Project 10073 Record Card — 5 March 1955, Anderson AFB, Guam

This document consists of a Project 10073 record card and a follow-up teletype message regarding an aerial sighting on 5 March 1955 at Anderson AFB, Guam. At 1435Z, witnesses observed a string of five lights, ranging in color from off-white to light amber, moving in a northeast direction. The objects were described as being in a train formation and equally spaced, ascending gradually over a duration of 30 minutes. The witnesses, including several military officers, noted that the objects appeared to oscillate irregularly. Upon reaching an overhead position, the objects appeared to merge into a single light before accelerating and disappearing. The initial report was subjected to an investigation by the unit. The subsequent teletype message, dated 8 March 1955, clarifies that the incident was investigated and the objects were definitively identified as balloons. Specifically, it was determined that five test balloons had been released by weather personnel for a theodolite check at 1445Z. The report concludes that the sighting was a misidentification of these meteorological balloons. The document notes that corrective action was being taken to prevent future erroneous reporting by the local meteorological facility.
