The Boeing C-17 is a $250 million aircraft used by the military to transport troops and supplies. Despite the Pentagon asserting it has plenty of C-17s in its fleet, Congress continues to approve funding for additional planes, according to a report by Ben Elgin and Keith Epstein of BusinessWeek. The 2010 budget has $2.5 billion allotted for 10 more C-17's. Curbing the spending is a political quagmire for the Obama Administration because the production of the aircraft provide jobs in 43 states.
