Harrier Jump Jet II Plus configuration) was delivered in December 2003, ending the Harrier production line. The Harrier Jump Jet, capable of taking off vertically, can only do so at less than its maximum loaded weight. In most cases, a short take off is performed, using forward speed to achieve aerodynamic lift, which uses fuel more economically than a vertical take off. On aircraft carriers, a ski-jump ramp is employed at the bow of the carrier to assist the aircraft in becoming airborne. Landings are typically performed very differently. Although a conventional landing is possible, the range of speeds at which this can
Musk electric jet Musk electric jet The Musk electric jet is a jet-powered supersonic electric aircraft concept by entrepreneur Elon Musk. Specific design concepts for a vertical-takeoff-and-landing supersonic electric jet were first made public by Musk in 2014. The concept includes a large percentage of the aircraft by weight being made up of high-capacity batteries and significantly decreasing the amount of aircraft structure devoted to control surfaces, depending to a greater extent on "gimbaling the electric fan" for control of aircraft attitude. Musk had publicly mentioned the supersonic electric jet idea as early as 2012. Initial public discussion of the design concepts behind
