Perhaps most important for many business professionals, however, are the freedom and security that only private jets can offer. A private jet is a productivity multiplier, allowing you and your company to be more competitive, nimbler, and more successful, by optimizing your time, flexibility, and efficiency. In today's ever-competitive global marketplace, a private jet enables direct, face-to-face contact with clients, customers, and personnel, to a degree not otherwise possible.
Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
