Now we move into the realm of science fiction, or even fantasy. Suppose that there is a teleportation device, carried back to us by time travelers, to inject these mysterious occurrences into our everyday lives, at a time in history where there was great turmoil about bacteriological agents, and terrorist attacks using airliners. A small piece of a structural part on the tail surface of the airliner was teleported away, so it looked like a stress failure, and a small quantity of anthrax spores were teleported into the woman's nasal passages.
But of course there shall be developed much more rational explanations, for each of these seemingly unrelated events. Just keep in mind, that not all the frontiers have yet been explored, or even defined very well so far.
1.Thrust reversers are normally stowed in a mechanically locked position, so that in case of a hydraulic system failure they remain closed.
2.Hydraulic pumps are mechanically driven by the engine during and after engine start. A "cut" hydraulic line would spew tremendous amounts of fluid while under pressure at 3000 psi and trigger a cockpit warning light. Hydraulics power all major aircraft systems including brakes and nose-wheel steering. I doubt Flight 587 would even have been able to taxi to the runway for takeoff had this "cut line" scenario occurred.
