What safety protocols helped save lives during the Delta Flight 4819 crash?

Several critical safety protocols likely saved lives during the Delta Flight 4819 crash at Toronto's Pearson Airport. Wearing seatbelts proved essential, as passengers reported hanging upside down by their restraints after the crash, which prevented more serious injuries despite the plane's landing gear collapsing and wing striking the ground. Equally important was passengers' willingness to follow flight attendant instructions, evacuating quickly without retrieving luggage. This rapid evacuation process, combined with proper use of safety restraints, contributed significantly to the survival of all 80 people on board despite 21 injuries. These basic yet vital safety measures underscore why airline safety briefings should never be ignored.
