美国新型飞机秘密基地：51区卫星地图

　　51区(Area 51)是一个大约155平方公里的地区，位于美国内华达州的林肯郡。它是广大Nellis Air Force Range（NAFR，美国空军训练设施）的一部分（12139平方公里），也是Emigrant山谷的一大部分。51区的北方是Groom山脉、南方是Papoose山脉，东方是Jumbled Hills。在整个盆地的中央是Groom Dry湖（坐标北纬37°16′05″，西经115°47′58″），这个湖是一个直径约5公里的干燥沙地。一个大型空军基地就位于该湖的西南角（坐标北纬37度14分、西经115度49分 ），它有两条水泥跑道，至少有其中一个跑道延伸进入沙湖之中，另外还有两条未准备的跑道直接建造在沙湖之上。

　　51区旁就是内华达测试基地（Nevada Test Site，NTS），它位于亚卡台地（Yucca Flats）上，与51区使用同一个行政划分线。它是美国能源部测试核武的地方，而亚卡山的核武储存设施就位于大约Groom Lake西南方64公里处。

　　长期以来，这里一直是UFO爱好者和指控美国政府一直在这一地区进行某种阴谋活动的批评人士希望了解的神秘地方。表面看来，“51号地区”就象是一个由飞机机库、储存仓库以及跑道组成的普通试验场。但进一步的观察却显示出令人很感兴趣的内容。第一个引人注目之处就是该地区南部一条长度超过3英里的跑道，跑道一边是好几处飞机库，其中几个外形非常巨大，屋顶都被漆成白色。第二个值得注意的地方就是一座空中交通管制天线，这座天线底座呈长方形，长400英尺，而天线本身高150英尺，所以在天气晴朗的条件下，从12英里以外都可以看到这座天线。

Here are the amazing aircraft of Area 51, listed in chronological order:
U-2 Spyplane: The first plane of Area 51. It was used to spy on the Russians before it was shot down in 1960.
Suntan: A plane powered by a liquid hydrogen engine, which could have been used to create the Aurora.
SR-71: The fastest plane in the world, not counting the X-33 (which isn't really a plane)
Soviet Aircraft: While not "Area 51" aircraft, the MiG 1.42 and the T-60S are the best fighter and bomber in the world.
Tacit Blue: This plane is the first to incorporate new stealth technology. Because of its stealth, it looks really strange. See it for yourself!
F-117: It's so stealthy, it has a radar cross-section the size of a marble.
Black Manta: We don't know if it exists or not, but it's rumored to be even stealthier than the F-117A.
Aurora: We don't know if it exists, but it is rumored to go from speeds of Mach 6 to Mach 20.
Brilliant Buzzard:
A very large plane that can actually launch smaller aircraft.
Stealth Cruise Missile:
Only has a small description, which takes a relatively long time to load.
Uavs:
Only has a small description, which takes a relatively long time to load.
X-33: A real plane-that-is-sort-of-a-space-shuttle that can go up to speeds of Mach 13!
F-22: This plane is a good combination of stealth and manuvurability which makes it as stealthy as the F-117A but more manuverable.
Switchblade: A plane with a swing-wing design, which allows it to go up to speeds of Mach 3, maneuver very well, and drop bombs.
