Why are officials warning of prolonged travel delays following the Delta Flight 4819 crash in Toronto?

Officials are warning travelers to expect delays and cancellations that could last for days following Delta Flight 4819's crash landing in Toronto. This extended disruption is compounded by the fact that the airport was already experiencing a significant backlog of flights before the incident occurred, primarily due to successive winter storms affecting operations. The crash has further exacerbated an already strained situation at the airport, creating additional complications for air traffic management and scheduling. With the combined impact of pre-existing weather-related backups and the aftermath of the crash, airport authorities anticipate that travel disruptions will continue for an extended period.
