Project Blue Book Sighting Report — Morgantown, Pennsylvania, February 14, 1967

This document contains a detailed UFO sighting report submitted to Project Blue Book by a civilian living in Morgantown, Pennsylvania. On the evening of February 14, 1967, the witness observed an object moving from east to west over an eight-minute period. The witness initially described the object as an orange fireball, which later changed into a three-light triangular configuration (white, green, and ruby red) and subsequently into a U-shaped crescent of non-blinking ruby red lights. The witness performed extensive mathematical calculations to estimate the object's size (258 feet), speed (530 mph), and altitude (12,629 feet) based on sound lag and visual observations. The witness also noted a loud motor sound, similar to a four-engine propeller aircraft, which was heard only after the object had passed. The report includes detailed diagrams and geometric proofs used by the witness to support their findings. The official response from Project Blue Book, dated March 10, 1967, acknowledges the witness's report and calculations. The evaluator suggests that the object was likely a jet aircraft climbing out of an airport, explaining that the 'very bright light' was likely a landing light used as a warning to other aircraft, and that the light configurations were consistent with the normal running lights of a jet seen from various angles. The evaluator concluded that the sighting did not warrant further investigation.
