Claimed flights we could NOT retrieve a primary ADS-B trace for

This is the only free, no-account source of historical ADS-B tracks we have found. It serves only what its volunteer feeder network actually received.
WHAT AN EMPTY RESULT DOES AND DOES NOT MEAN. A 404 here means adsb.lol holds no
trace for that airframe on that UTC day. It does not establish that the aircraft
did not fly, and it does not establish that a transponder was switched off. The
ordinary explanations come first: the aircraft was parked and silent, it flew outside
volunteer receiver coverage (most of the Atlantic, most of North Africa, much of the
rural US at low altitude), or the claimed date is simply wrong. Several of the rows
below are already recorded in overlaps.csv as audited inaccurate.
The claim is what is listed. The absence is what we found. Neither is proof.
| Tail | UTC date | HTTP | Why we looked |
|---|---|---|---|
| SU-BTT | 2023-04-24 | 404 | overlap OWENS-049 - Wichita KS (audited_inaccurate, audit: inaccurate); overlap EXTRA-003 - Topeka KS (claimed, audit: untested) |
| SU-BTT | 2023-04-25 | 404 | overlap OWENS-049 - Wichita KS (audited_inaccurate, audit: inaccurate) |
| SU-BTT | 2023-04-26 | 404 | overlap OWENS-049 - Wichita KS (audited_inaccurate, audit: inaccurate) |
Where this page fits
Three HTTP 404s for SU-BTT across 24-26 April 2023 are the whole of this page, and they are published so the Wichita row is filed as untestable rather than counted beside the rows the overlap index actually resolved — the free archives do not reach spring 2023, as the Wichita location record and the 73-overlap reconstruction both note. The distinction matters well past aviation: the same reasoning governs how this site treats withheld foreign flight records, evidence sealed until 2026 and the halted foreign-nexus review — a missing document is a gap, never a finding. To see that principle cost this investigation a headline, read what a 403 actually means: a published removal claim was retracted after five unrelated control aircraft returned the identical refusal, and flight data recovery sets out the control test that caught it.
