Jack Northrop dreamt of aircraft where everything not absolutely essential for flight was eliminated. Leonardo da Vinci’s theoretical flying machines from the 15th century, Sir George Cayley’s Governable Parachute of 1852, the Wright Brothers’ Flyer of 1903 and virtually ever other flying machine all have one thing in common: they all have tails of one sort of another which are used to stabilize and control their flight.

On February 19th, 1959, Władysław ‘Spud’ Potocki was test flying the sparkling white Avro Arrow RL-201 in the fair but chilly skies near Malton, Ontario. On that particular flight, the World War II veteran fighter pilot was testing the Arrow’s roll rates at Mach 1.7. While fast, it was still well below the nearly twice the speed of sound the sharp, delta-wing aircraft had already achieved on previous test flights. As aeronautical engineers like to say, the Arrow had ‘flown off the drawing board’. The celestial expectations for the all-new, Canadian-designed and built supersonic interceptor were being met or exceeded with each passing day …
