A New Risk
The Arrow was a sleek, risk-taking, and well-designed aircraft. It stretched the limits of flight as we then understood it. But it happened to be there at the wrong time. The USSR managed to alter the priorities of the West with a single action. Political shift signalled the Arrow's doom. New treaties with the US were negotiated and ratified as the government changed hands. Most importantly, the appearance of Sputnik signalled a threat coming from a level higher than before.
