Check out how many crashes had United since it was founded. And when you done, compare USAir with United. They are about the same age, USAir was founded in 1937 as a All American Aviation, and United was founded six years earlier in 1931( management company for four airlines: Varney Speed Lines, National Air Transport, Pacific Air and Boeing Air Transport)Dont count PSA and Piedmont as a part of USAir, only pure USAir, because they joined USAir in 1988 (PSA),and 1989 (Piedmont). In 60's and 70's United had new DC-8s, they were going down very often. Now it happened to USAir with their new 734, 733. All airlines had (and has) their good and bad time.
