Something that you neglect to remember is that the plane that struck the Pentagon was initially headed directly towards the Whitehouse, then executed a high-speed, high-bank turn around DC, lined up on the Pentagon and managed to nose into it at mid-level. It is VERY difficult to control an aircraft in a high-speed nose-down attitude. ESPECIALLY those that are less than "sporty" in flight characteristics. > halfway-smooth flight path from someone who has played a MS-Windows > flight sim for a few months, but - if he was going from switching off > autopilot to keeping the plane pointed at something the size of the > WTC.......

Think about it. The WTC is not actually that large of a target. Granted, it's was easy to pick out from the air but, lining up on it and maintaining a flight attitude that will keep you in the air until impact is a different story. If you've seen footage of the second plane impacting, look at the last second attitude correction. Had the individual who was flying the aircraft not made that correction, it would not have struck the building. (At least THAT building.) Also, airspeed is very important if you want to keep an aircraft aloft. ESPECIALLY when you are pulling turns. If you're just above stall and try to turn the aircraft, you don't turn -- you fall. > ... or train for the two/three more common types, then pick a flight *on > the day* that actually is flying that type of plane. book seats at the > last minute (not a problem for domestic flights) or pre-book three or > four different seats per attacker, and each picks a flight with the > right sort of plane from the "pool" of available flights. There are mechanisms in place that would detect this type of behavior. (Prebooking multiple flights for the same individual.) --- John Fraizer EnterZone, Inc
