Just wanted to tip you guys about a site with some very good blank airliner templates. Check out http://www.norebbo.com/tag/airliner-templates/
These are all made by Scott, the guy behind the norebbo.com site. All rights belong to him, but we're free to use them as we please. But a link to his site or mention of Norebbo would be appreciated:
"Hi! My name is Scott, I am a 3d and 2d illustrator, and I have been making stock illustrations since 2006. All of the graphics on this blog have been created by me and are free for the taking - if you see something you like, please feel free to use it for your own blog or articles (with a link back to my site, if possible). Enjoy!"
Example of the quality of his work:
