An emergency slide on a British Airways Boeing 787 aircraft accidentally deployed in Montreal, Canada, while the plane was being loaded with catering supplies. The incident happened as a Newrest catering truck was unloading at the aircraft’s rear door. According to aviation news site Fl380, the deployment caused a two-and-a-half-hour delay while maintenance crews worked to reset the slide and ensure the aircraft’s door was safe for travel. Emergency slides are designed to inflate rapidly in case of an emergency evacuation, but once deployed, they can take several hours to be retracted and returned to their normal position. This process requires specialized equipment and trained personnel, which contributed to the extended delay at the airport. The affected flight was originally scheduled to depart Montreal for Newark, New Jersey, but the incident caused the flight to be postponed. As a result of the delay, the subsequent flight to Newark, which was to be operated by the same aircraft, was also postponed. No injuries were reported, and the situation was contained without any safety concerns. British Airways described the incident as a technical error and clarified that it did not indicate any broader issues with the aircraft’s safety or reliability. A spokesperson for the airline expressed regret over the inconvenience caused to passengers and confirmed that their teams worked diligently to minimize the delay and get passengers on their way as soon as possible. The airline emphasized its commitment to passenger safety and operational efficiency, and noted that such incidents, while rare, are typically resolved without long-term consequences.
