The National Transportation Safety Board (NTSB) said late on the 12th that the helicopter that crashed into the Hudson River in New York City on the 10th lacked a flight recorder, and no equipment on board recorded information that would help the investigation. It is understood that New York City Police Department divers are continuing to search for parts of the helicopter, including the main rotor, gearbox, tail rotor and tail boom. Federal investigators said that the passengers on the crashed helicopter included a senior executive of a Siemens subsidiary, his wife and their three children, and all five were killed. It is reported that the crashed helicopter underwent its last major inspection on March 1 and completed seven flights before the accident.
