Eddie sold both DC-10s. The first one (FedEx) was since destroyed. Not sure what happened to #2 (UPS).

In my experience, the difficult thing about analyzing these things is the estimation of the loads. I am a Stress analyst for Lockheed Martin on the Space Shuttle's External Tank, so the actual stress analysis is easy for me (gotta make some slightly conservative assumptions for wood strength). But what do you use for the loads? Typically what we have always done so far is guess at a max G level and go from there. But I think this is usually VERY conservative, thereby leading to way over-built structures.

Anyone know what they did for either B-52? Seems the British AMA would require some analysis demonstrating adequate margins.
