Interesting Discrepency with Passenger Phone Calls and AA versus United Flights

In a previous post, I discussed differences between the AA and UA hijacked planes on 9/11.

A key point is that the two AA flights were not listed in the BTS database as taking off whereas the UA flights were.

I just realized something interesting related to this.

For the two AA flights (11 and 77), there was only ONE phone call from a passenger-- the famous Barbara Olson call from flight 77. This call is actually quite suspicious, and many people have wondered about its veracity.

More importantly though, for the two UA flights (175 and 93), multiple passengers made calls from each flight.

Why such a discrepency?

One interesting possibility is that flights 11 and 77 never really took off with passengers, and this is why they weren't listed in the BTS database and why there so few calls.

Anyway you look at it, the lack of passenger phone calls from the AA planes is very striking.

Note, flight 11 did have two prominent phone calls from flight attendants Ong and Sweeney. But they made little reference to the passengers, and no screams were heard in the background.

By the way, several months back, I analyzed one of the passenger phone calls from flight 175, from Peter Hanson. My thinking is this phone call is highly suspicious in its own right.
