WHALE 05 was scheduled for take off from Jeddah at 17:24 local time and climbed to 25,000 feet (7,600 m) to perform an aerial refueling. Another Boeing KC-135 took off at around the same time and was supposed to fly the same route. The co-pilot of the second aircraft, ascended to the planned altitude of 25,000 feet (7,600 m). After reaching the target altitude, autopilot was engaged, and the aircraft was about one nautical mile behind the other KC-135.[3]:1
Approximately 45 minutes after takeoff, WHALE 05 encountered forward wake turbulence and suddenly banked more than 110 degrees to the left, and within a few seconds it banked more than 110 degrees to the right.[citation needed] The captain activated the speed brakes and restored the aircraft to a near horizontal position. During the sequence of events, the first and second left wing engines detached from the aircraft.[4][5] After recovery, fire alarms on the two left side engines activated. The captain ordered the boom operator to look at the engines, who reported that there was no fire but that the engines were physically gone.[6] As the aircraft had only been airborne for a short time, it still held almost 31,000 gallons of fuel.[7][8] In addition, the hydraulic reception, fuel pumps, and landing gear were damaged when the engines detached, and fuel was spilling from the left wing.[9][3]:1[2]:106
The aircraft involved, seen here after the emergency landing
To maintain altitude and the speed of fuel discharge, the captain declared "Mayday" and decided to return to Jeddah. The aircraft returned to level flight at 16,000 feet (4,900 m). The pilot soon arrived at Prince Abdullah Air Base an hour and fifteen minutes later. Since the hydraulic system had been damaged, the landing gear was deployed manually. The pilots requested to land on runway 34L because it was the longest runway and had an instrument landing system (ILS) approach.[citation needed] During the landing, the pilot deployed a third engine thrust reverser, but immediately discontinued its use due to difficulty in directional control. Although several tires were damaged, the aircraft landed and came to a stop at about 300 m (1,000 ft) from the end of the runway.[10][3]:1
