In addition to airplanes, air transportation which is also widely used is helicopters. In contrast to large planes, helicopters are much smaller in size with different shapes.
Because of their different sizes, the number of passengers that can be carried by helicopters is of course also less compared to planes that can carry up to hundreds of passengers.
Try observing the shape of the helicopter, do you realize that the helicopter has a shape similar to an insect?
The shape of the helicopter was inspired by the dragonfly insect. Not only flying horizontally, the helicopter can also fly perpendicularly or vertically, both up and down. Besides being able to fly forward, the helicopter can also fly backwards and sideways.
Another flying ability possessed by helicopters and inspired by dragonflies is that they can float in the air without moving.
