Pan-Am Flight

The investigation into the sabotage of Pan Am Flight 103, which left 269 dead, indicated that the explosive used was Semtex H, a plasticized mixture of hexahydro-l,3,5-trinitro-s-triazine and pentaerythritol tetranitrate, and that the amount used was half the quantity that the fledgling technique of Thermal Neutron Analysis (TNA) was designed to detect. Although the placement of the explosive device was fortuitous (from the terrorists point of view) and the suitcase had not been screened by TNA, this event killed the TNA prototype program. 

Then the leader of that project, Irving Sigal, was killed on the Pan Am flight that exploded over Lockerbie, Scotland. Another clutch of scientists bolted to form their own biotech, which they named Vertex Pharmaceuticals. 

Pan Am Flight 6 Accident. This accident occurred on October 16,1956, and is associated with the Pan American World Airways (Pan Am) Flight 6 (aircraft type Boeing 377 Stratocruiser), a schooled flight from Honolulu, Hawaii, to San Francisco, California [12]. The flight was forced to ditch in the Pacific Ocean because of the failure of two of its four engines. Fortunately, all people on board survived.
