An airplane (North American English) or aeroplane (British English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones.
Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, which are used for transport, cruise ships typically embark on round-trip voyages to various ports of call, where passengers may go on tours known as "shore excursions".
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway.
A more recent term for high-performance sportscars is "hypercar", which is sometimes used to describe the highest performing supercars. An extension of "supercar", it too lacks a set definition. One offered by an automotive industry writer is "a limited-production, top-of-the-line supercar"; prices can reach or exceed US$1 million, and already had by 2017.
A supercar, also known as an exotic car, is a type of automobile generally described at its most basic as a street-legal sports car with race track-like power, speed, and handling, plus a certain subjective cachet linked to pedigree, exclusivity, or both. The term 'supercar' is frequently used for the extreme fringe of powerful, low-bodied mid-engineed luxury sportscars. A low car has both a low, handling-favorable center of gravity, and less frontal area than a front engined car, reducing its aerodynamic drag and enabling a higher top speed. Since the 2000s, the term hypercar has come into use for the highest performance supercars.
A superyacht or megayacht is a large and luxurious pleasure vessel. There are no official or agreed upon definitions for such yachts, but these terms are regularly used to describe professionally crewed motor or sailing yachts, ranging from 40 metres (130 ft) to more than 180 metres (590 ft) in length, and sometimes include yachts as small as 24 metres (79 ft).
