Many years back working as a transportation and distribution supervisor for a very large company this poster had opportunities to visit and evaluate cargo companies. One of them was Flying Tigers, who had recently at that time acquired 747 cargo aircraft. Flying Tigers was bought by FedEx in 1988. During a visit at FT's Boston's Logan facility this supervisor has the chance to view the empty interior of one of the 747's. The FT sales director mentioned it was costing them US$ 25,000 hour to operate the aircraft, that included all costs. This empty plane sitting idle, during this poster's 3 hr visit ate up US$ 75,000 while making no revenue. A Google search for "how much does it cost an hour to operate a large air cargo planes" was done and the result was $28,744. It is obvious operating costs have gone up from the $25,000 mentioned many years ago to this poster. It would be reasonable to think present operating costs are considerably more than $29,000 said in the Google search.
