Yeah I caught that. There were three separate TFRs stacked over the proving ground in a 10 day window which is unusual even by Dugway standards. Normally you get one and it's done.
What got me was the altitude ceiling on the second one - went up to FL600 which is way beyond what they'd need for a standard weapons test. That's SR-71 territory and above.
I've been cross-referencing with some ADS-B data from that period and theres some interesting gaps that don't match the published restriction zones. Someone was keeping traffic well clear of an area about 40 miles north of the main base perimeter.
Anyone in Utah who was watching the skies during that window? Would be good to get some ground level reports to go alongside the airspace data. This kind of thing is worth documenting properly before the records get quietly amended.
