Many ships and planes had disappeared without any following in recent decades, a vast triangular area of the Atlantic Ocean, with imaginary points in Bermuda, Florida and Puerto Rico.
But the survey by the BBC journalist Tom Mangold offers plausible explanations for the "evaporation" of two British commercial aircraft in that area, with all of the 51 passengers and crew on board. One aircraft suffered a technical failure disastrous likely caused by a design error and the other seems to have ran out of fuel after the pilot decided to fly at a height of only 600 meters altitude at which consumption is big. After 60 years, commercial flights London-Bermuda were only the beginning and had a highly dangerous.
What was needed was a stop for refueling in the Azores, before flying over 3200 miles to Bermuda, which was then the longest commercial flight overseas without interruption, in the world. So often, the fuel reached the limit. Today, planes landing at the tiny Atlantic island have sufficient fuel reserves to reach, in case of emergency, on the East Coast of the United States, situated at over 1,100 of miles away. Moreover, the planes before the period of the Second World War were not very reliable. British South American Airways, the company that have flights from London - Bermuda, had, in just 3 years, 11 serious injuries and lost five planes, which had on board 73 passengers and 22 crew members.
