The British Aerospace ATP (Advanced Turboprop) was designed to supersede the popular Hawker Siddeley 748, but entered an increasingly crowded market and failed to emulate its predecessor’s success. Stephen Skinner tells the ATP’s story.

Hawker Siddeley’s first 748 flew from Woodford, near Manchester, on June 24, 1960 and, owing to a programme of constant improvement, sold well with orders only beginning to trail off in the mid-1980s when the ATP was ready to take to the air. In total 381 748s were constructed at Woodford and in India.
