Helicopters with no people - level 3, A12
When you see a helicopter, you expect to see a pilot sitting in the cockpit and flying the helicopter. In most cases it is still true, but there is a new boom in producing unmanned planes and helicopters. These machines are used for different purposes, mainly for the army and agriculture.
The boom is especially big in the US and China. One Chinese company is selling three times more of these machines than 2 years ago. They have a big plan to produce more and sell in other countries too.
