Passage: The Martin Jetpack is a small VTOL device with two ducted fans that provide lift and a 2.0-litre V4 piston 200-horsepower gasoline engine. Although its pilot straps onto it and does not sit, the device cannot be classed as a backpack device because it is too large to be worn while walking.  However, the Martin Jetpack does not meet the Federal Aviation Administration's classification of an ultralight aircraft: it meets weight and fuel restrictions, but it cannot meet the power-off stall speed requirement. The intention is to create a specific classification for the jetpack –  it uses the same petrol used in cars, is relatively easy to fly, and is cheaper to maintain and operate than other ultralight aircraft. Most helicopters require a tail rotor to counteract the rotor torque, which, along with the articulated head complicate flying, construction, and maintenance enormously. The Martin Jetpack is designed to be torque neutral –  it has no tail rotor, no collective, no articulating or foot pedals –  and this design simplifies flying dramatically. Pitch, roll and yaw are controlled by one hand, height by the other.
