Tehran F-4 Radar-Visual Intercept and System-Failure Report

September 19, 1976Tehran airspace, Tehran, Iran

Hall summarizes the Tehran incident in which two successive Iranian F-4 interceptors attempted to approach a radar-visual target and reportedly experienced weapons/electronic system failures when preparing to engage it. He notes a U.S. DIA report regarded the case as outstanding.
