The Bristol Aeroplane Company had a proud and long tradition of building fine aircraft, from the Bristol Boxkite of 1910, the Bristol Fighter of WW1, and the Blenheim and Beaufighter of WW2. It is surprising then that the company only built one jet aircraft, the exotic Bristol 188 high speed research aircraft. The Bristol 188 was intended to examine the effects of sustained kinetic heating on stainless steel aircraft structures over long periods. To this end the Bristol 188 featured a refrigerated cockpit, and advanced telemetry so that the aircraft could be monitored by a second pilot on the ground.
