Look in south direction of this place. About 2km south. There is bigger surprise than B2. You could see new X-32 the only on prototype of this stealth fighter.
I although found old U2 spy aircraft 0,5km west from the B2 and F-177 fighter 0,85km north west from the X-32. Found although some kind of former experimental plane 1,25 west from B2 plane but I forgot it's name.
That air base looks like especially prepared to test and repair special military aircrafts because near the place the B2 bomber is standing are situated special concret positions to test jet engines.
