No casualties were made on the Delta Flight, which was upside down at Toronto Airport on Monday evening.
While the investigation into the crash landing is still underway, Sheldon H. Jacobson, a professor at the University of Illinois Urbana-Champaign University, is a professor with over 30 years of experience studying aviation safety and security, and Washington It is just a miracle that told the examiner of the fact that 80 people have surpassed all those who survived.
The plane involved in the crash was the Canadian regional jet model CRJ-900. No casualties have been recorded in more than 100 accidents on CRJ-900 jets since 2005, according to the Aviation Safety Network accident catalog.
“Airplanes are not only designed for efficiency, they are also designed in a very unlikely plane crash crash,” Jacobson told the Washington examiner. “In the end, the structure of the plane allowed all these people to survive. If it (the fuselage) fell, it would turn backwards and start moving down the runway. So, we would have crushed everyone.”
The fuselage can withstand a maximum of several g of force, a measure of acceleration associated with gravity forces, Jacobson said.
But what actually kept passengers safe was the design of the seats that could withstand 16 times the gravity.
“It's designed to keep passengers in their seats, and if there's a sudden change in speed, if you're not buckled, you're a projectile,” Jacobson said.
Another important aspect of seat design is that it can pitch 10 degrees on one side and rotate 10 degrees on the other side to absorb sudden changes in impact and acceleration.
“You're trying to absorb energy,” Jacobson said. “If it gets completely stiff, it's more likely to snap, but if it gives a little more and takes it, it flows a little more.”
In previous aircraft crashes, the FAA found a row of seats stacked in front of the aircraft.
Former FAA safety inspector David Saucy shared with CNN that the wings of planes flying from their fuselage are part of a design to prevent the wings from destroying the aircraft. A similar crash of a plane occurred in 1987, killing 28 people after the wings remained.

“You don't want those wings to tear the fuselage in half,” Sussy told CNN. “The aircraft is slowly stopping and it's supposed to save a lot of lives so I want to make sure it's broken.”
The Toronto plane crash marks North America's fourth major air force accident in less than a month.
