Lt. Cmdr. Eric "Magic" Buus flew the F-35C for two hours, checking instruments that will measure structural loads on the airframe during flight maneuvers. The F-35C is distinct from the F-35A and F-35B variants with larger wing surfaces and reinforced landing gear for greater control when operating in the demanding carrier take-off and landing environment.
