Unidentified

On the public record, and still open. A claim, paper, or film — not a finding that it was ours, and not a finding that it was not.

Crew debriefs, radar data, and ECM recordings from official files.

What was claimed

A USAF RB-47 crew of six experienced a 90+ minute encounter with a bright light tracked visually, on airborne radar, ground radar, and electronic countermeasures equipment across multiple states. The object repeatedly appeared, disappeared, and maneuvered at high speed. Studied by the Condon Committee.

What is on the record

This file is a working record — a report, not a verdict. Official paper, if any, is linked where we have it.

In the early morning hours of July 17, 1957, a six-man crew aboard a USAF RB-47H electronic reconnaissance aircraft flying from Forbes AFB encountered an unidentified object. First detected by ECM gear over the Gulf of Mexico near Mississippi as a strong signal, it soon appeared as a brilliant white-blue light to the pilots. The object was simultaneously tracked on the plane's radar and by ground radar stations. Over 1.5 hours and hundreds of miles, it paced the aircraft, accelerated rapidly (up to 1,000+ mph), performed sharp turns, and appeared/disappeared on all three independent sensor systems at the same moments. The crew included pilot Lewis Chase and ECM officers; the case was left unexplained by Blue Book and the Condon Report.

Could this have been ours?

The known sky, that night.

Satellites were already up. The station was not. Starlink was not.

Always

Venus and the bright planets

A fixed brilliant point. Does not streak. Does not hover over a street then leave. Often the first misread light in a rural report.

Always

Aircraft, balloons, meteors

Landing lights, flares, lanterns, reentries, fireballs. They are on the known sky. They do not close a file by themselves — they are what a serious look has to hold the claim against.
