New Mexico

The takeoff was attempted in strong cross winds. During the takeoff roll, the aircraft deviated from the runway centerline. Despite corrections on part of the flying crew, the four engine aircraft veered off runway and came to rest. A passenger was killed while few others were injured.

Few minutes after its takeoff from Holloman Airport, the aircraft hit a mountain located 10 miles northeast of Alamogordo. All seven crew members were killed.

Flight 260 received an IFR clearance from the tower at 0703 hours: "ATC clears TWA260 for approach at the Santa Fe Airport via Victor 19 climb northbound on the back course of the ILS localiser". The flight departed Albuquerque at 0705 hours. The tower requested the flight to report over-the Weiler Intersection (formerly the Alameda Intersection), however, after taking off there were no further radio contacts with the flight. The aircraft was last seen at an estimated altitude of 3000 feet (8300 feet mean sea level) in a high speed shallow climb continuing its heading towards Sandia Ridge, the upper portion of which was obscured by clouds. The wreckage was sighted the following morning at 9243 feet mean sea level, just below the crest of Sandia Mountain, approximately 13 miles north-east of the Albuquerque Airport and almost directly on a straight line course of 30 degrees magnetic from that airport (elevation 5340 feet mean sea level) to the Santa Fe Airport (elevation 6 344 feet mean sea level). An investigation was initiated by the Civil Aeronautics Board immediately after the accident. This included examination of the wreckage at the crash site which was discontinued because of deep snow and dangerous footing in the mountainous terrain. On May 3, 1955, a second trip was made to the scene of the accident and study of the wreckage was continued. On October 12, 1955, the Board’s Accident Investigation Report was released. The probable cause was determined to have been lack of conformity with prescribed en route procedures and a deviation from airways at an altitude too low to clear obstructions ahead. Because of controversy over certain elements of the report of October 12, 1955, additional study was given to the facts and circumstances of the accident and an amended report thereon was issued by the Board on August 26, 1957. The probable cause of the accident in this report was identical to that of the first report although the analysis portion was altered to revise the statement that the direct course was intentional. On October 10, 1958, the Air Line Pilots Association presented to the Bureau of Safety certain factual information and theories concerning the cause of the accident. On November 24, 1958, a third trip to the accident site was made. While there a new determination was made of the airplane’s heading at the time of impact. Because of these developments since the August 26, 1957, accident report was issued, active investigation and study was resumed. Additional testimony and documentary material were received from representatives of the ALPA, TWA, CAB, Eclipse-Pioneer Division of the Bendix Aviation Corporation, and the Collins Radio Company at Kansas City, Missouri, on January 15 and 16, 1959. In addition, a later study and presentation of facts concerning the instrumentation of the airplane and an analysis of tests made of the fluxgate compass system by Eclipse-Pioneer and ALPA were considered.

Crashed on landing in unknown circumstances. There were no casualties.

While performing a training flight, the aircraft suffered an engine failure. The captain attempted an emergency landing in a desert area located 12 miles south of Caprock. The airplane was damaged beyond repair but there were no casualties.

On landing, the undercarriage collapsed and punctured the fuel tank. The aircraft slid on its belly for dozen yards and came to rest in flames on the runway. All 22 occupants evacuated safely before the aircraft would be destroyed by fire.

While conducting a training mission, the crew encountered mechanical problems and elected to make an emergency landing in a desert area located 12 miles northeast of Hachita, New Mexico. There were no casualties but the aircraft was damaged beyond repair.

