“All it would take is a shoe bomb and the plane would immediately de-pressurize and that would be it while flying at 35000 ft.”
Depressurizing the plane by itself wouldn’t be catastrophic. Oxygen masks would deploy for passengers and crew alike. Air pressure would equalize fairly quickly and then it would just be cold. Unless the cockpit crew were disabled or the flight systems knocked out, the pilots could at least get a mayday out or squawk a distress code.
I sure wouldn’t want to be on that flight, at 35,000ft
and 500 mph. Maybe a window blow out might be survivable
but I wouldn’t want to be on the ride down to breathable
air. Zooooow!
