28 December 1948, Douglas DSTairliner

On the evening of December 28, 1948, a Douglas DSTairliner, registered NC16002, vanished just before the scheduled departure from San Juan, Puerto Rico, to Miami, Florida. Three crew members and 29 passengers were on board the aircraft. The official investigation found no probable cause for the loss, so it is still unsolved.

A potential clue to the plane’s disappearance was discovered from the paperwork gathered by the Civil Aeronautics Board investigation, although it was hardly mentioned by the Triangle writers: the plane’s batteries were examined and found to be low on charge, but the pilot ordered them back into the aircraft while it was in San Juan. It will never be known if this resulted in a total electrical failure. This theory is not very compelling, though, because piston-engined aircraft use magnetos rather than battery-powered ignition coil systems to supply spark to their cylinders.

The B-47E serial number 52-534 failed to make contact with its tanker at 14,000 feet (4,300 metres) after descending through solid cloud to start the second refuelling.A nuclear detonation was not possible because the unarmed aircraft was transporting two capsules containing material for nuclear weapons in carrying cases. The crash site has never been located, and no debris has ever been discovered despite a thorough search.

21 October 1978.training flight in a Cessna 182L

On Saturday, October 21, 1978, Frederick Valentich, then twenty years old, vanished during a 125-mile (235-kilometer) training flight in a Cessna 182L light aircraft over Bass Strait in Australia.

Known as a “flying saucer enthusiast,” Valentich reported via radio to Melbourne air traffic control that an aircraft was following him at a height of approximately 1,000 feet (300 metres) and that his engine had started to run erratically. Ultimately, he concluded by saying, “It’s not an aircraft.”

The Department of Transport was sceptical that a UFO was the reason behind Valentich’s disappearance, according to the Associated Press, which also noted that some of their officials surmised that “Valentich got disoriented and saw his own lights reflected in the water, or lights from a nearby island, while flying upside down.” These reports of a UFO sighting on the night of the disappearance were made belatedly in Australia.

March 2014,  Malaysia Airlines Flight 370

On March 8, 2014, Malaysia Airlines Flight 370 (MH370/MAS370)[b], a scheduled international passenger flight, vanished while it was travelling from Kuala Lumpur International Airport in Malaysia to Beijing Capital International Airport in China. The aircraft was over the South China Sea less than an hour after takeoff when it last made voice contact with air traffic control on March 8 at 01:19 MYT (17:19 UTC, March 7).

It vanished from the radar screens of the air traffic controllers at 01:22 MYT. As the plane veered off course and crossed the Malay Peninsula to the west, Malaysian military radar kept track of it. At 02:22, while over the Andaman Sea, 200 nautical miles (370 km) north-west of Penang in northwest Malaysia, it departed the range of Malaysian military radar. The Boeing 777-200ER aircraft was carrying 227 passengers from 15 different countries along with 12 Malaysian crew members.

After the aircraft’s signal was last picked up by secondary surveillance radar in the South China Sea and the Gulf of Thailand, a global search and rescue operation quickly expanded to include the Andaman Sea and the Strait of Malacca. The flight continued until at least 08:19 and flew south into the southern Indian Ocean, according to an analysis of satellite communications between the aircraft and Inmarsat’s satellite communications network, though the exact location is unknown.

On March 17, Australia assumed command of the search and shifted it to the southern Indian Ocean. The Malaysian government declared on March 24 that “Flight MH370 ended in the southern Indian Ocean,” citing the fact that the final location ascertained by the satellite communication is remote from any potential landing sites.The majority of the aircraft has not yet been found, despite the discovery of numerous more tiny pieces of debris, which has led to the creation of numerous theories regarding its disappearance.
