Orion III With Boeing 747-400

Here are some images of Moebius Models Orion III from 2001 a space odyssey riding piggyback on Revell's 1/144 scale Boeing 747- 400 airliner.

One often sees images of the Space Shuttle riding atop of a Boeing 747. So I wanted to see how the Orion III shuttle would look.
Though they are not the same scale I think they look pretty good together.
