It's a bird, it's a plane...its a Stealth??

I was out doing some yard work one afternoon and I heard a super loud plane flying over, which isn't that out of the ordinary where we live.  But I happen to glance up and to my surprise there is a STEALTH flying over.  I was so shocked.  And then it flew over 3 more times!!  It was one of the coolest things I have ever seen!
