We found a couple of drop tanks...external wing fuel tanks...from an Air Force jet. They were kinda sleek looking things and at first we thought we had bombs.
They were pretty big. Once we figured out what they were I called Beale AFB, talked my way slowly...very slowly... up the chain of command through several different people who kept referring me to somebody else. Took most of the morning. They weren't particularly interested in getting them back. If we wanted to haul them clear down to Beale they would accept them but they weren't coming up to get them.
The loader operator made a barbecue out of one and I used the other one for a watering trough for my cows
