"In all my years of direct and indirect participation, I never witnessed nor even heard of an aircraft loss, where the wreckage was accessible, that prevented investigators from finding enough hard evidence to positively identify the make, model, and specific registration number of the aircraft -- and in most cases the precise cause of the accident. The government alleges that four wide-body airliners crashed on the morning of September 11 2001, resulting in the deaths of more than 3,000 human beings, yet not one piece of hard aircraft evidence has been produced in an attempt to positively identify any of the four aircraft. On the contrary, it seems only that all potential evidence was deliberately kept hidden from public view. - Col. George Nelson, MBA, U.S. Air Force (ret) – Licensed commercial pilot.

“Flight 175 is the aircraft that's alleged to have hit the South Tower. I don't believe it's possible for, like I said, for a terrorist, a so-called terrorist to train on a [Cessna] 172, then jump in a cockpit of a 757-767 class cockpit, and vertical navigate the aircraft, lateral navigate the aircraft, and fly the airplane at speeds exceeding it's design limit speed by well over 100 knots, make high-speed high-banked turns, exceeding -- pulling probably 5, 6, 7 G's. And the aircraft would literally fall out of the sky. I couldn't do it and I'm absolutely positive they couldn't do it." - Capt. Russ Wittenberg, U.S. Air Force – Retired commercial pilot. Flew for Pan Am and United Airlines for 35 years. Aircraft flown: Boeing 707, 720, 727, 737, 747, 757, 767, and 777. 30,000+ total hours flown. Had previously flown the actual two United Airlines aircraft that were hijacked on 9/11 (Flight 93, which impacted in Pennsylvania, and Flight 175, the second plane to hit the WTC). Former U.S. Air Force fighter pilot with over 100 combat missions.
“And also in all four planes, if you remember, none of the planes ever switched on their transponder to the hijack code. There's a very, very simple code that you put in if you suspect that your plane is being hijacked. It takes literally just a split-second for you to put your hand down on the center console and flip it over. And not one of the four planes ever transponded a hijack code, which is most, most unusual. ... Commercial airplanes are very, very complex pieces of machines. And they're designed for two pilots up there, not just two amateur pilots, but two qualified commercial pilots up there. And to think that you're going to get an amateur up into the cockpit and fly, much less navigate, it to a designated target, the probability is so low, that it's bordering on impossible." - Commander Ted Muga, BS CE, U.S. Navy (ret) – Retired Pan-Am commercial airline pilot. Aircraft flown: Boeing 707 and 727. Retired Civil Engineer. Retired Naval aviator. Aircraft flown: Grumman E-1 Tracer and E-2 Hawkeye.
It is important for people to understand that scrambling jet fighters to intercept aircraft showing the signs of experiencing "IN-FLIGHT EMERGENCIES" such as going off course without authorization, losing a transponder signal and/or losing radio contact is a common and routine task executed jointly between the FAA and NORAD controllers. The entire "national defense-first responder" intercept system has many highly-trained civilian and military personnel who are committed and well-trained to this task. FAA and NORAD continuously monitor our skies and fighter planes and pilots are on the ready 24/7 to handle these situations. Jet fighters typically intercept any suspect plane over the United States within 10 - 15 minutes of notification of a problem. This type of "immediate, high speed, high priority and emergency" scramble had been happening regularly approximately 75 - 150 times per year for ten years. ...- Robin Hordon – Former Certified Commercial Pilot.
