During testing the jettisonable main landing gear arrangement proved to be a serious problem and caused many planes to be damaged at take-off when the wheels rebounded and crashed into the plane. Malfunctioning hydraulic dampers in the skid could lead to back injuries for the pilot on landing , and the airplane lacked steering or braking control during the landing run, leaving the pilot unable to avoid obstacles. Once on the ground, it had to be retrieved by a specialized tractor-like vehicle as the Komet was unpowered and lacked wheels at this point.
