Space 1999 Hawk.
Just unzip directly to your Orbiter folder.
Only one basic landed scenario is included. Even though the Hawk has no landing gear, it sits about a metre off the ground.
If you have Moonbase Alpha already installed, the Hawks position in this scenario should put it on Pad 3. However I have only tried this in an Old 2005 version of Orbiter, so I cant be too sure about that.
This add-on requires Vinka's Spacecraft 3 DLL, which I have also included. Many thanks Vinka.