Flight 5763, a military contract flight, originated in Oakland, California, with Indiantown Gap, Pennsylvania, as its destination. It was scheduled to depart Oakland, California, at 0200, November 5, 1951, but due to a mechanical delay, departure was not made until 0352. The crew consisted of Captain Alec S. Hamilton, Copilot Henry N. Ingram, and Stewardess Frances B. Reilly. There were 26 passengers on board. The IFR (Instrument Flight Rules) flight plan filed with the CAA prior to departure indicated that the first intended landing would be Albuquerque, New Mexico, with Tucumcari, New Mexico, as the alternate. It showed a cruising altitude of 500 on top and an estimated time of Albuquerque of four hours and five minutes, with six hours and fifteen minutes of fuel on board. At the time of departure the aircraft weighed 38,939 pounds, which was within the allowable gross takeoff weight of 39,900 pounds; the load was properly distributed. The company maintains a dispatching office at Oakland to assist crews in planning flights, but it has no communications facilities for maintaining flight supervision. Company pilots are authorized to act as their own dispatchers, utilizing the CAA Communications facilities for the purpose of flight control. Captain Hamilton stated that prior to departure he was briefed by the U. S. Weather Bureau forecaster at the Oakland Airport on the an route weather and forecasts. Weather information available to the captain at this time indicated that there would be VFR (Visual Flight Rules) flying weather between Oakland and Albuquerque, at a cruising altitude of 11,000 feet, and that helping winds averaging 15 to 20 knots could be expected along the entire route. The forecast for Tucumcari, the alternate airport, indicated clear weather until 0500, followed by an overcast, with a ceiling of 800 feet and surface winds from the northeast at 15 miles per hour. The flight was routine and on reaching Acomita, New Mexico, at 0755, reported that it was 500 on top at 12,000 feet and was estimating Albuquerque at 0811. Following this report the flight asked to change its flight plan to Tucumcari with Amarillo, Texas, the alternate, and requested the latest Tucumcari weather which was: 0728, overcast, 1500 feet, visibility 20 miles, wind northeast 20 mph; Amarillo, 0728, broken clouds 1700 feet, overcast at 3500 feet, visibility 8 miles, wind north-northeast, 17 mph. The flight passed over Albuquerque under broken clouds in the clear at 12,000 feet NSL at 0813, whereupon the following clearance was given: “ARTC (Air Route Traffic Control) Clears CAM 5763 to the Tucumcari Airport via Green Airway No. 4, to maintain 500 on top while in the control area.” This clearance was acknowledged. At 0831, the flight reported being over Anton Chico, New Mexico, at 13,000 feet, estimating Tucumcari at 0852. At this time the 0828 Tucumcari weather was given the flight as; coiling estimated 1,000 feet, overcast, visibility 3 miles, snow and fog. At approximately 0845, Tucumcari radio gave 5763 the following clearance: “ARTC clears 5763 to descend to 8,000 feet on the south course of Tucumcari range, maintain 11,000 feet until 2 minutes south, descend outbound, maintain 8,000, report leaving 9,000.” The following clearance was transmitted to the flight by Tucumcari radio at 0851: “ARTC clears 5763 to approach Tucumcari Airport en reaching 8,000 feet.” The flight next reported being over the Tucumcari range station at 0852, at 11,000 feet, descending to 8,000 feet, and at 0901 reported that it was at 9,000 feet outbound on the south leg of the Tucumcari range. At this time the special 0852 Tucumcari weather report was given the flight: “Ceiling 800 feet, overcast, visibility one mile, light snow and fog, wind north 20 miles per hour with strong gusts.” The reported surface visibility in this official weather report was loss than the CAA and company minimums of 11/2 miles for the Tucumcari Airport. At 0907 5763 was given the following clearance: “ARTC clears 5763 to make standard instrument approach.” The Amarillo weather was then given as: coiling estimated 1,000 feet, broken clouds, overcast 2,000 feet; visibility 5 miles, light snow and fog. The flight was asked if it wished to proceed to Amarillo and it replied that it had to land at Tucumcari. The flight continued its descent and at 0909 was advised by Tucumcari radio that the Tucumcari weather was then ceiling 800 feet, overcast, visibility 1/2 miles, light snow and fog, wind north 20 miles per hour. Two minutes later, at 0911, the flight reported it was outbound on the west leg at 8,000 feet, descending to 6,000 feet. Tucumcari radio again gave the flight the weather which had been given it at 0908. One minute after this transmission Tucumcari radio gave the flight the wind direction which was then north-northwest, variable to north-northeast, at 16 miles per hour, and advised that Runway 30 was the runway in use. 5763 immediately requested the bearing of this runway and this was corrected to 03, which was acknowledged by the flight. At 0915 5763 reported that it was at 6,000 feet and inbound on the west leg of the Tucumcari range. Immediately following this report, at 0916, Tucumcari radio asked the flight if it wanted ARTC to recommend an alternate airport closer than Amarillo. The flight acknowledged this and advised it would have to land at Tucumcari but asked where the alternate would be. The pilot was advised to stand by and, according to the communicator on duty, the aircraft was then seen to cross the field in a northwesterly direction at very low altitude. The pilot was quickly advised to pull up and answered that he was doing so. At 0925, the flight advised it was landing downwind. This was the last report received from the flight. After several passes over the airport at altitudes varying from 500 feet to as low as 50 feet, the aircraft crashed near the northeast end of Runway 21 at approximately 0929. A flash fire which occurred immediately after impact quickly subsided. Ten passengers were injured and another one was killed. The aircraft was destroyed.

On final approach to Kirtland AFB, the crew encountered strong crosswinds up to 35 knots. After passing over the runway 08 threshold, while at a height of 200 feet, the aircraft banked right, causing the engine number six to hit the runway surface. On impact, the engine was seriously damaged and caught fire. The pilot in command attempted to make a go around when the aircraft nosed down and crashed in a huge explosion. Two passengers were seriously injured while 23 other occupants were killed.

Three minutes after takeoff from runway 08 at Kirtland AFB, while in initial climb, the heavy bomber went out of control and crashed in a huge explosion on a mountain slope located near Sandia, about 5,7 miles east of the airbase. The aircraft was totally destroyed and all 13 crew members were killed. Detonators were installed in the bomb on board the aircraft. The bomb case was demolished ans some high explosive (HE) material burned in the gasoline fire. Other pieces of unburned HE were scattered throughout the wreckage. Four spare detonators in their carrying case were recovered undamaged. There were no contamination or recovery problems. The recovered components of the weapon were returned to the Atomic Energy Commission. Both the weapon and the capsule of nuclear material were on board the aircraft but the capsule was not inserted for safety reasons.
