I did a search on WWW and nothing came up so I figure I give it a shot…
It seems like they have daily 20 minutes flight to “Tonopah Test Range” with no ATC history and/or tracks. I wonder if this is one of the Dreamland flights.
It pretty much isn’t, however it is for the government. Dreamland/Area 51 is pretty much public now, as they’ve designated the airport KTXA and named it “Homey Airport”. This is pretty much just a set of ferry flights up to the test KTNX for various bits of work. The Nevada Test site had some things going on up there, but other than that, there isn’t much going on up there that isn’t USAF related. Apparently, it’s Silverbow, according to the remarks.
If you look at a Google Map of the airport, you can see 2 Janet 737 parked on the ramp, along with a Beech 1900 or maybe a 200. Can’t get close enough to tell.
TNX shows a single 737 on the ramp, but LAS shows 5 737s and 2 1900Ds on the “Janet” ramp. Interesting note about TNX, if you look just east of the parallel taxiway, you’ll see a double fence line that parallels the taxiway. Each taxiway spur has gates that block access into the inner secured area, specifically the hangers, operations buildings, etc… The Janet terminal at TNX is outside the inner perimeter, since pax are going to have to undergo security checks at their work location anyway.
Just because the locations aren’t a secret anymore by no means diminishes the fact that what goes on at these facilities is extremely sensitive and very closely guarded from prying eyes.
