#1- Nazi Jetcopter
During the early times, it seemed that helicopters would just remain an idea, or a doodle on the paper. History is witness to the fact that there have been people like Leonardo Da Vinci who had a very clear idea about how the helicopter would look. Everything was on paper, but there was one issue and that was how you would control the whole thing. During the very first attempts, one of the problems that was faced was that helicopter would only spin along the blades. The Germans were finally successful in making a helicopter that actually flew from one point to the other with the help of propellers.
#2- Russian Tsar Tank
The second thing on this list is the Russian Tsar Tank that looked one of those cycles that that were used in circus in the 1800s. The only difference being that the tanks here actually had armor and guns. The tsar tank was as dangerous as it seemed but the issue was that the length of the lead pipe was proving to be fatal for the people. This is one of the primary reasons why the design did not get a heads up after the testing stage. The design paid attention to the wheels but did not pay heed to the things to whatever was going on at the back. It was seen that whenever the vehicle moved over mud, the wheels sank and were very hard to pull out.
#3- Corkscrew Tank
The corkscrew tank looked straight out of a horror movie. The vehicle travelled sideways and trotted upon different types of terrain. One strange issue was that the vehicle did not work well on smooth terrains, which means that it was of no use to the army. Another problem was that the tank was extremely slow and steering was not easy because the screws could not move from side to side and there were no suspensions whatsoever.
#4- GE Quadruped
The GE quadruped, or the walking truck, was another vehicle that was unique in its own right, driven with the operator’s own limbs. The vehicle never went pass the designing stage because it was costly to take the plan forward and it wasn’t even easy to operate the GE Quadruped. Another issue was that that the quadruped was extremely noisy and could be heard from a distance, which is the sort of heads up that you don’t want to give your enemies when you are at war. Sure technology would have made things better, but the question remains that how would you use the GE quadruped.
The cannon shooter basically combined a scooter with a cannon (hence the name). The main idea behind the whole concept was to fire as you go. Imagine a scooter with a gun or simply have a look at the provided picture. It’s hard to steer with a person in the back, imagine how hard it must have been to move with an artillery canon that you are actually sitting on top of.
