The 2 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 | 00:16–00:17 | 0.51 | 58 |
| 2 | 15:38–16:11 | 0.5 | 223 |
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.
