I read recently about how fighter planes are frequently scrambled in response to the use of certain words in transmissions from planes. Words like “bomb” and “hijack”.
The fighters are supposed to deflect an aerial attack by first making rude gestures at some incoming plane, followed after a decent interval, by shooting it down (presumably so that it crashes somewhere less publicity-worthy -ie anywhere that isn’t London).
Today’s invention attempts to avert this disaster. In the event that an airliner was suspected of being used in an attack, a special aircraft would be launched from the nearest airport.
This would be effectively a flying bombproof runway or deck. The deck plane would approach from underneath and behind (invisible from inside the captive aircraft).
It would activate the engine cutoff valves, causing the plane to settle onto the deck and be held in place by clamps on the wings. The captive plane could be boarded by special forces and the combined craft landed somewhere discreet very rapidly.
