The Air Force says a South Carolina-based fighter jet that crash landed in South Korea this summer did so because its landing gear collapsed immediately after touching down. The Air Force says the F-16C Falcon skidded off the runway, flipped and rolled over shortly after touching down during the July crash. The pilot suffered a minor back injury. The Air Force values the plane’s loss at $33.5 million. Details of the crash were released Tuesday in an accident investigation report conducted by Air Combat Command in Virginia. The plane and the pilot belonged to the 55th Fighter Squadron based at Shaw Air Force Base, S.C. The Air Force says when the crash occurred, the pilot was returning from a routine training mission to Osan Air Base.
