Airbus pilots!

Is it possible that the 911 hijackers choose Boeing planes since it might be difficult to get an Airbus to dive so close to the ground?

On the contrary, I think it would have been easier for the hijackers to fly Airbuses. There just are'nt many Airbus training facilities in the US, and the cost is more than Boeing products.

Perhaps they desired reliable transportation to their objectives.

(1) Microsoft Flight Simulator at the time only offered Boeing airplanes in their product, it is not until MFS X that they decided to include the Airbus 320.

(2) The Boeing planes (767,757) were bigger than most airbus planes owned by American Airlines (UAL, AA) which are much smaller (319,320), the only airlines who at the time had a bigger airbus, was NW,and US air, (330), but why bother, when their was a handful of 767 and 757s comming from the east to the west with a full tank of gas.

You guys think too much...The plan for 9/11 evolved - its started as a job involving crop dusters. Atta was denied a loan to buy some cropdusters so he made the decision on his own to shift to hijack commercial planes and use them instead. OBL didn't care or even knew what was happening - he had other manage / take to fruition operational plans. Once the decision was made - the muscle was recruited / trained / and send to the US to assist in the operation.

BTW - OBL and company doesn't abandon an idea until it is made to work. In 1996 they tried to blow - up a plane using liquid explosives. They will not stop until they do it. We should be more concerned about preventing that than wasting time on why they didn't use an Airbus.

You can crash a 'Bus. There is NO system that prevents banging into the planet.

And you can now discount your sources as being unreliable and uniformed about 'Busses.

Nope. No such system.

You may be confusing the envelope protection with the ability to hit the planet. You can not exceed the pitch limits so no, you can not dive a FBW Airbus at 60 degrees... limits are 30deg nose up, 15deg nose down, 67deg bank angle.. in NORMAL Law. You would have to fail some systems to go outside the normal envelope to get to Alternate or Direct Law control and to do that requires knowledge that is beyond many of the guys who routinely fly the 'Bus.

And the main thing was they had trained on Boeings and wanted a big airplane (mass) with lots of fuel (heat potential) to create the bomb to destroy the Towers.

To add and clarify what III Corps mentioned:

On all Airbus planes other than the older A300 and A310, computers prevent the pilot from putting the plane into a climb of more than 30 degrees where it might lose lift and stall. The maximum bank or roll allowed is 67 degrees. The plane's nose-down pitch is limited to 15 degrees. There are protections against overspeed.

And the computer won't allow the plane to make any extreme maneuvers that would exceed 2.5 times the force of gravity.

So I guess, I was wrong, you can crash an Airbus, as long as you don't go beyond its limits. However no one can disagree, that it (crashing/911) was much simpler in a Boeing, and the terrorist knew this.

I don't like that a computer keeps a pilot from doing anything.

you're barking up the wrong tree:

Boeing's scary new autopilot patent
...once activated, removes all control from pilots to automatically return a commercial airliner to a predetermined landing location.

...the system has its own power supply, independent of the aircraft’s circuit breakers. The aircraft remains in automatic mode until after landing, when mechanics or government security operatives are called in to disengage the system...
