Hi new Higher detail and reshaped External tank for STS-1 and STS-2. Remember to rename or backup your orginal meshes, the textures are the orginal textures with Shuttlefleet so need to copy them but enclosed just incase  need to learn how to reshade DDs,s as there is a line down the underside of the tank but that is wwith the orginal texture  The burnt Tank on Sep seems to look fine to me.
Thanks To Martin and David 413
