Everyone focuses on the Presidential aircraft–and forgets that it is NOT just “Air Force One”–they forget about the “chase” transports for the rest of the staff–the jets that transport the guards–the aircraft that transport the Presidential limo and the other vehicles required–and all of the transportation on smaller aircraft for the hordes of people required to do the legwork for a Presidential trip.
Forget the “dog and pony show” and save literally TONS of fuel for all of the staff and guards required by Presidential travel these days.
The argument over “heat load” and associated fuel costs is literally a “drop in the bucket” of fuel used.
