What was unusual about the Delta Air Lines plane crash at Toronto Pearson Airport?

The most surprising aspect was the lack of warning before the incident occurred. Despite clear communications between the control tower and pilot during landing, there was no indication of trouble before the aircraft suddenly toppled sideways and flipped over. The CRJ900LR aircraft touched down normally before the unexpected accident occurred. Despite the dramatic nature of the crash, where the plane ended upside down with flames that required firefighters' intervention, all 80 passengers survived with minor injuries. The incident could have been far more devastating and led to loss of lives, making it a remarkable case of survival in what marks the fourth major aviation accident in North America within just three weeks.
