This aircraft was from a book, V-S Day by Allen Steele, in which the experimental Silbervogel was actually built and launched once the allies learned of this the US assembled a team of experienced engineers and scientist one being Robert H. Goddard a very experinced rocket engineer, to construct a interceptor cabable of reaching space and destoying the Silbervogel, its only weapons were 2 missles filled with railway spikes because no air=no expolsions and the plan was to fire the missles let it detonate and the Silbervogel would fly into the spiked cloud destroyingit ,though I wasn't able to fit the missles but due to stability issues ( NOTE: turn RCN off with activator 8 at low altitudes you'll stall out if you don't,let it sit for a couple seconds at full throttle the hit activator 1)
