Please tell me the difference between a 757 and a 757AA

I know I will find an expert here, I will tell you straight out I know very little about aircraft, so in your description tell me all, don't assume I know anything about it. TIA

As far as I know there is no version of the 757 called the 757AA, it might just refer to a 757 belonging to American Airlines? Whats the original reference that led you to ask the question? That may help one of us figure it out.

I would venture to support wayno's answer, that it is an American Airlines 757. Either that or its a different TYPE of 757. You know like the 737-800. But I think thats an airline deisgination. Not a civilian aircraft expert here either . Stranget hought considering I wanna build them some day.

The american airlines thingie sounds right.
based on the image below called 757aa.jpg


I would assume that is correct

Not the humerous version that it has air-to-air missiles equiped.

Thats probably correct it was just a way of identifying a plane as belonging to that particular airline and I with my total lack of knowledge on planes assumed it was a different type or smaller version of a757 plane. Thank you all for your time and answers. goose
