Two "Flight 175" taking off from Boston Logan: CONFIRMED
My personal 9/11 researcher "career" started with the detection of a duplicated "Flight 11" at Boston Logan Airport: one departing from Terminal B, Gate 32, at 7:45, the other one from Terminal B, Gate 26, somewhat later because the departure was delayed:
As opposed to that, the gate departure of United Airlines 175 is indisputable: 7:58 a.m., which is also confirmed by the database of the Bureau of Transportation Statistics (BTS):
However, the BTS database reveals a strange discrepancy regarding the "wheels-off time" of Flight 175 - i.e. the moment when the plane lifted off from the runway. The BTS notes a wheels-off time of 8:23, which differs distinctly from the "official" wheels-off time, which is 8:14.
This 8:14 take-off is confirmed by the ATC/pilot radio transcript and various radar data. So what about the 8:23? How was this datum being generated?
The wheels-off time of is triggered automatically by a mechanical switcher when the plane loses contact to the ground. The data are sent automatically to the airline via ACARS, and the airline forwards them to the BTS on a regular base. So apparently no human failure is possible. The fact that the gate departure 7:58 coincides with the official story suggests that the data are valid.
Being familiar with the duplication of Flight 11 at Logan Airport as well as the duplication of Delta 1989 at Cleveland Hopkins Airport, I arrived at the inevitable conclusion that this was another case of a duplicated plane - i.e. a "Flight 175" taking off at 8:14 and another "Flight 175" taking off at 8:23. However, there was no independent confirmation, so I hinted at the discrepancy on occasion, but always added a question mark -here, for instance:
I am now able to proudly present an eyewitness for the 8:23 wheels-offtime of Flight 175: Steven Miller, US Airways pilot, who was next in line behind Flight 175 to take off from the runway:
On the taxi-out in Boston, they ((the pilots of US Airways 6805)) waited at the runway's hold-short line, where Miller looked up to watch a United Boeing 767 take off, United Flight 175. The final weight and balance calculations from dispatch came over the ACARS at 8:05, and with that in hand, the crew was ready to fly. Wide-body aircraft produce especially powerful wingtip vortices - horizontal, tornado-like winds off the ends of the wings - which require time to dissipate before other aircraft can take off, so he waited the required three minutes after United 175 departed before he received his takeoff clearance.
(Lynn Spencer, "Touching History", p. 58)
A quick check with the BTS database reveals that USA 6805 had a wheels-off time of 8:28. Miller explicitly describes that he waited 3 minutes before getting takeoff clearance; adding a little bit for the timespan between takeoff clearance and actual wheels-off, Flight 175 must have lifted off the runway around 8:23-8:24. It is out of the question that Miller observed a plane that took off at 8:14.
Did Miller maybe see a different United plane? Very unlikely. Searching the BTS database for other United Boeing 767's delivers no results for the relevant time. There is a very slim possibility that a non-domestic United Boeing 767 took of just then, because the BTS database lists only domestic flights. However, Miller himself says it was Flight 175; so either he overheard the flight number when taxiing out, or, as someone who was frequently flying from Logan (as he says) he was familiar with the wide-body planes departing at that time.
The BTS database also reveals that the tail number of the plane that took off at 8:23 was N612UA. This was United Airlines Flight 175. And there is no proof that the plane that took off at 8:14 was indeed N612UA, leading to the conclusion that the pilot only pretended to fly United Airlines Flight 175.
