An Air India Boeing 787-8 aircraft departed from London and completed a 10-hour flight to Bengaluru despite the pilot encountering a fuel control switch malfunction during engine start. This indicates a decision was made to proceed with a long-haul international flight even after a critical cockpit control exhibited abnormal behaviour before takeoff, and less than a year after a Boeing 787 Dreamliner crash near Ahmedabad caused by a similar issue.
