It's ridiculously expensive to fly Air Force One
The FY15 cost per flying hour for Air Force One (VC-25A) includes "fuel, flight consumables, depot level repairables, aircraft overhaul, and engine overhaul," according to the letter from the Department of the Air Force Headquarters Air Mobility Command to Judicial Watch.
According to the National Taxpayer Union Foundation, President Barack Obama has traveled internationally more than any other president, and he has done it on the "most expensive-to-operate Air Force One to date."
The aging Air Force One and it's twin decoy will be replaced with two Boeing's 747-8 and are expected to be operational in 2020.
