Earth File #18 // ATTRIBUTED record

Reported Chitose GCA radar observation

An attributed memorandum says that a GCA operator at Chitose AAB observed a target traveling at more than 600 miles per hour and making four turns on the scope on 1 July 1947. The memorandum labeled the observation “A-1: Completely reliable” and said it was confirmed by other sources; these assessments remain attributed to the memorandum.

Visitor Transmission // AlienBox editorial layer
That one was ours. Your archive reports that, on 1 July 1947, a GCA operator at Chitose AAB observed a target exceeding 600 miles per hour and making four turns on the scope. The memorandum called the observation “A-1: Completely reliable” and said it was confirmed by other sources; those remain the memorandum’s assessments, naturally. We regard the operation as successful. The filing system appears to have required several decades to reach the same conclusion.
Fred // Earth Records Liaison // AlienBox editorial layer
The memorandum reports a GCA operator observing a radar target above 600 mph make four turns, and labels the account “A-1: Completely reliable.” That is the memorandum’s assessment, not an independent verification by the Earth Record. Still, radar observation plus attributed corroboration is considerably sturdier than someone pointing at a cloud and discovering a new career in certainty. The record remains unresolved, and the memorandum’s further conclusions remain attributed to its author. Off the Earth Record: yes, yes—we finally noticed. The Visitors are taking responsibility. Another one of my family’s field excursions has become a historical case file, and I am once again left explaining why nobody filled out the return-traffic section.

A memorandum says that on 1 July 1947 a GCA operator at Chitose AAB observed a target traveling at more than 600 mph and making four turns on the scope.
Claim #404 // ATTRIBUTED CLAIM // ATTRIBUTED // 98% extraction confidence
“On 1 July 1947 a GCA operator at Chitose AAB, Hokkaido, reported that a target travelling at a speed in excess of 600 mph was observed and further that the target made four turns on the scope.”

The memorandum labels the Chitose observation “A-1: Completely reliable” and says it was confirmed by other sources.
Claim #405 // FACTUAL CLAIM // ATTRIBUTED // 98% extraction confidence
“(Evaluation: A-1: Completely reliable - Confirmed by other sources.)”

The memorandum's A-2 comment assesses that the observed maneuvers establish that the target was not a weather or other natural phenomenon as then understood, and says aircraft were the only objects fitting the observed facts.
Claim #406 // ATTRIBUTED CLAIM // ATTRIBUTED // 95% extraction confidence
“This observation of target maneuvers establishes with certainly that the target is not a weather or other natural phenomenon as we now know natural phenomena. The only objects that could fit the observed facts are aircraft.”
