Hence the need for Top Secret test areas like the one about 90 miles north of Las Vegas. The hypersonic aircraft hasn't been tested there because there are no launch facilities (yet) to accomodate its insertion into sub-orbital flight. As for the stealth bomber (I'm assuming you mean the B-2), those were
tested, along with the F-117F/B and the B-1B, at the Groom Lake facility and the other test range about 200 miles north of Las Vegas.
