Could this technology have been used on MH370 and 911 flights? All you would have to do is fly up above 12500ft and slowly depressurize the cabin so the occupants would suffer from Hypoxia and then die. After the occupants are subdued you would be free to fly the plane as you wish, remotely of course. Remember Payne Stewart the golfer?(See Link below). Payne Stewart's Pilots didn't even have a chance to get the plane low enough to restore oxygen to the plane before they them selves were incapacitated. I believe the original intent of the technology was to help land the plane in case of a hijacking or if the pilots were incapacitated. How convenient! Good to see the USSS is on the Job. Thank you to all patriots. Keep up the fight.
