Peter Carlson, who was traveling to Toronto for a paramedics
conference, said the landing was "very forceful."

"All the sudden everything just kind of went sideways and the next
thing I know, it's kind of a blink and I'm upside down still strapped
in," he told CBC News.

Juan 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."

But Browne raised concerns about the pilots' actions before landing.

"It appears that the aircraft simply did not flare at all," Browne
said. Flaring slows the aircraft's rate of descent. "They just drove
it into the runway."
