|Description||This is a parametrized model of the HL-20 Space Plane based on the 3view drawing and cross sections found in NASA TM-4117. Unfortunately, the drawings are clearly self-inconsistent. This is the best model possible based on clearly flawed source material.|
4 - The source material used to create this model was Inaccurate. This means some photos and drawings with very few dimensions were used to create the model.
