Gloucester has a long history in the aerospace business. In 1926 the Gloucestershire Aircraft Company at Brockworth changed its name to the Gloster Aircraft Company because international customers claimed that the name "Gloucestershire" was too difficult to spell. A sculpture in the city centre celebrates Gloucester's aviation history and its involvement in the jet engine. Frank Whittle's pioneering turbojet engine powered the Gloster E.28/39, the first British jet aircraft, which first flew at the company's airfield at Brockworth. This is commemorated by the pub "The Whittle" at Gloucester Business Park, which now occupies the site. Roads in the business park are named after other Gloster aircraft and a small statue overlooks the site of the old main runway. Messier-Dowty's landing gear plant and GE Aviation Dowty Propellers plants are on the outskirts of the city.
