Japan Airlines Co.’s airplane had a radio malfunction during a flight from Haneda Airport to New Chitose Airport on Thursday. The aircraft landed safely by relying on light gun signals sent by the air traffic controller at New Chitose Airport.

The 207 passengers on board were not injured.

According to the company, JAL Flight 521 took off from Haneda Airport at around 4 p.m. on the day. When the frequency was switched to the New Chitose Airport control area at around 4:50 p.m., it was found that the aircraft could not communicate by radio.
