Masten Space is preparing to do tethered tests of their Xombie rocket vehicle. Ian Kluft has posted several pictures in his Twitpic gallery. See, e.g., here and here.
Update: Dave Masten says on Twitter
> Xombie flew today. Flew on a tether for crew proficiency.
He also posted this photo.
It appears they are practicing with Xombie before flying this new rocket.
