AIR PICTURE — CHAGRIN FALLS, OH — 2026-05-27
EXECUTIVE SUMMARY: Significantly below-average traffic day — roughly 63% fewer aircraft than the 7-day norm — with a healthy collection of foreign registrations, several military hex contacts, and at least one contact apparently operating from the thermosphere.
NOTABLE TRAFFIC
- UAL102 [AA92F9] — United heavy, 35,000 ft, 556 kts, heading 54°. Fastest contact of the day. Going somewhere in a hurry. - AFR159X [39C423] — French-registered, 37,000 ft, 560 kts, heading 62°. Flagged as matching a government/military callsign prefix. File under "interesting but unconfirmed." - BAW171 [406D7A] — British Airways, UK registration, 11,075 ft, heading 246°. Descending or departed low; either way, the Crown is present. - CGOEI [C06A11] — Canadian registration at 45,000 ft, heading 53°. Top of standard commercial ceiling. Whoever this is, they're traveling in style. - N247WE [A24BF9] — 41,000 ft, 570 kts, heading 91°. Fastest-moving contact in the display. No anomaly flagged, just quietly impressive.
ANOMALIES
- CXK147 [A23A06] — Contact at 84,100 ft. That is not a typo. Standard commercial ceiling is 45,000 ft. Whatever this is — U-2, SR-71's spiritual successor, or a very optimistic altimeter — it was up there. - DAL573 [A8E1F6] — Reported at 67,100 ft under a Delta callsign. Delta does not operate aircraft certified for 67,100 ft. Likely a transponder fault, but noted. - VICE07 [AE602A] and G18096 [AE52D7] — US military hex range. No further details available. Noted with appropriate professional indifference. - VADER91 [AE77A0] — Military hex. The callsign choice is someone's doing, not ours. - [C0012F] — Canadian-registered contact, 46,575 ft, no callsign broadcast. Mode S active, identity silent. Politely mysterious. - PPABY [E4A537] and VTM527 [0D0FF1] — ICAO hex codes that don't match any known national allocation. They were here. We don't know whose they are. - DAL1418, DAL1207, DAL876, and several others — Multiple contacts flagged low-and-fast (sub-3,000 ft, 200+ kts). Likely on approach to DTW or CLE; still worth logging.
PATTERN NOTES
Traffic ran 63% below the 7-day average throughout the day, bottoming out near 75 contacts in the early hours and never fully recovering. The missing-regulars list is extensive — hundreds of expected flights from AAL, DAL, UAL, SWA, and RPA simply did not appear. No obvious single-carrier disruption; the shortfall is broad-based. Canadian traffic (Air Canada, WestJet, Jazz, and assorted CG-prefix general aviation) was present in normal variety. The transatlantic stream — British Airways, Air France, Lufthansa, KLM — appeared in expected corridors at cruise altitude.
Memorial Day holiday effect is the most probable explanation for suppressed domestic volume. The sky was quieter than usual, but not empty.
