Transport Canada has deployed investigators to the scene of a plane crash in Seguin Township. The identities will not be confirmed until a post mortem has been completed at the Chief Coroner’s office in Toronto. Two bodies have been confirmed to be at the location of the site. During these later stages of the flight, it slowed somewhat, according to the preliminary review.The West Parry Sound Ontario Provincial Police (OPP) and the Transport Canada Safety Board (TCSB) have concluded their investigation into the plane crash site. The last data transmission captured by Flightradar24 occurred at about 3200 feet altitude.Ībout 40 seconds before the last transmission, the jet stopped descending and briefly climbed before resuming the dive. While unverified videos showed the plane diving at a steep angle near the ground, it wasn’t clear how fast it was travelling at impact. The Bloomberg review was conservative and actual speeds may be higher. The speed estimates were based on how fast the jet travelled between two points and didn’t take into account wind direction or other atmospheric conditions. Bloomberg’s computations give a rough idea of how fast it was flying through the air by taking into account its horizontal speed over the ground as well as how fast it was descending. If it isn’t available for some reason, aerodynamic experts can perform extensive analysis to more closely estimate speed.įlightradar24’s data includes the jet’s speed, but it’s measured horizontally across the ground. Modern black-box recorders, which store data on computer chips, have a good record of survival in high-velocity crashes, said James Cash, who formerly served as the US National Transportation Safety Board’s chief technical adviser for recorders.Īccident investigators should be able to find more precise speed data from the jet’s flight recorder. Do the flight data recorder or cockpit voice recorder or quick access recorder - do any survive? I just don’t know the answer.” “It looks like it literally evaporated into a crater. “It was an exceedingly high-energy crash,” said Bob Mann, president of RW Mann & Co consultancy, who did not participate in the speed analysis. The speed data is consistent with videos appearing to show the jet diving at a steep angle in the moments before impact and indicates that it likely hit the ground with huge force. The jetliner was cruising at about 957km/h before the dive.

Video footage run by China’s CCTV showed debris marked by numbers at the site of the crash. Sound travels at 1235km/h at sea level but slows with altitude as air temperature goes down and is about 1067km/h at 35,000 feet (10,668 metres). “The preliminary data indicate it was near the speed of sound,” said John Hansman, a Massachusetts Institute of Technology astronautics and aeronautics professor who reviewed Bloomberg’s calculation of the jet’s speed. 737-800 was knifing through the air at more than 966km/h, and at times may have exceeded 1100km/h, according to data from Flightradar24, a website that tracks planes. The Boeing 737-800 was travelling at close to the speed of sound in the moments before it slammed into a hillside, according to a Bloomberg News review of flight-track data. Mao said the captain had 6000 flying hours, the first co-pilot 31,700 hours and the second co-pilot 550 hours. The plane had also met all maintenance requirements. He said weather conditions were normal and that all three flight crew were “well behaved and had relatively harmonious” family lives and were in good health with valid flying certificates.
