Hi Stretch, are you sure about that? I don't know for sure. I've worked in air cargo for 24 years. Every conversion I've ever seen with a passanger aircraft involves the airplane being completely torn down, cleaned of contamination, etc. During the process they usually give it a new coat of paint. FedEx and UPS both have a reputation for being very matticulous about this. I haven't seen any MD-11's at UPS and I thought the ones that FedEx were delivered as freighters painted. Going back a few years I think FedEx converted a bunch of DC-10's to freighters. Finding photos of something like that, especially all the way around could be pretty tough. It sure would be an interesting subject though. I'll ask some of my friends and see if they have any ideas.
