A small bomb in luggage compartment caused a tiny hole in the fuselage. THEN a piece of Luggage jammed in the hole and caused "Fluid Hammer" a MASSIVE pressure build up that then caused the entire fuselage to tear open and disintegrate.

Same thing happened: https://en.wikipedia.org/wiki/Aloha_Airlines_Flight_243 "Pressure vessel engineer Matt Austin has proposed an additional hypothesis to explain the scale of the damage to Flight 243. This explanation postulates that initially the fuselage failed as intended and opened a ten-inch square vent. As the cabin air escaped at over 700 mph, flight attendant C.B. Lansing became wedged in the vent instead of being immediately thrown clear of the aircraft. The blockage would have immediately created a pressure spike in the escaping air, producing a fluid hammer (or "water hammer") effect, which tore the jet apart. The NTSB recognizes this hypothesis, but the board does not share the conclusion. Former NTSB investigator Brian Richardson, who led the NTSB study of Flight 243, believes the fluid hammer explanation deserves further study."

They need to design aircraft to prevent "Fluid Hammer."
