AIR PICTURE — CHAGRIN FALLS, OH — 2026-10-15
EXECUTIVE SUMMARY: Significantly quiet day over the falls — traffic running nearly half of normal volume, with a crowded anomaly log and enough missing regulars to fill a small airport.
NOTABLE TRAFFIC
The high-altitude parade was led by TWY429 at a commanding 45,000 ft, pushing 566 kts eastbound — the day's altitude champion among routine contacts. UAL1950 and DAL683 were also moving briskly in the mid-500s knot range at cruise altitude. On the international flavor side, EVA004 (Taiwan-registered, ICAO hex in unallocated space — noted separately) was tracking southeast at 39,000 ft. Low and slow honors go to JIA5099 at 1,125 ft northbound and KSF40 puttering along at 3,800 ft and 118 kts — likely the most relaxed pilot in the airspace today.
ANOMALIES
MILITARY CONTACT — VADER82 [AE779F]: ICAO hex falls squarely in US military allocation range. No altitude or speed data in the record. It showed up. That's all it wanted us to know.
VERY HIGH ALTITUDE — N550DA [A6FFB7]: Reported at 47,000 ft, above standard commercial ceiling. No position data present in today's contacts. Big jet or something that prefers not to be questioned.
UNKNOWN HEX CONTACTS: Five ICAO hex codes — EVA004, EIN9LT, EAU56D, VTM293, VJT765, AMX025, AOJ95S, QTR8807 — fall outside known national allocation ranges. Nothing overtly threatening, but the transponder homework is incomplete on all of them.
FOREIGN REGISTRATIONS: Canadian-registered traffic was active and varied — Air Canada (ACA), Jazz (JZA), Cargojet (CJT), and others. Spain contributed two contacts (EVE816, IBE0312); Germany one (BCS378); the UK two (DHK058, DHK007); China one (B653A at 43,000 ft). Somebody's globe is getting around.
LOW AND FAST: Four contacts — MXY1335, SKW5982, NJM900, AAY967 — were flagged under 3,000 ft moving 215–228 kts. None are in the current contact list, suggesting they transited and departed before the snapshot.
PATTERN NOTES
Total traffic at 709 contacts (644 unique) sits 48% below the 7-day average of 1,362. The deviation alerts fired repeatedly throughout the day — this wasn't a momentary dip. Dozens of well-established regulars across Delta, United, American, Southwest, SkyWest, and regional feeders are simply absent. No single obvious cause is apparent from the data. The sky was open; fewer chose to use it.
