Because all they need is their main rudder to spin fast enough to get the helicopter off the ground. They need only enough room to spin the rudder and for the helicopter to fit in a space. They don't need to go forward fast to lift off, unlike planes and shuttles.
Take On Helicopters happened in 2011.
No. Helicopters need air to fly. There is no air on the surface of the moon. Therefore helicopters could not fly on the moon.
Take On Helicopters was created on 2011-10-27.
They have no need of runway because they can lift off vertically
Helicopters has a limited range compared to planes. Planes need a long pave to operate while helicopters can take off and land a lot more places. Also helicopters can "stand still" in the air while planes need to move all the time. So depending on what you want to do they have different (dis)advantages.
They don't need an airstrip. They can take off and land anywhere (weather and ground fire permitting).
Vertical take off and set down for one Helicopters can hover.
Helicopters take off and land from a heliport, consisting of a landing pad (usually has an H on it) and a satellite.
A place, area or platform within a wider area specifically designated for helicopters is a helipad; a specially created terminal and ground zone for helicopters is called a heliport. Otherwise, helicopters can generally land whenever and wherever they need to, as long as there is enough space for the rotors to fit and enough fuel for them to get out again.
A helipad
heliport
Helicopters can take off from anywhere - runways, docks, building roofs, ship's decks. If it's a purpose-made spot it's usually called a helipad or a heliport.
