Lunar Lake, 2013...

Flight Center IV or "Area-B", is our Nevada base for operational production military aircraft. Area-B is to Area-A what a normal Air Force Base would be to Area 51. It's where we fly military planes of every conceivable type, our own designs included.

Captured MiG-21, Area-B -- 1999

Back in FS98 I was on the hunt for my own private "Area 51". I had picked three dry lake beds in central Nevada - one at Lunar Lake in Railroad Valley, one in Kawich Valley, and one at the extreme south of Railroad Valley on the Wilson Salt Flat. During FS98 those bases became Area B, Area C, and Area A, respectively. Area C was never really pursued, and was abandoned after FS98. Area B eventually became Flight Center IV.

AFC4 is loosely based off of the High-technology Aerospace Warfare Center (or HAWC) from the earliest Dale Brown novels - Flight of the Old Dog, Day of the Cheetah, Sky Masters, etc. (He uses the word Dreamland frequently, which suggests Area 51. But being a novel, and susceptible to the readers imagination, I always thought of it as some other place)

Area-B Version 1, 2003

Though it originated in FS98, it wasn't until FS2002/CFS2 that this base had a dedicated central role - weapons development. During CFS2 this base was used as a place to create new weapons for that sim.

To date, it is our only scenery that is also compatible with CFS2.

Version 2 FSX
(RRV2013 Package)
- 30Mb

Since Microsoft hasn't made a combat sim lately, Area B has sort of been limited as far as actually using weapons are concerned. But it still retains it's "weapons depot" look and feel. The entire Railroad Valley scenery area has undergone a bit of an upgrade since Area B's first release. A second version for FS2004 was planned but Area-A took so long that neither scenery ever got released. The positive side of this is that many new additions have been added to the whole area.  There is now a bombing range in the mountains to the north of the Lunar Lake base, and out in the Valley there is a massive dry lake bed where we have a "skid strip" with runways varying from 4 to 11 miles long, where we tested the SV Class shuttles we built originally for Battle of the Airlines 2003. Also there is a small space launch site in the middle of the Valley, directly north of Area A and directly east of Area-B for unmanned space missions in the Orbiter Space sim.

For FSX we release Area-B, along with our oldest and largest scenery Area-A in  Railroad Valley 2013, a full scenery download including both airports (and many more ouposts) all in the same package!
