. . Impractical Reality

develop a software to empower the air traffic controllers (ATC) to instruct the flight management computer FMC (who give instructions to the autopilot) to be remotely trigged to arm the “Autoland mode” and perform the speed altitude restrictions Flaps setting and gear extension accordingly
This accident is about cabin pressurization failure and about the flight crew's failure to follow trained procedures, either or both: 1- to check their oxygen masks and oxygen supply prior to flight, and 2- to don their oxygen masks in a timely manner after pressurization failure.

In this scenario, with the pilots already dead or unconcious, stefanoperer proposes that ATC be given the capability to "take control" of the airplane and get its autopilot not only to autoland on a specific runway, but also to reconfigure all autopilots in all jets to also lower the gear and flaps and to arm autobrakes and to operate reverse thrust to effect a safe full stop landing. Needless to say, at FL340 the pax oxygen supply will be good for maybe 20 minutes before pax will expire; this would necessiate also an autopilot mode of initiating an automatic emergency descent, perhaps long before ATC is appraised of the depressurization failure. The already overworked autopilot would then also have to send a signal to ATC notifying it of such failure.

Entirely conceivable, but impractical. What's next: build jets with huge deployable parachutes in case of catastrophic flight control malfunctions...?
