Hi, not sure if this belongs here, but I just found this one: A Boeing 727 belonging to an oil spill response company doing a racetrack pattern over the Irish Sea... https://globe.adsbexchange.com/?ica...691&zoom=8.8&showTrace=2021-09-27&trackLabels (if you zoom in on the racetrack on the left hand side, you can see it's flying below 500 ft, with less than 150 knots in some parts of the pattern...)
