Boeing 707

Following a wrong approach configuration, the airplane landed nose gear first on runway 18. Upon impact, a tire burst and the airplane bounced three times before the captain decided to initiate a go-around. After a circuit, the crew completed a second landing safely but after touchdown, control was lost as the nosewheel steering was inoperative. The airplane veered off runway and came to rest. While all three crew members escaped uninjured, the aircraft was written off.

The crew was completing a cargo flight from London to Lusaka with intermediate stops in Athens and Nairobi. Following an uneventful flight from Nairobi, a clearance was given to descend further down to FL70 in 1,000 feet steps. At 09:28 the copilot reported that the airfield was in sight. Lusaka then cleared the aircraft to descend to 6,000 feet (2,221 feet above runway elevation) and moments later a clearance was given to make a visual approach for runway 10. At 09:32 flaps were selected to 50°. Suddenly, at 09:33, the complete right-hand horizontal stabilizer and elevator assembly were seen to separate in flight. The aircraft pitched rapidly nose down and dived vertically into the ground from a height of about 800 feet. The main wreckage was located 3,660 meters from the runway threshold. The aircraft was totally destroyed and all six occupants were killed.

March 17, 1977 was the fourth day of a Boeing 707-436 conversion base training programme at Glasgow-Prestwick Airport (PIK). On the day of the accident the trainee first officer was in the right hand pilot's seat and was flying the first detail. The commander was in the left hand pilot's seat, and the captain under training was acting as flight engineer, being supervised by the fourth crew member, a supervisory first officer who was seated behind the commander. After completing all the necessary checks and the engine starting procedure the commander gave the trainee first officer a comprehensive briefing on cross wind takeoff techniques with reference to the local weather forecast, which gave a surface wind of 190° /18 knots gusting to 35 knots. In particular he emphasised the need for into-wind aileron, demonstrating the amount required, and for opposite rudder. At 08:42 the aircraft was cleared to taxi to runway 13. While taxiing, the 'taxiing checklist' was completed. At the light aircraft weights used for training, standardized takeoff airspeeds were used as follows: V1 - 125 knots, VR - 135 knots and V2 - 145 knots. Based on the prevailing conditions and actual aircraft takeoff weight of 94,580 kg, the true takeoff airspeeds were: V1 - 125 knots, VR - 125 knots and V2 - 142 knots; the VMCG and the VMCA were 125 knots and 119 knots respectively. After receiving ATC clearance, the aircraft entered the active runway from the fast turnoff for runway 31. From this position the takeoff run available was approximately 2,388 metres; the takeoff run required was 1,433 metres. On entering the runway the commander handed over control to the trainee first officer and the aircraft commenced its takeoff run, from a rolling start, shortly after 08:48. The Tower passed a surface wind of 220° /15 knots and the trainee applied about 15° to 20° of into-wind aileron (ie right wing down) and some left rudder. Full power was then applied and the V1 and VR airspeeds were called by the flight engineer. As the aircraft was being rotated to a pitch attitude of 4 1/2° the commander simulated a No. 1 engine failure by retarding the appropriate thrust lever, and calling out "number one engine's failed." After the aircraft became airborne it climbed away in a normal manner to a height of approximately 20 to 30 feet when suddenly the left wing dropped about 20° and the No. 1 engine nacelle struck the left edge of the runway. The aircraft then began to yaw and roll to the right and to sink to the ground. The yaw/roll continued until No. 4 nacelle struck the runway and the aircraft then tracked sideways down the runway, with the engines and other parts of the structure breaking away and the landing gear collapsing. It came to a stop almost at the intersection of runway 03/21. The distance from the start of the takeoff roll to this point was approximately 2,230 metres. A fire erupted. The external fire was rapidly dealt with but the internal fire was not extinguished for some 50 minutes.

Following an uneventful flight from Bombay, the crew started the descent to Bangkok-Don Mueang Airport by night. On approach, the pilot reported runway in sight and was cleared to land on runway 21L. On short final, he failed to realize his altitude was too low when the four engine airplane struck the roof of a building and crashed in flames on a spinning factory located 2 km short of runway. The aircraft and several buildings were killed. All 53 occupants on board the B707 were killed as well as 20 people working in the factory. At the time of the accident, the visibility was estimated to be 4 km.

After a long takeoff roll, the airplane took off from runway 32 but encountered serious difficulties to gain sufficient height. After liftoff, the airplane continued at a height of about six metres then struck successively trees, houses and power cables before crashing in a huge explosion on a soccer field located about 560 metres past the runway end. The aircraft disintegrated on impact and several houses and buildings were destroyed. All three crew members were killed as well as 110 people on the ground. 32 others were injured, most of them seriously. Weather conditions at the time of the accident were considered as marginal but did not contribute to the mishap.

After takeoff from runway 29 at Tehran-Mehrabad Airport, while climbing in limited visibility, the four engine airplane drifted to the right instead of making a left turn as mentioned in the Standard Instrument Procedures for OIII Airport Runway 29. At an altitude of 6,500 feet, the airplane struck the slope of a mountain (2,020 metres high) located 17 km northwest of the airport. The aircraft disintegrated on impact and all five occupants have been killed.

The approach to Milan-Malpensa Airport was completed in limited visibility due to foggy conditions. During the last segment, the airplane struck the ground to the left of the main runway. On impact, all landing gears and all four engines were torn off. The aircraft slid for few hundred meters then came to rest in a grassy area with the fuselage bent and the cockpit that separated from the rest of the aircraft. All 122 occupants were evacuated, 26 of them were injured, among them the Italian tenor Luciano Pavarotti.

On behalf of Royal Air Maroc, the aircraft was completing a charter flight from Paris-Le Bourget to Agadir, carrying 181 Moroccan workers and their family members back for holidays. Following an uneventful flight, the crew contacted ATC and was cleared to start the descent. At an altitude of 2,400 feet, the right wing struck a rocky peak. On impact, the engine n°4 was torn off. The crew increased engine power and the airplane flew for about 400 meters before it disintegrated in a small valley. The wreckage was found few hours later about 40 km north of Agadir-Inezgane Airport. None of the 188 occupants survived the crash.

The four engine airplane departed Athens-Ellinikon Airport at 1112LT on a flight to Rome, last leg before the transatlantic flight to New York. While cruising at an altitude of 28,000 feet, the airplane went out of control, entered a steep dive and crashed into the Ionian Sea bout 80 km west of Kefalonia Island, Greece. Some debris were found floating on water and no survivor was found among the 88 occupants.

Following an uneventful flight from Hong Kong-Kai Tak, the crew started the descent to Denpasa-Ngurah Rai Airport by night and limited visibility. While descending to runway 09 at an altitude of 4,000 feet, the airplane initiated a turn to 263° when it struck the slope of Mt Masehe located about 68 km from the airport. The wreckage was found few hours later. The aircraft was totally destroyed upon impact and all 107 occupants have been killed.
