SPONSORED VIDEO Currently, passenger planes are visually very similar to each other, especially when we are talking about modern planes with turbofan engines. Here, it does not matter whether the manufacturer has been operating for decades or is, for example, a new Chinese creation, if we are not fascinated by aviation and do not know the individual manufacturers, it will be difficult for us to notice the differences. The optimal design, which manufacturers still use today, was created very quickly, because it was created right after 1945 thanks to Dehavilland Comet, the famous comet was the first passenger jet plane, for which it paid a high price, but their design was later copied by manufacturers. However, manufacturers, for some reasons, tinkered with the engine layout and at some point it became very popular to mount engines in the tail section! But why? Why did the manufacturers return to the idea of Dehavilland's designers and to this day, even though more than 70 years have passed, they are still similar to the Comet?
