From 1981-2011, in the event that a space shuttle had a failure going uphill during ascent, NASA selected several sites to be used as abort landing sites in such events. Fortunantly a space shuttle never had to be forced down in the event of a engine failure uphill. Now, you can recreate a fictonal abort with your own missions.
Includes Istres, Easter Island, Moron, Banjul, and Zaragoza base textures.
No addons are necessary, but I do recommend having Shuttle Fleet v.4.8 and the SLC-6 addon found on Orbithangar.
Enjoy!
