I have made my 2nd attempt petitioning the Obama Administration to investigate the inconsistent 9/11 takeoff times. The petition, which needs 150 signatures to become visible to the public, is here: http://wh.gov/89w
Investigate the 9/11 Inconsistent Takeoff Times
On 9/11, did UA175 take off at 8:14 or 8:23? Did UA93 take off at 8:42 or 8:28?
UA175 took off at 8:23, according to the Bureau of Transportation Statistics. The BTS reports detailed departure statistics on all commercial flights in the USA. The reported Wheels-Off times are automatically transmitted by each aircraft when the wheels leave the runway.
UA175 took off at 8:14, according to the 9/11 Commission's Report. This time was based on FAA communication transcripts and various National Transportation and Safety Board studies.
UA93 took off at 8:28 according to BTS, at 8:42 according to the Commission.
No official investigation has publicly acknowledged the discrepancy, let alone explained or resolved the discrepancy.
