Lockheed L-1011 as modified by Orbital Space Corporation and Marshall Aerospace.
Pegasus and the Stargazer available here.
Here is a scaled version of the Lockheed L-1011 as it is used by NASA
in it's Pegasus rocket launch configuration. The model was scaled up
to 1:100 and required 10 sheets of 65lb cardstock to print the model.
This was required in order to be able to model the Pegasus rocket large enough
to have a decent amount of detail.
The Pegasus rocket model will be coming shortly.
