The disappearance of Malaysia Airlines Flight 370 in March 2014 has baffled investigators. A Boeing 777 jet with 239 people on board simply vanishing in midflight is something that modern technology is supposed to prevent.
But disappearances like Flight 370 are more common throughout history than many people realize. Here are five vanishings that remain unsolved.
1948 DC-3 flight
A DC-3 airliner disappeared between San Juan and Miami in December 1948.
On December 28, 1948, a 64-foot-long DC-3 airplane took off from San Juan and headed toward Miami, carrying 29 passengers and three crew members, according to the New York Times.
Despite clear weather and high visibility, the plane never made it to Florida.
No probable cause for the loss was determined by the official investigation.
