KCPS — St. Louis Downtown Airport
No aircraft this investigation tracks has a recovered ground visit at this field; what follows are the airborne fixes that put a tracked aircraft in this airspace.
Claimed overlaps at this field that primary data confirms
Rows from the published overlap sheet whose claimed field this investigation's recovered ADS-B positions agree with. A closest approach measured with the aircraft airborne is an arrival, a departure or a low pass over the field — it is not a parked aircraft, and the table says which.
| Date | Claimed aircraft | Verdict | Closest recovered approach | On the ground? | Whose event | The claim |
|---|---|---|---|---|---|---|
| 2023-05-03 | SU-BND | AT_CLAIMED_AIRPORT | 2.07 km | no — airborne fix | Erika | OWENS-014 |
A confirmed field is not a confirmed pattern, and it places nobody aboard. The verdict says the recovered positions agree with the field the claim names. It says nothing about why the aircraft was there, and nothing about who was on it. Each row's own page carries its counterargument in full.
The field
Cahokia, IL. The recovered record for this field holds no ground visit and no flight leg by any aircraft this investigation tracks. That is a coverage fact about what the archives hold, not a finding that nothing landed here.

What this page cannot tell you
- Presence is not purpose, and it is not occupancy. No ADS-B record places any person aboard any aircraft.
- An absent day is not an absent aircraft. Volunteer receiver coverage is uneven, and a jet parked with its transponder off is invisible. Absence here is a coverage fact.
- Every count on this page is a count of the aircraft this investigation tracks, not of everything that used the field. Most aircraft at a general-aviation airport are flight-school and charter traffic, and many carry the FAA's ordinary Limiting Aircraft Data Displayed privacy flag, which is a routine owner filing and not a sign of anything.
- 2022 is effectively blank — no free archive covers it.
