Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines and aircraft achieve maximum efficiency (see specific impulse) at speeds close to or even well above the speed of sound. Jet aircraft generally cruise at faster than about M 0.8 (609mph, 981km/h or 273m/s) at altitudes around 10,000–15,000 metres (33,000–49,000ft) or more.
Frank Whittle, an English inventor and RAF officer, developed the concept of the jet engine in 1928,Hans von Ohain in Germany, a decade later developed the concept independently at the end of the 1930s. He wrote in February 1936 to Ernst Heinkel, telling him of the design and its possibilities. However, it can be argued that the English engineer A. A. Griffith, who published a paper in July 1926 on compressors and turbines, also deserves credit.
The aircraft are said to be capable of sustained flight at Mach 2, equivalent to over 1,400 miles per hour, while holding up to 88 passengers. The company estimates that the supersonic jets could cut commercial-flight times between New York and London from the current six and a half hours to just three and a half.
Investigators believe the jet, which was operated by a military contractor, was part of a two-plane formation finishing weapons school support flights. Moments before the May 24 crash, Hamilton reported the jet had no problems.
LAS VEGAS (AP) — A civilian pilot killed when a Dassault Mirage F-1 crashed last month near Nellis Air Force Base reported a flight emergency and ejected moments before the jet slammed to the ground and burst into flames, federal crash investigators reported Friday.

Passengers on a flight from Los Angeles to Atlanta were terrorized when a man tried to open one of the doors on the jet. According to The Independent, witnesses said the crew asked for “strong men” to assist in subduing the passenger on the Delta flight.
