<human>:  What is the difference between an aeroplane and a helicopter?
<bot>: The main difference between an aeroplane and a helicopter is that aeroplanes are heavier and rely on wings for lift, while helicopters use spinning rotors for lift. Helicopters are also more agile than aeroplanes, allowing them to take off and land vertically, travel in any direction, and hover in the air. Aeroplanes are usually faster, but helicopters are limited to short distances.
