I had a similar memory of a kit that i loved as a child, but could NOT find anywhere. Ilooked on the net, but not remembering the name of the thing. Anyway I was cruising through the Fantastic-Plastic website one night and found it! It was one of the last Aurora subjects, called the Ragnarok, a nuke powered anti UFO vehicle that carried a parasite fighter in its tail to prevent the onset of maruading alien invasion fleets.
It was a great kit, sleek and pointy, with a cool yellow disk in the top of the fueselage.
here is a link to it, check out the rest of the site as well, its a great trip through memory lane!
