The 3 ground segments on this day
The aircraft did not sit still between these. A break between two runs of on-ground positions at the same field means it took off and came back — not that it waited on the ramp.
| # | Ground window (UTC) | km from field | On-ground fixes |
|---|---|---|---|
| 1 | 14:53–17:13 | 0.75 | 255 |
| 2 | 16:10–16:13 | 0.28 | 49 |
| 3 | 17:07–17:13 | 1.28 | 58 |
Two independent routes hold this contact. One asked where was this tail on this day; the other streamed a whole day of the open archive and filtered it by geography without being told what to look for. They agree.
What this establishes, and what it does not
It establishes that the airframe was there. The positions are on-ground reports from a volunteer receiver network, held in a public archive, and recorded here with the exact window they cover.
It does not establish purpose, and it does not establish occupancy. No ADS-B record anywhere places any person aboard any aircraft. An aircraft near an event is an airframe near an event.
And for this aircraft, proximity is the expected thing. This is a Kirk- or TPUSA-associated airframe. An aircraft that carries the man showing up where the man is is not surveillance — this row is a check that the method works, not evidence of anything.
