What are the potential causes of the Delta plane crash at Toronto's Pearson Airport?

The crash likely resulted from multiple factors. Transportation correspondent Sam Sweeney explains it could be a maintenance issue or weather-related, noting winds over 40 miles per hour, snow, and ice at the time. The investigation will benefit from surveillance cameras capturing the incident and interviews with the pilots. The National Transportation Safety Board from the United States will assist Canada's Transportation Safety Board in piecing together what happened. All 80 passengers and crew survived, allowing investigators to gather firsthand accounts as they determine the exact cause.
