The odd ones are easy to sort out:
The explanations are vague, often unbelievable.
And clincher is that no action is taken to ground that type of aircraft or install fixes. For example, center fuel tanks on 747s were NOT pumped full of nitrogen, nor are they now filled for all flights. Either a center fuel tank explosion is still possible, or it was never a problem in the fist place.
Airliners are STILL sitting ducks. The TSA was a useless waste of billions of dollars. And the travel experience could not suck more. (And yet, every time I say that, the airlines prove me wrong.)
