VSS Unity First Powered Flight - Virgin Galactic

image manipulation caught at 42 seconds, notice there is what appears to be a solid black shadow protruding from the engine aft nozzle in the shape of what i expect to be the flame from the exhaust gasses but i believe the computer program didn't know how to deal with the light sources, and if you put it on super slow mo, (YouTube slowest setting), you can clearly see where they have stitched the overlay fake flame image into the ship image, because there a great big line running directly up from the edge of the flame start point vertically up the screen, TUT TUT lol call me crazy but you cant see a solid black shadow on a flame, no matter where the light source is coming from ;)
