US Probe: Controller Missed Pilot Error in Hudson River Midair Collision Olcay Rached 28 April 2010 The wreckage of a helicopter is lifted by crane from the Hudson River and placed on a boat as seen from Hoboken, New Jersey (File Photo - 09 Aug 2009) Photo: AP The wreckage of a helicopter is lifted by crane from the Hudson River and placed on a boat as seen from Hoboken, New Jersey (File Photo - 09 Aug 2009) A U.S. government probe into the deadly 2009 midair collision near New York City says an air traffic controller missed a key pilot error just before the accident. The National Transportation Safety Board released documents Wednesday showing a controller at the Teterboro Airport in New Jersey had been in contact with the pilot of a small plane involved in the August 8, 2009 crash. The report found that the controller was also monitoring two other conversations - including a personal phone call - at the time and did not hear the pilot incorrectly repeat a radio frequency for the control tower at the airport. Shortly after, the plane collided with a sightseeing helicopter and both aircraft plunged into the Hudson River. Nine people onboard the two aircraft were killed. Five Italian tourists plus the pilot were on the helicopter. Two passengers and a pilot were in the single-engine plane. Some information for this report was provided by AP. .
