So, lets go on what we have. The last known altitude reported for AA77 was 7000 feet. And travelled 33 miles in 5 minutes. Thats 6.6 miles per minute or 396 knots (Update: FDR data shows 325 knots average airspeed. 9/11 Commission Report is inaccurate). Then the aircraft began a 330 degree spiraling dive, leveling at 2200 feet to accelerate to the Pentagon while continuing descent. He started the maneuver at 7000 feet, 396 knots, dove almost 5000 feet within a 330 degree turn and covered 5 miles in about 3 minutes. According to the 9/11 Commission Report, the final impact speed was 530 mph. Update: FDR is now available and the 9/11 report is inaccurate in terms of impact speed.S, ja, enligt Pilots for 9/11 Truth s flg Hanjour i s fall en Boeing 757 som om han aldrig gjort ngot annat.
So lets take an avg speed throughout the dive of 430 knots (7 miles/min). We know a standard rate turn is 2 mins for 360 degrees. So lets say he completed the turn in just under 2 minutes. Since we dont know bank angles or speed. That means he was descending at better than 2500 fpm dropping almost 5000 feet only gaining 30 knots. No problem for guys like you and me, but for Hani? We'll get to him later...
Once this maneuver was completed, without going into a graveyard spiral, he started to pull out of the descent at 2200 feet and accelerated only 30 knots more at full power to 460 knots in a descent from 2200 feet to the pentagon in about a minute (Whats Vmo at sea level for a 757? Flap speed? Since it looks like he may have found the flap handle only accelerating 60 knots from 7000 feet, the from 2200 feet at full power). AA77 crossed the highways, knocking down light poles, entered ground effect, didnt touch the lawn and got a 44 foot high target (Tail height of 757) into a 77 foot target completely, without overshooting or bouncing off the lawn, or spreading any wreckage at 460 knots. With a 33 foot margin for error. Wow, impressive. Takes a real steady hand to pull that off. I know it would take me a few tries to get it so precise, especially entering ground effect at those speeds. Any slight movement will put you off 50 feet very quickly. Im sure we all would agree.
