After touchdown on a wet runway at Santiago de Compostela Airport, the crew activated the thrust reverser systems and started the braking procedure. Unable to stop within the remaining distance, the airplane overran, lost its undercarriage and came to rest in flames in a wooded area, broken in two. All 223 occupants were evacuated, 52 of them were injured, some seriously. The aircraft was destroyed.

The airplane was completing a charter flight from Brussels to Tenerife, carrying 189 passengers and a crew of nine on behalf of Sebelair. On approach to Tenerife-Norte-Los Rodeos Airport, the crew informed ATC about technical problems as he was unable to lower the nose gear. The landing was completed on runway 12/30 with the nose gear retracted and the airplane slid for a distance of 1,200 meters before coming to rest in flames. All 198 occupants were evacuated, four passengers were slightly injured. The aircraft was destroyed by fire.

The four engine airplane departed Lajes Airport, Azores Islands, at 0836LT on a maritime patrol flight. About two hours later, the crew reported his position and that all went well on board. This was the last radio transmission. At 1120LT, while cruising at an altitude of 2,300 feet in a limited visibility due to foggy conditions, the airplane struck the slope of a mountain (5,200 feet high) at a speed pof 220 knots and crashed. The wreckage was found in a wooded area located near la Frontera, in the center of the island. At the time of the accident, three engines were operating while the engine n°1 was shutdown for loiter.

The airplane departed Madrid-Cuatro Vientos Airport in the early morning on a flight to Bournemouth-Hurn, Dorset, with an intermediate stop in Burgos. While flying under VFR mode in adverse weather conditions, the airplane struck the slope of a mountain located near Guadarrama, about 50 km northwest of Cuatro Vientos Airport. The wreckage was found near the Puerto de los Leones Pass and all four occupants were killed.

The crew was returning to Jerez de la Frontera Airport following a night training mission when the airplane crashed on final approach for unknown reasons. Four crew members were injured while six others were killed.

The crew attempted to land on rough sea due to high winds. The seaplane struck high waves and crashed. All three crew members were rescued.

