i dont really know how to fully answer your question but from what ive gathered from watching documentarys about the crash. i think its that they discovered that there are many faults with how the 747 (not sure about toher aircraft) was design some that pop to my head that the low voltage wire that go through the fuel tanks where bundled next to each other in other parts of the aircraft, and that the airconditioning generators where places next to the fuel tanks which heated the tanks up as the aircraft was on the tarmac because of delay for a few hours with the aircon on. also they found out that jetfuel is flameable when it is heated to a vapour which happened on twa800 (but when a liquid its not), so this made new light on aircraft design to manufacturers.
i hope this helped
if u need more info on twa800 just ask

You mean "explosive" in vapour form (it "burns" quite well in liquid form) - given the right concentration of air-fuel (same principle as the "air-fuel bomb", BTW) - but aside from that - the issue was actually about chafing of wires against themselves and against the tube (inside a metal tube) and after the wearing away of the insulation, the resultant repeated arcing to that very tube followed by an erosion of the tube wall, then exposure of the arc to the air/fuel mixture. It's not quite as "simple" as you make it sound. It's one of those "HUH? We never thought of that!" issues (in theory, it doesn't happen, but proof positive again that Murphy is right). (Murphy's Law - "If anything can go wrong, it will, at the most inoportune time, with the worst possible consequences" - this mixes the law and a couple of corollaries as well)
As to WHY TWA800 is "important" - it represented an achievement of forensic aircraft accident investigation. Given enough parts, the cause of the crash can be determined and future similar incidents prevented
