Mr. Obama will make the familiar walk across to the South Lawn to one of the VH-3D Sirkorsky Sea King helicopters that serve as Marine One. He'll take the ten minute flight to Andrews Air Force Base, where he'll board the most recognized aircraft in the world: Air Force One.
There are two 747s that most frequently serve as the presidential aircraft – they are identical except for their tail numbers: 28000 and 29000. But there are other aircraft assigned to the Presidential Airlift Group including 757s and Gulfstream IIIs. There have been a few occasions when even a C-17 cargo plane has been used as Air Force One too.
And though the 747s are magnificent aircraft with extraordinary capabilities, the planes have been in service since 1990 – and the Air Force last month put out the word to defense contractors to start planning for the job of building 3 new jumbo jets for presidential use - ready for delivery in the year 2017. Lockheed Martin already has the Navy contract to build a new fleet of helicopters for HMX-1 – the U.S. Marine Corps unit that operates and maintains the choppers that serve as Marine One.
With the new president comes a new pilot. Col. Scott Turner takes over the prestigious job of flying the president from Col. Mark Tillman, who was President Bush's pilot for the last eight years. And when a new President takes his first ride aboard Air Force One – all aboard receive a certificate signed by the pilot – certifying their presence aboard the Inaugural Flight. It's a great souvenir.
