Not sure if anyone ended up doing anything with this idea, but I started one up at:
http://impdb.org (The Internet Movie Plane Database).

It's very easy to register and add content. I think "aircraft" would have been better to use in the name, but for a reason I can't remember now, I didn't use it and I didn't see this site/forum/thread until after.

It's still in it's early stages since I just started it and especially since I don't have a lot of time, but I am continually adding content to it.

Anyway, check it out if you guys get a second. Drop me an email if you have any comments, or suggestions at support@impdb.org Thanks!

BTW, love IMCDb.org!
