News 4 This Morning is taking a look at some of the most unusual aircraft from the past century.
The appropriately named VertiJet, also known as the X-13, was designed to help prove that jets could take off vertically and land the same, without the need for a long runway. That landing was especially tricky, since a pilot had land on a special trailer, without being able to see behind them. A specially marked wire that stuck up from the trailer helped with this process. The flight tests of the VertiJet were successful, but without a specific purpose, the project didn't go any further. The only built are on display at two different US museums.
When you think of biplanes, you most likely think of the early days of flight: the Wright Brothers...the Red Baron and the like. But in the 1970s Poland made the world's only jet bi-plane! The Belphegor translates into "the noisy demon." Although a plan for over 3000 of these agricultural crop-dusters to be made was put into action. The unusual aircraft only had about 175 made. The “Noisy Demon” was only used in the Soviet Union and its speed of 94 miles per hour makes it one of--if not the--slowest jet aircraft to be made.
