AI-Generated Summary

This installment of Check 6 Revisits looks back fifty years to the 1976 defection of a Soviet pilot who flew a MiG-25 to Japan, and traces how Aviation Week covered the story. 

The episode begins at the 1967 Moscow Air Show, where the aircraft debuts before a crowd of spectators while Western attachés and journalists watch from a standing area. Its enormous inlets and wings lead observers to conclude that it is a Mach 2.5 to 3 interceptor and possibly an agile, lightweight air superiority fighter built with titanium. The conversation places that assumption in context, covering the Western supersonic programs of the era, the cancelled high-speed, high-altitude projects, and the sharp break the design represents from earlier Soviet fighters. It also describes how the revelation pushes the American F-X requirements away from a heavy, multirole concept toward a pure air-to-air fighter, which becomes the F-15.

The narrative then follows the September 1976 flight in detail: the pilot's motives, a low-level run toward the coast, a diversion to a civilian airport, a landing with almost no fuel and a stunned crowd. Analysts disassemble the aircraft over about two months and find mostly steel rather than titanium, a powerful vacuum tube radar, limited agility and engine limits at top speed. 

The episode closes on the lasting consequences for both sides, including Soviet radar and missile upgrades, the Flanker and MiG-31 programs, a radar compromised by a spy and prompt reporting from Pentagon briefings, with the full magazine archive available online.
