Tradewinds was bought by Centurion, a DC-10 outfit out of Miami. I learned this from a former check airman for Centurion.
Everyone is right about the classic. Too much gas, too many cycles, and maintenance cost going through the roof and FAR part 26. Too bad, but even the great ones meet their maker with age. I am sure they will make great beer cans.
The 777F is the future of air cargo, sips gas and has close to the cubic space and weight capabilities of the 747-800 when it comes out.
