Aeronaves de México Flight 111

Aeroméxico Flight 111 was a scheduled commercial flight from Tijuana to Acapulco with stopovers in Mazatlán, Guadalajara, and Mexico City. On June 2, 1958, the Lockheed L-749 Constellation was operating a scheduled flight and crashed near Tlajomulco de Zuñiga, killing all 45 occupants.

Accident

The aircraft Lockheed Constellation was a four-engine (four-propeller) aircraft, registered as XA-MEV, originally built in 1951 and delivered to Air India as VT-DEO. It was sold to Lockheed Aircraft Corporation in early 1958 to be handed to a new owner. The ill-fated aircraft was owned by Aeronaves de México (now Aeroméxico) and incorporated into service in February 1958. The pilots were both experienced; the flight was headed by Captain Alfonso Ceceña Gastélum, who had around 15,000 flight hours, and First Officer Roberto Herrera had 10,000 flight hours logged. The aeroplane landed at Guadalajara around 20:00 CST and took off from Runway 28 at 21:53 CST, after completing the leg from Mazatlán to Guadalajara's old airport (which at the time was located 16km from the now-actual Miguel Hidalgo y Costilla International Airport).

The expected one-hour flight plan included to follow a strict instrument-based references after taking off which had to be carried out during climbing towards México City, the flight path included to do a tear drop left turn with while holding after taking off -due to the airport location at the time- the plane expected to climb and keep a left turn, but due to the current weather and time, the plane stopped the turn. The plane halted its turn and was set to a straight direction for another two minutes -unknown at the time- the plane was flying low and was headed into an out-of-course path.

The plane tried to correct the flight path process without visual references outside, the plane kept flying straight in a south-westerly direction, at 20:00 CST the flight was unknowingly headed straight towards Cerro Latillas. Contact with ATC was severed after no update was received. Another flight -Mexicana de Aviación, Douglas DC-3- was advised to maintain a holding pattern while flying around the Guadalajara metro-area due to weather complications and had to wait for landing clearance from the tower after the Constellation's takeoff. The DC-3 asked through radio to the ill-fated plane for their position and whereabouts after seeing a fireball coming from the ground. ATC asked the DC-3 to maintain their hold due to the weather getting worse. Mexicana pilots notified ATC about their holding pattern and received no answer from Flight 111 despite several attempts. Authorities and emergency services were deployed after no contact was made with ATC. Aeronaves Mexico City's terminal called Guadalajara around 2 AM stating [the] plane had been delayed several hours with no whereabouts.

The constellation wreckage was found by authorities the following morning after the crash. The crash site was charred and found around the outskirts of Tlajomulco de Zúñiga. Local villagers tried to contact authorities minutes after a plane was heard flying close to the ground and crashing afterwards with no success. The aircraft carried 38 passengers and seven crew members, all of whom perished instantly.
