They've flown one out of Boeing field here (it roams the country I believe) called "Aluminum Overcast". Watched it fly overhead several times on the way to work / and on the weekend. Thought it was stalking me lol
I'm going to snag tickets next time it comes to town, you can get a flight around the area in it.
Its currently down in Texas if anybody wants to check it out. You get to roam around the plane in flight, go to the gun positions, etc. Looks like fun!
