On May 14, a netizen posted that he took the 13th Lion Air flight SL961 from Jinan to Bangkok, Thailand. Shortly after taking off, he heard a loud noise from the plane. Then the plane returned and landed safely in Jinan. The video shows that on the way back, the crew will notify the passengers through the broadcast, and if a fire or explosion is found, please notify the crew. The Travel Horizon App showed that the flight took off at 23:11 and landed at 23:45. The flight cancellation certificate issued by the airline company provided by a passenger shows that the flight was cancelled due to bird strike.
