Mate, ". Zero explanation". Is just the FAA's way of saying ". Loads of explanation, just not for you." 👀
Honestly this tracks perfectly with the pattern we saw back in 2019 over the same corridor - sudden TFR pops up, lasts 72 hours, disappears like it never existed, and FlightAware just quietly scrubs the anomalous traffic data afterwards. I've been cross-referencing these restrictions against DUMBs mapping projects on here for about two years now and the overlap is not coincidental.
What gets me is the altitude ceiling on this one. Standard military exercise TFRs cap out around FL180. This one apparently extended to FL600 which is effectively space. You don't need that kind of clearance for a drone exercise. You just don't.
A few things worth checking if you haven't already:
NOTAM archive - grab the raw data before it cycles out of the system, Cross-reference with any seismic readings from Nevada Seismological Lab around the same dates, Check amateur radio operators in the area - they sometimes pick up unusual UHF traffic during these windows
The Men in Black connection angle is interesting too because there were three separate reports on a Nevada forum of unusual black SUV convoys on Highway 93 the night before the restriction appeared. Classic pre-operation ground clearance behaviour.
Anyone got eyes on the actual NOTAM number? I want to pull the issuing facility data - that alone sometimes tells you more than the restriction itself does.
