the tap: 911 aircraft airborne long after they 'crashed'

the tap: 911 aircraft airborne long after they 'crashed'

Apart from the rather obvious points that both flights were cancelled that day,an engine turned up on a New York street which could not have come from either plane even if they had flown!!  Pratt & Witney and Rolls Royce built the engines for this type of plane.
The one which turned up was not on either plane which was due to fly prior to cancellation!!  That alone was enough for me. Why plant the wrong engine, with serial numbers on it, if it were terrorists???
