The Govt's own database(which is an extremely accurate and well managed one)said those flights never flew that day. Untill later "changed" to say they did.
WikiScanner discovered that American Airlines changed their Wikipedia entry to state that Flights 11 and 77 never flew on 9/11.
Original entry was:
Two American Airlines aircraft were hijacked and crashed during the September 11, 2001 Terrorist Attack: American Airlines Flight 77 (a Boeing 757) and American Airlines Flight 11 (a Boeing 767).
New entry is:
Two American Airlines aircraft were hijacked and crashed during the September 11, 2001 Terrorist Attack: Flight 77 (a Boeing 757) and Flight 11 (a Boeing 767). Although these flights were daily departures before and a month after September 11, 2001. Neither flight 11 nor 77 were scheduled on September 11, 2001. The records kept by the Bureau of Transportation Statistics (
www.bts.gov/gis/) do not list either flight that day.
