On May 9, 1980, at the Mariano Melgar air base in Peru, radar picked up a UFO at the end of the runway and at a height of 1,800 feet. One of the air base's fighter pilots took off to intercept the object, engaging in an aerial game of chicken with the unknown object for over 18 minutes until lack of fuel caused him to return to the base. The team examines a declassified US Department of Defense report which analyzed this encounter, and interviews the pilot to get his complete story. And, on September 19, 1976, a UFO was seen by witnesses and picked up on radar above the skies of Teheran, Iran. The Iranian Air Force scrambled two F-4 Phantom jets. General Parviz Jafari, squadron leader and one of the F-4 pilots involved in the incident, explains how he pursued the object, got a radar lock and as he prepared to fire his AIM 9 missiles, something from the object shot out and disabled his weapons system, his compass and his radio.
