AIR PICTURE — CHAGRIN FALLS, OH — 2026-06-21
EXECUTIVE SUMMARY: Exceptionally quiet day over the Falls — 223 contacts logged against a 7-day average of 3,242, representing a 93% reduction in traffic. Something is very much not normal up there.
NOTABLE TRAFFIC
THY6 [4BA949] — Turkish Airlines operating at 33,000 ft, heading 102° (eastbound). ICAO hex registers to the Netherlands, which is not unusual for Turkish-operated European-registered frames, but worth noting alongside today's broader anomaly picture.
PHGOV [485920] — Callsign "PHGOV," Netherlands-registered ICAO, cruising at 37,000 ft heading 069°. Government callsigns always get a second look. This one checked out in terms of behavior but the provenance is flagged.
TAP23SL [4952B0] — Portuguese-flag carrier operating eastbound at 37,000 ft, Netherlands-registered hex. Transatlantic routing consistent with position.
BAW6AC [4005C1] — British Airways, UK-registered, at 37,000 ft heading 066°. Routine transatlantic.
DHK384 [408143] — DHL freight, UK-registered, descending trajectory heading 225° at 34,000 ft. Cargo traffic holding up better than passenger today.
N951CP [AD389E] — Slow mover: 900 ft, 23 knots, heading 050°. That's helicopter territory. Probably not a threat, but it's practically at treetop level near the Cuyahoga Valley corridor.
QTR8151 [06A1ED] — Qatar Airways eastbound at 35,000 ft. ICAO hex falls outside known national allocation ranges. Flag retained.
ANOMALIES
Seventeen contacts transmitted no flight identification despite active Mode S transponders — altitudes ranging from 24,000 to 41,000 ft. This is not a trivial number. On a normal day, one or two ghosts are unremarkable. Seventeen is a crowd. No positions available for several of them, which limits assessment.
Three ICAO hex codes — QTR8151, CLX93D, SIA22, and AMX692 — fall entirely outside recognized national allocation ranges. Unknown hex origins at cruise altitude warrant monitoring.
PATTERN NOTES
Today's traffic is 93% below the 7-day average with no obvious single cause in the data. Regulars are absent en masse — UAL700, JBU135, multiple SWA and DAL schedules — suggesting a systemic disruption (ATC, weather upstream, or operational stand-down) rather than isolated cancellations. The flights that are present skew heavily toward transatlantic and cargo, which historically weather disruptions better than domestic short-haul. Low-altitude contacts (DAL1320, DAL1339, AAL1934) suggest approach/departure activity near CLE remains partially active.
