Helicopters with no people - level 2, A12
When you see a helicopter, you think that there is a pilot in the helicopter who flies it. Usually, it is still true, but there is a new boom in producing planes and helicopters with no pilots. These machines are used for different reasons, usually in the army and in agriculture.
The boom is 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.
