As a Crew Chief on A-10s, nose art was not allowed, except for the shiney Tigers Teeth we had for the history of the 23rd. But Nose Ladder Door Art was a whole different story. The art work on the inside of the ladder doors is great, and with the war, much was brought back. Some of the A-10 web sites have good collections of them. I will look for a link and try to post it.
A-10s may not look pretty, but the sure work pretty, unless your at the receiving end.....
