Is this your main question concerning the maneuvering of the alleged flight 175? If so, let me know if that's the best way to ask it. For example:
"Can a 767-200 perform a high speed sharp banked angle turn, while not drastically slowing down, particularly close to sea level, at say, 700 ft?"
Why not ask the exact questions that will give the answers to help either validate or dismiss the parameters the NIST used in establishing their
"more severe damage model"? Why are we talking about 60 degree bank angles when there is no evidence of either plane rolling to a 60 degree angle
during the approach to, or at the impact of, the buildings?
Here are the parameters the NIST used to model damage due to impact:
EDIT NOTE: I have rewritten these questions to use the data listed in the following tables from NISTNCSTAR1-2B - "More Severe" damage model
along with the roll angles listed in Tables 7-4 and 7-5.
So if we're going to ask questions that produce answers - let's ask ones that produce USABLE answers.
From a performance standpoint:
1. Is it possible for a 767-200 to achieve 472 mph in a 7.6 degree pitch down and a 25 degree roll at approximately 960 feet altitude? (taking 10
2. Is it possible for a 767 to achieve 570 mph in a 5.0 degree pitch down, 13 degree yaw, and a 38 degree roll at approximately 810 feet altitude?
From an airframe standpoint:
3. Is it possible for a 767 airframe to hold up to the conditions of 1?
4. Is it possible for a 767 airframe to hold up to the conditions of 2?
From a maneuverability and controllability standpoint:
6. What control forces would be required in 1?
6. What control forces would be required in 2?
From a piloting standpoint:
7. Do you have to have a pilot license or any training past what cockpit controls do what in order to hit a 209 feet wide skyscraper under the
conditions of 1?
8. Do you have to have a pilot license or any training past what cockpit controls do what in order to hit a 209 feet wide skyscraper under the
conditions of 2?
Those are the answers we need to get in order to validate the assumptions used by NIST in their impact damage models - and to answer for ourselves
whether the flight parameters they used were achievable either by plane or pilot.
