Had to dump cargo once in a DC-3 between Agadez( Niger) and Tamenghest (Algeria) because we had lost a motor and we were way overweight. We had a motorcycle raceing team from Begium onboard originally but left them behind to get home on a different aircraft. We also had the old engine that I had changed in Agadez, on board as well as the raceing teams equipment. I had to throw out ( while in flight ) everything from generators, tools, drums of oil, motorcycles and parts. After I had everthing out the door we were barley able to maintain altitude so I was going to start taking the engine apart and throw it out too but...I had already threw out the ships toolbox.
The folks on the ground were probably very excited to see all this free stuff raining down on them.
