An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

 powered aircraft like the Fokker F-27.

These earlier large 50 passenger aircraft had begun to trickle down to the larger trunk and minor airlines, which were used on shorter range regional routes that had become their forte, especially in the U.S. Smaller "mini-airliners" soon found niches regionally in the 1960s when aircraft manufacturers such as the British made Shorts Skyvan, Brazilian Embraer EMB 114 Bandirante, and French Nord 262, all sought to capture the lower end of the DC-3 replacement market.

In the 1970s, the market for smaller sized mini-airliners boomed with the process of route liberalization

 cities. The same market forces also allowed these "mini airliners" to be rapidly supplanted by faster longer range, first generation turbofan powered regional jets (as the first generation Bombardier CRJ became known), differentiating them from prior generation equipment.

Another reason for the downturn in the turboprop market was the introduction of the first regional jets. Although a number of small jets entered service in the 1950s and 60s, notably the Sud Aviation Caravelle

 and Yak-40, these could not compete in terms of cost of operation with the turboprop designs, and were suitable for routes with small numbers of passengers, as opposed to short routes where fuel economy was paramount. As engine technology improved, this difference continued to narrow, until the higher utilization factors due to higher cruising speeds erased any remaining advantage from lower operating costs.

The earliest example of a true short-range jet is the BAe 146

 before it, the BAe 146 was tuned to a very specific market, city-center to city-center service where low noise and excellent takeoff performance were paramount. Like the Dash 7, the market niche for this design proved to be fairly small, and its four engines meant it had higher maintenance costs than twin-engine designs. Unlike the Dash 7 example BAe did not respond by producing a twin-engine design that filled the same range requirements but offering lower operational costs.

This was addressed by Bombardier's twin-engine Canadair Regional Jet, which became a best-seller. The CRJ's range is enough to fill mid-range routes as well, routes previously served by larger aircraft such as the Boeing 737

. Although not as economical as the turboprop, by flying directly to and from smaller airports, they reduced the need for low-cost regional airliners. And although turboprops are quiet to outside observers, propwash makes them very noisy inside. Passengers greatly preferred jets, both for real and perception reasons.

As had happened with the turboprops of only a few years earlier, the success of the CRJ led to the introduction of a host of competitors. The only successful example is the Embraer ERJ 145, which has seen excellent sales and has competed strongly with the CRJ in most markets. Bombardier and Embraer have been locked in a series of counter-lawsuits over export taxes and subsidies ever since. The ERJ's success led to a totally new version, the Embraer E-Jets

 to compete, but went bankrupt soon afterwards and the type did not enter large scale production. Their bankruptcy also ended development of the more competitive Fairchild-Dornier 728, which had attracted strong airline interest. The CRJ/ERJ also resulted in the end of the BAe 146 line.
