@hamster3null Purely from a physics perspective, a pressure wave traveling forward seems unlikely in a simple explosive decompression. I guess we have to define "explosive". I'm talking about a section of fuselage departing for whatever reason. This pops open like a soda can, not a bomb. Your examples all involve an actual explosion: TWA800 fuel tank/missile (whichever story you want to believe), Buk a missile, in either of those cases, the pressure wave is generated by an explosion, not the "explosive" decompression.
If of course there was a bomb on board, the same theory applies and a pressure wave could indeed have travelled front ways far enough to disturb the pressure ports.
