South Texas motorists use sledgehammers, shovels to rescue survivors of fiery plane crash

Loop 20 remains heavily closed as federal investigators take over the scene; airport officials say a pre-crash mechanical failure is suspected, though the official cause is still under investigation. The six-passenger twin-engine jet was a Cessna Citation Latitude operated by NetJets, and it went down Tuesday night onto Loop 20 near the Texas-Mexico border. The aircraft was en route from Los Cabos, Mexico to Austin. Dramatic bystander footage shows people rushing to help as the jet burns, with five survivors evacuated and five responders treated for smoke inhalation. Investigators will review flight data and wreckage to determine why the crash occurred.
