If an airliner turns out to be carrying a bomb, hidden in the luggage/freight hold, today’s invention is an internal arrangement designed to protect the plane and its occupants.
The baggage etc would be held in containers as usual, but these would be located on heavily reinforced racks so that if a bomb detonated, the containers would be expelled rearwards from the fuselage, by the explosion itself, leaving the plane free to continue.
Each container would have its own parachute to allow later collection of the luggage etc and also any forensic evidence.
This system could also be used in the event of eg an engine failure. Discarding all that extra weight (as well as fuel) could allow easier manoeuvring and safer landing.
