Investigators will consider the weather conditions, as well as the possibility of human error or an aircraft malfunction as they try to determine why a Delta Air Lines jet burst into flames and flipped upside down as it tried to land in Toronto, aviation experts said Tuesday.Witnesses and video from the scene Monday afternoon shows the plane landing so hard that its right wing is sheared off. It bursts into flames before sliding down the runway and flipping over. Miraculously, all 80 people on board the flight from Minneapolis to Toronto바카라 게임 웹사이트�s Pearson International Airport survived.바카라 게임 웹사이트�It appears from the video that the plane landed so hard that the right main gear collapsed. The tail and right wing began skidding causing the plane to roll over to the right,바카라 게임 웹사이트� Ella Atkins, the head of Virginia Tech바카라 게임 웹사이트�s aerospace and ocean engineering department and a pilot. 바카라 게임 웹사이트�During the rollover, the right wing and tail sheared off, and a fire ignited, likely due to skidding and fuel leakage at least from a right wing tank.바카라 게임 웹사이트�All but two of the 21 people injured on the flight have been released from hospitals, the airport CEO said Tuesday.바카라 게임 웹사이트�How grateful we are there was no loss of life or life threatening injuries," Deborah Flint, CEO of Greater Toronto Airports Authority, said during a news conference. 바카라 게임 웹사이트�The crew heroically led passengers to safety.바카라 게임 웹사이트� Crash investigationCommunications between the tower and pilot were normal on approach and it바카라 게임 웹사이트�s not clear what went wrong when the plane 바카라 게임 웹사이트� a Mitsubishi CRJ-900 made by the Canadian company Bombardier 바카라 게임 웹사이트� touched down.Aviation experts said investigators will consider conditions on the ground, the pilot's actions before landing, and potential problems with the landing gear. The Transportation Safety Board of Canada is leading the investigation with support from the U.S. National Transportation Safety Board.Video below: Investigators will review aircraft for next 48 hoursJuan Browne, a commercial pilot who discusses aviation incidents on his popular YouTube channel, said preliminary data suggests the speed and rate of descent, crosswinds and the weather were "within limits.바카라 게임 웹사이트�But Browne raised concerns about the pilots' actions before landing.바카라 게임 웹사이트�It appears that the aircraft simply did not flare at all,바카라 게임 웹사이트� Browne said. Flaring slows the aircraft바카라 게임 웹사이트�s rate of descent. 바카라 게임 웹사이트�They just drove it into the runway.바카라 게임 웹사이트�At the time of the crash, Pearson was experiencing blowing snow and winds of 32 mph (51 kph) gusting to 40 mph, according to the Meteorological Service of Canada. The temperature was about 16.5 degrees Fahrenheit. Browne said blowing snow reduces visibility.Michael McCormick, an assistant professor and program coordinator for air traffic management at Embry-Riddle Aeronautical University in Daytona Beach, Florida, said investigators would look closely at the landing gear to make sure it was properly locked in place, and would consider staffing on the ground and in the aircraft.바카라 게임 웹사이트�They will look at the number of people working both on the aircraft and the control towers. And they will look at their schedules," McCormick said. "Are they well rested? Are they well staffed?바카라 게임 웹사이트�But a Canadian investigator refused to comment on preliminary theories.바카라 게임 웹사이트�At this point, it바카라 게임 웹사이트�s far too early to say what the cause of this accident might be,바카라 게임 웹사이트� TSB Senior Investigator Ken Webster said in a video statement Tuesday as he stood near the remains of the aircraft.He said investigators will examine the wreckage and runway, and have removed the cockpit voice and flight data recorders and sent them to the lab for analysis.바카라 게임 웹사이트�Everything just kind of went sideways바카라 게임 웹사이트�Peter Carlson, who was traveling to Toronto for a paramedics conference, said the landing was 바카라 게임 웹사이트�very forceful.바카라 게임 웹사이트�바카라 게임 웹사이트�All the sudden everything just kind of went sideways and the next thing I know, it바카라 게임 웹사이트�s kind of a blink and I바카라 게임 웹사이트�m upside down still strapped in,바카라 게임 웹사이트� he told CBC 온라인 바카라 게임.Video below shows passenger evacuating overturned Delta flightThat everyone survived the Delta crash is a testament to the safety improvements made by airlines and aircraft manufacturers, including wings that are designed to come off to reduce explosions, well-trained flight crews and seats built to withstand impacts of up to 16 times the force of gravity.바카라 게임 웹사이트�That seat is your single best resource in order to keep you protected,바카라 게임 웹사이트� McCormick said. 바카라 게임 웹사이트�There바카라 게임 웹사이트�s a reason why the flight attendants walk around the aircraft prior to (landing) ... to make sure everybody has their seat belts fastened." But is it safe to fly?The crash was the fourth major aviation accident in North America in recent weeks. A commercial jetliner and an Army helicopter collided near Reagan National Airport in Washington, D.C., on Jan. 29, killing 67 people. A medical transportation plane crashed in Philadelphia on Jan. 31, killing the six people on board and another person on the ground. And on Feb. 6, 10 people were killed in a plane crash in Alaska.Nevertheless, according to Jeff Guzzetti, an airline safety consultant and a former FAA and NTSB investigator, air travel is 바카라 게임 웹사이트�extremely safe."바카라 게임 웹사이트�The odds of getting injured or killed in an commercial airline accident is far less than driving in your car,바카라 게임 웹사이트� Guzzetti said.Still, he worries about layoffs at the Federal Aviation Administration under the Trump administration. 바카라 게임 웹사이트�I am concerned that the proposed cuts and changes to the FAA may increase the risk of further accidents,바카라 게임 웹사이트� he said.The Delta flight was cleared to land at about 2:10 p.m. Audio recordings show the control tower warned the pilots of a possible air flow 바카라 게임 웹사이트�bump바카라 게임 웹사이트� on approach.바카라 게임 웹사이트�It was windy, but the airplanes are designed and certified to handle that,바카라 게임 웹사이트� said John Cox, CEO of aviation safety consulting firm Safety Operating Systems in St. Petersburg, Florida. 바카라 게임 웹사이트�The pilots are trained and experienced to handle that.바카라 게임 웹사이트�Carlson said when he took off his seat belt he crashed onto the ceiling, which had become the floor. He smelled gas, saw aviation fuel cascading down the cabin windows and knew they all had to get out. Carlson and another man assisted a mother and her son out of the plane, then Carlson dropped onto the snowy tarmac."All of us just wanted to be out of the aircraft,바카라 게임 웹사이트� he said.
