Tehran 1976 — Imperial Iranian Air Force F-4 Intercept
Two Imperial Iranian Air Force F-4 Phantom jets scrambled to intercept a bright object over Tehran. Both aircraft experienced complete weapons system and communication failures when attempting to engage. The object released a smaller object that pursued one of the F-4s. A DIA (Defense Intelligence Agency) report classified the case as an 'outstanding UAP report' and it became one of the most cited US intelligence UAP documents, later released via FOIA.
