Standing
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.
What was claimed
A glowing object was seen to strike a hill known as Height 611. Residents recovered slag-like metal and mesh. Soviet investigators collected samples.
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.
On a winter evening, people in Dalnegorsk watched a reddish object descend and hit the rocky hill above town. There was no conventional crater. Schoolchildren and adults picked up silvery drops, a carbonaceous slag, and a fine “net.” Chemists in the Soviet Far East reported unusual lead, silicon, and rare-earth ratios; later papers argued for industrial residue and a failed military device.
The hill is still walked. The samples exist in collections of uneven provenance. The file is a small-town impact without an airplane, in the last years of the USSR.
Could this have been ours?
The known sky, that night.
Satellites were already up. The station was not. Starlink was not.
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.
The known sky
None of the above land
Stations, trains, and planets do not set down in a field or leave a body. This file is a ground report. The known sky still has to be named. It does not answer the claim.
