In 1996, TWA Flight 800 exploded shortly after takeoff while bound for Europe. The cause of the explosion is generally believed to have been from a fuel tank.
Some days later, I was working on some particular project but thoughts of that disaster were running through my mind. An idea suddenly came to me about what might have caused such an explosion. I stopped what I'd been doing and immediately telephoned the FAA. I shortly found myself in a discussion with one Robert Swaim to whom I offered some thoughts and I followed up that discussion with an e-mail, part of which is reproduced here:

My suggestion was that the fuel tank wiring could carry RF energy from some passenger's cell phone into the fuel tank itself within which the tank's fuel gauge probe could act as an antenna feeding a waveguide, setting up standing waves inside the tank with high enough field strength to ionize a fuel-air mixture and thus set of an explosion.
Although Bob told me the tank had bypass capacitors on each wire passing through the tank's sheet metal shell, I suggested that those capacitors could have self resonant frequencies lower than that of the incoming RF in which case they would appear inductive and might not be effective bypasses at all.
Bob grasped my point and thanked me for opening up a new avenue of investigation of the matter,
Now we go fast forward and take a look at "National Transportation Safety Board, Investigation Into Trans World Airlines Flight 800" at the following URL: Investigation Report

What this report presents is utterly shocking.
I counted seventeen photographs of aircraft wiring defects that defy any personal expectations I might have once held. There are illustrated issues not just with 747 aircraft but with other aircraft (A300, 737, 767) as well.
Just two of those photographs are as follows:


Other photographs in this report show burned wire, connector damage caused by hydraulic fluid, chafed insulation, loose metal shavings and other wiring horrors.
Regarding Flight 800 itself, I do not subscribe to conspiracy theories. I do not believe for example that the plane was shot down. What I do believe however is that safety issues up to the time of that tragedy were very much in need of remedy.
The TWA crash was in 1996 while the latest date cited in the above report is 2001. Since then, the NTSB has concluded its investigation. Please see: NTSB Conclusion
However, I am led to ask the key question:
The TWA tragedy aside, what the h..... had been going on in the aviation industry in general and what has since been done about it?
