Photo Notes: Here is a shot of the Hyper-X in flight yesterday. This is the "stack", which consists of the rocket booster portion, which is white, and built by Orbital Sciences Corporation, and the "flyer"
which is black, at the nose. The "flyer" separates from the booster at
high mach number in the atmosphere - a new thing - and then the cowl
door to the front of the engine opens and the engine stars and runs for
ten seconds or so. The SCRAMJET engine is the small black blob under
the flyer.
