AIR PICTURE — CHAGRIN FALLS, OH — 2026-08-29
EXECUTIVE SUMMARY: Abnormally quiet day — traffic running 53% below the 7-day average, with a parade of absent regulars and a handful of contacts that warrant a second look.
NOTABLE TRAFFIC
N4K [A4A8D0] deserves a mention simply for style: an unidentified aircraft punching through at 41,000 ft and 570 knots on a heading of 075°. Fastest contact of the day. Nobody introduced themselves.
UAL1981 [A05627] clocked 546 knots eastbound at 38,975 ft — second-fastest of the day, doing its best impression of someone who just remembered an appointment.
QTR22B [06A123] — Qatar Airways heavy, 33,000 ft, 522 knots, heading 058°. Long way from Doha. Routine transatlantic routing, but worth logging the international visitor.
UPS1441 [A39F0D] was observed at 1,175 ft and 161 knots on a 048° heading near Medina — low, fast-ish, and consistent with a cargo approach to CLE. Your packages are moving.
TWY590 [A79DAD] — callsign and operator unfamiliar — cruising at 43,000 ft and 518 knots eastbound. Highest altitude contact of the day.
ANOMALIES
QTR22B [06A123] carries an ICAO hex (06A123) that falls outside all known national allocation ranges. Aircraft appears real; transponder code is not. Flag and monitor.
VTM527 [0D0FF1] and ANA102 [86D5B6] — same problem. Unknown hex codes, unknown operators. Three unallocated-hex contacts in a single day is three more than usual.
RPA4722 [A50192] and UAL2097 [A44962] flagged LOW_AND_FAST: 2,800 ft / 270 kts and 2,925 ft / 209 kts respectively. Neither altitude nor speed is alarming in isolation, but the combination earns a notation.
BAW19W and BAW8K — two British Airways heavies transiting the area. ICAO codes confirm UK registration. Routine, but foreign registrations logged per standing procedure. Canada also sent nine aircraft, because of course it did.
PATTERN NOTES
Today's 604 contacts represent a 53% shortfall against the 1,283-aircraft daily average. The deficit is not concentrated in any single operator — Southwest, United, Delta, Republic, and Endeavor all show substantial gaps in their regular rosters. No systemic cause is identifiable from air picture data alone; weather, NOTAM activity, or upstream scheduling disruption should be investigated through other channels. Missing regulars number well into the dozens. The sky was technically open for business. Business did not fully show up.
