The burning fuselage of an F/A-18 Hornet lies smoldering after crashing into a residential building in Virginia Beach, Va., Friday, April 6, 2012. The Navy did not immediately return telephone messages left by The Associated Press, but media reports indicate the two aviators were able to eject from the jet before it crashed. They were being treated for injuries that were not considered life threatening.

VIRGINIA BEACH, Va. — The Navy says a rare dual-engine malfunction caused one of its jets to lose thrust and crash into a Virginia Beach apartment complex.

The F/A-18D Hornet crashed on April 6 about 70 seconds after taking off from Naval Air Station Oceana. No one was killed, but the impact or fire from the crash destroyed 27 apartments and injured seven.

The commander of Naval Air Force Atlantic, Rear Adm. Ted Branch, released details of the jet crash investigation during a news conference at Naval Air Station Oceana on Monday.

Branch says the jet's two-man crew ejected at the last second possible to survive, 50 feet above the ground.

The investigation says no disciplinary action against the pilots is warranted.
