A regional jet (RJ) is a jet-powered regional airliner with fewer than 100 seats. The first one was the Sud-Aviation Caravelle in 1959, followed by the widespread Yakovlev Yak-40, Fokker F-28, and BAe 146. The 1990s saw the emergence of the most widespread Canadair Regional Jet and its Embraer Regional Jet counterpart, then the larger Embraer E-Jet and multiple competing projects. In the US, they are limited in size by scope clauses.
