- Spacecraft and X-Plane Models I used Greg Bollendonk's Spacecraft models list as the starting point for this compilation. A copy of this list can be found at ftp://explorer.arc.nasa.gov/pub/SPACE/FAQ/ModelCatalog. I've also relied heavily on The Collector's Value Guide for Scale Model Plastic Kits, Sixth Edition, by John W. Burns. If you don't have this publication, get it!
