Aviation has opened new opportunities for both individual achievement and public service during the past 80 years. The author discusses his experiences during the second half of the modern era of powered flight, including combat activities during World War II, work as a test pilot developing flying techniques for the first jets, challenging the world altitude record, and assessing the performance capacities of different aircraft. The lecture devotes special attention to aerobatic flying, especially the properties of the spin. The author relates these personal experiences to the responsibilities of guiding modern aviation to improved public service in the coming years.
