Matt Johnson's Cosmostrator, me hearties, modified for one launch rod. Ya scallywag! Matt previously tried a three launch rod construction, but it was too difficult t' align t' rod, so Joe Mosher o' SMASH suggested he modify t' rocket for one launch rod, shiver me timbers, right though t' center. T' nose cone be hinged t' flip back into place after t' rocket left t' rod, matey, but t' whole rocket flipped!
