AIR PICTURE — CHAGRIN FALLS, OH — 2026-10-12
EXECUTIVE SUMMARY: Unusually quiet day over the Falls — traffic running 61% below the 7-day average, with anomalies of note in the low-altitude and transponder-silence categories.
NOTABLE TRAFFIC
UAL3812 — Westbound at 11,575 ft, 316 kts. Notably low for a United mainline contact; likely on approach or departure from CLE.
EDV5071 — Crawling northeast at 2,250 ft, 141 kts. Classic regional prop-speed descent profile, hugging the deck west of town.
SGX791 / ENY3375 / SGX435 — Three contacts in close proximity, all at 875 ft, all headed 050° at roughly 138–140 kts. Formation spacing or rapid sequencing; worth a second look.
N979CC — 875 ft, 91 kts, heading 238°. Slow, low, and wandering. Recreational traffic or a very unhurried departure.
OBD752 — Eastbound at 46,975 ft, 555 kts. Above standard commercial ceiling. Fast. Says it's nobody's business. Noted.
THY91J / THY181 — Two Turkish Airlines contacts passing through at altitude. Long way from Istanbul, but perfectly routine transatlantic routing. Flags noted for completeness.
ANOMALIES
[A43EEC] — NO CALLSIGN, 36,425 ft. Mode S transponder active; no flight ID broadcast. Altitude suggests commercial-class aircraft. Reason for silence: unknown. We're watching.
OBD752 [AA218B] — VERY HIGH ALTITUDE. 46,975 ft exceeds the standard commercial ceiling of 45,000 ft. Consistent with a large business jet or military profile. No other red flags, but noted with one eyebrow raised.
CLX98V [4D0128] / AMX692 [0D1030] — UNKNOWN HEX CODES. Both ICAO addresses fall outside known national allocation ranges. Peculiar. Could be data corruption; could be something else. Filed accordingly.
AAY1009 [AB6108] — LOW AND FAST. 2,975 ft at 244 kts. That's not a leisurely sightseeing tour over Chagrin Falls.
PATTERN NOTES
Today's 552 contacts represent a 61% shortfall against the 7-day average of 1,428. The missing-regulars list is extensive — over 200 entries across multiple operators (DAL, UAL, SWA, RPA, EDV, SKW). No single carrier accounts for the gap; this appears system-wide, possibly reflecting a weather diversion day upstream or a scheduling anomaly. Canadian-registered traffic (JZA, ROU, WJA, ASP, CJT series) remains present in normal proportions. A Saudi-registered contact (APZ135, ICAO 71C389) transited at 39,000 ft — unremarkable routing, foreign registration logged per standard.
