger cabin could shed some light on causes ?

Without the need for months of investigations to has the slightest clue ?

This is just my vote to have video recorders compulsory in all passengers airplanes one day.
