Built 1965 as model 400, later modified to 500, 475 and 670 prototypes. Seen here as model 475AM with hush kits. Retained by BAC/BAe for all its life as prototype, flight test, research and corporate shuttle aircraft. Retired 12 October 1993, flown to Brooklands Museum 14 June 1994 for preservation.

slide scan from my collection. - G-ASYD, a common visitor to Munich-Riem airport, flew a few sorties in white, before it was repainted in its final blue/red/orange stripe-colours. These should become the colours, in which the aircraft has been displayed at the Brooklands Museum since June 1994; seen there again in April 2023 - a beautiful restoration.

slide scan from the NK collection. - G-ASYD was a common visitor to Munich-Riem, and it is pictured here in a medium colour-scheme; the titles "BRITISH AEROSPACE" had been applied to the aircraft about two years earlier.

slide scan from the NK collection. - G-ASYD was a common visitor to Munich-Riem airport. The aircraft is shown in a medium colour-scheme, but still without the titles "British Aerospace", which should be applied to the aircraft about two years later.

Development aircraft for British Aircraft Corporation, carrying out testflights for BEA. Later preserved at Brooklands.

K25 slide scan. Built 1965 as model 400, later modified to 500, 475 and 670 prototypes. Retained by BAC/BAe for all its life as prototype, flight test, research and corporate shuttle aircraft. Retired 12 October 1993, flown to Brooklands Museum 14 June 1994. Shown here at its first display spot at the museum.

Originally the Srs. 400 development aircraft first flown on 13 July 1965, converted as the Srs. 500 prototype which flew on 30 June 1967, and then the Srs. 475 prototype which flew on 27 August 1970. In 1977 G-ASYD was converted yet again as the Srs. 670, developed with the Japanese market in mind. In this form it first flew on 13 September 1977, and made an appearance at Farnborough in 1978, however this version was not proceeded with. It has since been preserved at Brooklands Museum, Weybridge, flying there from Hurn on 14 July 1994.

Retired 12 October 1993, flown to Brooklands Museum 14 June 1994. Flew a Warton Munich company shuttle and occasionally diverted to Nuremberg during the winter months. Has a replacement primer door fitted.

BAC development aircraft

Former British Aerospace testbed

Former British Aerospace Fly-By-Light development aircraft, with matching "Fly By Light Control Technology" titles. Was flown from Filton to the museum on delivery on 14 July 1994.

The BAC One-Eleven 475 was the 'hot and high' version of this bus-stop jet, combining the -500s more powerful Spey engines with the lighter -400 airframe, and at cold wet Farnborough it gave a lively show....Noisy, though!

This One-Eleven was retained by the BAC/BAe throughout its 29-year flying career for use as a development and test aircraft for the production variants and for testing technical innovations. One such deveopment is alluded to by the 'Fly-By-Light Flight Control Technology' titles where it was thought that if the flight control inputs were driven by light rather than electrical inputs, then these would be much harder for any putative enemy to jam.
