Bottom line - you have witnesses who saw ANYTHING your little heart desired depending on which ones you 'pick' ...
Using the figures in the table you provided:
928 witnesses saw something, with 258 of them seeing a streak.
239 witnesses heard something.
I'd say that was a sufficient number of witnesses to indicate far more than a cargo door problem. But then again, I trust the "general public" more than you.
"Rather, how many years of being an elitist does it take to take to ignore valid observations from "ANY general member of the public"? OUCH, , Thats gonna leave a mark!
