The Pentagon has ordered a temporary grounding of the Marine Corps version of Lockheed Martin's (LMT -0.5%) F-35 fighter jet after an incident during a training flight at Eglin Air Force Base in Florida on Wednesday. It ordered the grounding after a propulsion line associated with the B-model's exhaust system failed prior to takeoff. The pilot aborted the takeoff without incident and cleared the runway.
