Flight 658 was boarded and preparing to take off when a warning light came on. Jet in question cleared to fly againThe jet in question has already been cleared and is on track for its next flight on Sunday. WestJet grounded its fleet of Max jets like most airlines around the world did until earlier this month, when flight authorities cleared the jets for takeoff again. The flight would have been the jet in question's first flight since being approved for use again, and only the third Max flight at WestJet overall since reintroduction this week.
