This 2012 photo provided by the National Airline History Museum shows its Lockheed Constellation, or Connie, as the propeller-driven aircraft was known, during engine inspection in Kansas City, Mo. The museum is trying to raise $3.2 million to restore it, the only one left in the U.S. that’s airworthy, and recreate millionaire aviator Howard Hughes’ record-setting cross-country flight in the plane that transformed commercial air travel.
