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.
