It's more than just the Hawker name and it's more than 93 years. What became the line of Hawker business jets began life as the de Havilland DH-125. Although Hawker Siddley had purchased DH before development began, the design and construction was undertaken by de Havilland. It did not become the HS-125 until after more than 80 aircraft were built and in service. Thus it was the final design (not counting de Havilland Canada and Australia) to come out of a company whose history goes back to Airco, which operated from 1912 to 1920 and for whom Geoffery de Havilland was chief designer. The (hopefully temporary) death of the Hawker line brings to an end a design lineage over 100 years old which began a mere 9 years after powered flight itself. I cannot think of a single aircraft line with a longer history.
