Most likely a waste of a thread, but.... I'm bored and curious and not very good at airplane identification. AA's twitter stream just sent out a link to a photo of an AA plane in a hangar saying, "Guess what? Our fleet's growing, and here's a sneak peak! Check in next Monday for more." Here's the link. Can anyone tell what type of plane they're working on? Either way, it's always fun to see some behind the scenes activity.
