The pilot of a P-51 Mustang killed in a Reno air race crash said major changes were made to the World War II-era fighter plane before this year's race.
A podcast uploaded to YouTube in June shows Jimmy Leeward discussing the plane called "The Galloping Ghost."
He said his crew cut five feet off each wing and shortened the ailerons _ the back edge of the main wings used to control balance. Leeward said the team also took the scoop off the bottom, changed the cooling system and put on a different canopy.
He said the goal was to make the plane more aerodynamic so it goes faster without a bigger engine.
Leeward said the systems weren't proven, but the team thought they would be OK.
