Flight 11 and the BTS Data-Base Discoveries Before 9/11

By Mark Conlon

The "unknown" statistic logged in relation to Flight 11 on 9/11 in the Bureau of Transportation Statistics (BTS) data-base is often used as proof that Flight 11 never took-off on 9/11, yet there are other instances showing the same statistic of "unknown" during the year of 2001 involving Flight 11.

(Flight 11 appears as a regular flight between BOS and LAX also on Tuesdays).

The BTS system returns "UNKNOWN" along with the usual 00:00 data for September 4 and July 10, 2001. Also, there's no data at all available for August 7, 2001. In all other instances AA-11 (Flight 11) appears to have flown on all Tuesdays before 9/11.

American Airlines "Flight 198" was the flight number with the plane tail number N334AA, which is a pendulum flight with Flight 11. Flight 198 arrived at Gate 32 in Boston, Logan Airport early in the morning on September 11, 2001. Although the reported date is 9/10/2001, the plane took-off from SFO on the west coast at 21:49 on 9/10 and actually landed at BOS on the east coast at 6:03 the next day on 9/11.

Apparently this detail created lot of confusion among 9/11 researchers, however this is the last tracked Flight for the plane - tail number N334AA before becoming the infamous AA11 on September 11, 2001.