The KLM Boeing 747, registration PH-BUF, took off from Schipol Airport (Amsterdam) at 0900 hours on 27 March 1977, en route to Las Palmas de Gran Canaria. This flight was part of the Charter Series KL4805/4806 Amsterdam-Las Palmas (Canary Islands) - Amsterdam operated by KLM on behalf of the Holland International Travel Group (H.I.N.T.), Rijswijk-Z.H. The Boeing 747 registration N736PA, flight number 1736, left Los Angeles International Airport, California, United States, on 26 March 1977, local date, at 0129Z hours, arriving at John F. Kennedy International Airport at 0617Z hours. After the aeroplane was refuelled and a crew change effected, it took off for Las Palmas de Gran Canaria (Spain) at 0742Z. While the aeroplanes were en route to Las Palmas, a bomb exploded in the airport passenger terminal. On account of this incident and of a warning regarding a possible second bomb, the airport was closed. Therefore, KLM 4805 was diverted to Los Rodeos (Tenerife) Airport, arriving at 1338Z on 27 March 1977. For the same reason, PAA1736 proceeded to the same airport, which was its alternate, landing at 1415. At first the KLM passengers were not allowed to leave the aeroplane, but after about twenty minutes they were all transported to the terminal building by bus. On alighting from the bus, they received cards identifying them as passengers in transit on Flight KL 4805. Later, all the passengers boarded KLM 4805 expect the H.I.N.T. Company guide, who remained in Tenerife. When Las Palmas Airport was opened to traffic once more, the PAA 1736 crew prepared to proceed to Las Palmas, which was the flight's planned destination. When they attempted to taxi on the taxiway leading to runway 12, where they had been parked with four other aeroplanes on account of the congestion caused by the number of flights diverted to Tenerife, they discovered that it was blocked by KLM Boeing 747, Flight 4805, which was located between PAA 1736 and the entrance to the active runway. The first officer and the flight engineer left the aeroplane and measured the clearance left by the KLM aircraft, reaching the conclusion that it was insufficient to allow PAA 1736 to pass by, obliging them to writ until the former had started to taxi. The passengers of PAA 1736 did not leave the aeroplane during the whole time that it remained in the airport. KLM 4805 called the tower at 1656 requesting permission to taxi. It was authorized to do so and at 1658 requested to backtrack on runway 12 for take-off on runway 30. The tower controller first cleared the KLM flight to taxi to the holding position for runway 30 by taxiing down the main runway and leaving it by the (third) taxiway to its left. KLM 4805 acknowledged receipt of this message from the tower, stating that it was at that moment taxiing on the runway, which it would leave by the first taxiway in order to proceed to the approach end of runway 30. The tower controller immediately issued an amended clearance, instructing it to continue to taxi to the end of the runway, where it should proceed to backtrack. The KLM flight confirmed that it had received the message, that it would backtrack, and that it was taxiing down tile main runway. The tower signalled its approval, whereupon KLM 4805 immediately asked the tower again if what they had asked it to do was to turn left on taxiway one. The tower replied in the negative and repeated that it should continue on to the end of the runway and there backtrack. Finally, at 1659, KLM 4805 replied, "O.K., sir." At 1702, the PAA aeroplane called the tower to request confirmation that it should taxi down the runway. The tower controller confirmed this, also adding that they should leave the runway by the third taxiway to their left. At 1703:00, in reply to the tower controller's query to KLM 4805 as to how many runway exits they had passed, the latter confirmed that at that moment they were passing by taxiway C4. The tower controller told KLM 4805, "O.K., at the end of the runway make one eighty and report ready for ATC clearance ." In response to a query from KLM 4805, the tower controller advised both aeroplanes - KLM 4805 and PAA 1736 - that the runway centre line lights were out of service. The controller also reiterated to PAA 1736 that they were to leave the main runway via the third taxiway to their left and that they should report leaving the runway. At the times indicated, the following conversations took place between the tower and the KLM 4805 and PAA 1736 aeroplanes. Times taken from KLM CVR.
1705:44.6 KLM 4805: The KLM four eight zero five is now ready for take-off and we are waiting for our ATC clearance. (1705:50.77).
1705:53.41 Tower: KLM eight seven zero five you are cleared to the Papa Beacon, climb to and maintain flight level nine zero, right turn after take-off, proceed with heading four zero until intercepting the three two five radial from Las Palmas VOR. (1706 :08.09).
1706:09.61 KLM 4805: Ah - Roger, sir, we are cleared to the Papa Beacon, flight level nine zero until intercepting the three two five. We are now (at take-off). (1706:17.79).
1706:18.19 Tower : O.K..... Stand by for take-off, I will call you. (1706: 21.79).
Note: A squeal starts at: 1706:19.39 The squeal ends at: 1706:22.06
1706:21.92 PAA 1736: Clipper one seven three six. (1706 : 23.39).
1706:25.47 Tower: Ah - Papa Alpha one seven three six report the runway clear. (1706: 28.89).
1706:29.59 PAA 1736: O.K., will report when we're clear. (1706:30.69).
1706:31.69 Tower: Thank you.
Subsequently, KLM 4805, which had released its brakes to start take-off run 20 seconds before this communication took place, collided with the PAA aeroplane. The control tower received no further communications from PAA 1736, nor from KLM 4805. There were no eyewitnesses to the collision. All 248 occupants on board the KLM 747 were killed. Among the 396 people on board the Pan Am 747, 335 were killed (among them nine crew members) and 61 others were injured.

While taxiing on rough water, the airplane struck rocks and came to rest partially submerged. All three crew members were rescued while the aircraft was damaged beyond repair.

The twin engine airplane departed Getafe Airbase in the evening on a liaison flight to Valencia. While approaching Valencia Airport by night and limited visibility, the airplane struck the slope of a mountain located near Chiva, about 20 km west of the airport. The wreckage was found the following day and all 11 occupants were killed.
