President Barack Obama’s 19 minute speech at Nelson Mandela’s memorial cost taxpayers at least $5 million.
That’s not counting any cakes and coffee he and his inner circle consume aboard Air Force One  during the 18,000-mile round trip to Johannesburg, via Dakar, in Senegal.
The 28-hour two-way flight to the memorial will cost $5 million because the four-engined Boeing 747 costs roughly $180,000 an hour to operate, according to a May 2012 report  by the Congressional Research Service.
The cost includes jet fuel and subsequent maintenance of the aircraft’s engines, electronics and hotel-class facilities.
