A pilot and co-pilot both fell asleep on an Ethiopian Airlines while flying from Sudan’s Khartoum to Ethiopia capital Addis Ababa and missed the scheduled landing.
The incident took place on Monday, according to Aviation Herald.
The pair did not start the descent even though Air Traffic Control (ATC) raised an alert when flight ET343 approached the airport.
The Boeing 737’s autopilot system kept the plane cruising at 37,000 feet before arrival while the pilots fell asleep, the outlet further said.
The aircraft stayed on the ground for about two-and-a-half hours before departing for its next flight.
Operators tried to contact the pilot and co-pilot several times but failed to make any communication with them.
Later, the autopilot disconnected after overflew the runway where they were supposed to land. That sounded an alarm which woke up the pilots.
The plane then landed safely 25 minutes later and fortunately, no one was harmed, the outlet further said.
Earlier in May, a similar incident was reported on a flight from New York to Rome.
