Just because someone is a retired Colonel is no guarantee they don't have a number of screws loose in the attic, and this fellow is a perfect example.

First off, I doubt he has much experience in aircraft accident investigation. I do, working at AFIP on major crashes like Tenerife & Mt Weather. His claims about identification of specific planes are just plain bull, and he doesn't even seem to be aware that the black boxes WERE found in all four WTC-related sites. I suspect he may have diddled around on a few minor accidents, obviously not as a principal investigator, and he's blowing smoke to fuel his politically-based delusions.

As plenty of aerospace sites will confirm, the engine parts & landing gear clearly visible in media & official photos ARE exactly right for that aircraft, and unless one wishes to conclude that thousands of military people, civilians, fire, police, medical and recovery people on-site are ALL in on the plot, and helped plant all those plane parts, bodies and body parts (photos of which are easily available online, for the morbidly curious), it's pretty obvious that Nelson is full of it.

I could pick his letter to pieces, as could most real pilots or aircraft investigators, but it's hardly worth the trouble. The committed zealots who NEED to believe this nonsense will never be convinced. Rational people will probably smell the fecal odor emanating from Col Nelson's literary "droppings."
