As groundhandler at MST, I have loaded horses onto B707's and DC-8's, squeezed computers into AN12's, stuffed millions and millions dollars worth of fags down IL76's and sent tons of meat to the Kingdom of Jordan. Unloading an AN124 stuffed up to the ceiling(cranerail) with Adidas sportsshoes was a particular long, hard and dangerous job!
But.....it was all fun!!!
