The Port Authority fire truck involved in a fatal crash with an Air Canada jet landing at LaGuardia Airport did not have transponders installed, which could have helped air traffic controllers better track its movements. The collision occurred around 11:45 p.m. on Sunday, killing two pilots and injuring dozens of passengers. The NTSB is yet to interview the Port Authority Police sergeant and officer involved in the fire truck. The plane's black box was recovered from the wreckage by cutting a hole in the aircraft's roof. The airport was reopened after the crash, but runway four where the crash occurred will remain closed for the foreseeable future.
