This new edition of "Flying Concorde" has an added section that covers the cause of the Paris tragedy and the remedies and improvements that have been made in the light of the accident report. It also brings the reader up to date with many other improvements that have been made to the aeroplane that will keep it in service for many years to come. During Concorde's entry into service with British Airways, Brian Calvert was flight manager (technical) and responsible for deciding the methods by which Concorde would be flown, the flying qualities of the aircraft and its suitability for potential routes. He carried out acceptance trials and flew several of its inaugural flights.
