AIR PICTURE — CHAGRIN FALLS, OH — 2026-09-20
EXECUTIVE SUMMARY: Dramatically quiet day — traffic running 72% below the seven-day average, with 448 contacts logged against a baseline of 1,572. Whatever is keeping aircraft on the ground today, it is working comprehensively.
NOTABLE TRAFFIC
The high-altitude prize goes to N408LS [A4CB64], cruising at 45,000 ft on a 115° heading — right at the ceiling of standard commercial operations. Purpose unknown; manners impeccable.
UAL1818 topped the commercial stack at 38,975 ft eastbound, while SCX9002 ran 40,000 ft westbound — both unremarkable except for their altitude discipline.
Down low, JZA735 [C035BB] and RPA4379 [A4C527] were both observed below 900 ft on nearly identical headings (050°) in the same general vicinity — two contacts in close altitude proximity warranting a second look, though approach sequencing likely explains it.
N9443L trundled westbound at 5,975 ft and 83 knots. Presumably enjoying the scenery. No objections noted.
ANOMALIES
ANVIL77, ANVIL78, ANVIL79 [AE695C / AE6910 / AE695E] — Three contacts squawking US military hex codes, appearing in formation callsign sequence. No altitude data in the feed. Their business is their own, but they showed up, and we are noting it.
AAL3146 [AD3C16] logged at 2,825 ft doing 251 knots. Low and fast. The system flagged it; we concur it is worth a raised eyebrow.
JBU1341 [A392F2] similarly flagged at 2,950 ft / 231 knots. Low and fast, with no further detail available.
EIN9LT [4CABD2], VTM527 [0D0FF1], EVA003 [89907D], and 00000000 [0D0FA2] all carry ICAO hex codes outside any known national allocation. Four unknowns in one day is above average for the unusual category.
Foreign registrations from Canada, the United Kingdom, and Germany transited the area without incident. BAW8K [407AF1] — a British-registered contact at 37,000 ft — is the farthest-traveled guest on today's roster.
PATTERN NOTES
Traffic volume is the story today. The deficit against the seven-day average is severe and consistent across all observed hours. Over 300 regular flights failed to appear. No single carrier accounts for the absence — DAL, UAL, AAL, RPA, SWA, and numerous regionals are all underrepresented. A system-wide disruption, weather event upstream, or data feed degradation cannot be ruled out from this post alone.
Recommend cross-referencing with adjacent sectors.
