ADDIS ABABA: Two pilots fell asleep and missed their landing during a flight from Sudan to Ethiopia, a report said.

The incident took place onboard an Ethiopian Airlines Boeing 737-800 enroute from Khartoum to Addis Ababa. According to the report, the aircraft was cruising at 37,000 feet on autopilot when it failed to descend at Addis Ababa Bole International Airport, its scheduled destination, on August 15.

Air traffic control were apparently unable to reach the crew despite making several attempts at contact. However, an alarm was triggered when the plane overshot the runway and continued along the route, the report said.

The aircraft subsequently began to descend, landing safely around 25 minutes later.

Automatic Dependent Surveillance-Broadcast (ADS-B) data shows the aircraft overflying the runway, before beginning its descent and manoeuvring for another approach.
