AVISTAMIENTO DE FENOMENOS EXTRAÑOS (EXPEDIENTE NÚMERO: 790313)

This document is an official report from the Spanish Air Force (Ejército del Aire) regarding an unidentified aerial phenomenon (UAP) incident that occurred on March 13, 1979. The report, filed under number 790313, details the detection of an unknown radar trace by the Surveillance Section of the Pegaso Sector Operations Center (SOC). At 09:59Z, the object was detected moving at 840 knots on a 280-degree heading. An interceptor aircraft was scrambled from the Manises Air Base (LEAB) at 10:02Z to identify the target, but the trace disappeared from the screen before interception could occur. Shortly thereafter, a new stationary trace was detected, initially suspected to be a ship. As the interceptor approached within 8 nautical miles, the object began moving at 730 knots at an altitude exceeding 80,000 feet. It eventually changed its heading to 080 degrees and disappeared permanently. The document includes a summary of the events, a reference to a March 29, 1979, report from the MACOM Chief to the EMA Chief, and a declassification notice dated February 13, 1995, stating that the incident no longer required classified status.
