How it's Made: Helicopter

Compared to other vertical lift aircraft like tiltrotors (V-22 Osprey for example) and vectored thrust airplanes (also known as VT-OL jets, standing for Vertical Take-Off & Landing) (AV-8 Harrier for example), helicopters are very efficient, carrying more than twice the payload, consuming less fuel in hover and costing considerably less to buy and operate[via Wikipedia]
