The 747-200 Isn't good enough for the air force and president anymore... But the fleet of planes now used to transport President Obama -- two highly customized Boeing 747-200B series aircraft -- is aging. The first of the current aircraft were delivered 20 years ago during the administration of President George H. W. Bush. Rep. Todd Tiahrt, R-Kan., a member of the committee and a former aerospace executive, noted that there are fewer than 20 747-200s -- the commercial model Air Force One is based on -- still in service. Tiarht said the president's aircraft is nearing a point where the operation and support costs will exceed the value of the existing planes. www.foxnews.com/politics/2010/03/24/pentagon-develops-plan-buy-new-air-force-fleet/
