These are the ones I posted that I believe are the pattern you are looking for ~ posted several versions ~ AF1 on radar, but not visible, etc ~ let me know if you need more!
yeah, I"m aware ~ the twin otter in the area is the pattern!
trying again ~ these are for twin otter that was up when AF1 was up ~ the twin otter flew the semi-circle pattern ~ sorry for confusion ~ got to catch a flight shortly myself!
