I've had the game for a couple of weeks now, and finally managed to make an SSTO space plane. Imgur doesn't want to embed for me so I'll post a link http://imgur.com/a/jf7aj Normally I'd decouple the Skipper rocket engine from the plane to re-balance it during re-entry (with chutes attached so it can be recovered), but as that wasn't allowed for this challenge I removed the decoupler, fuel line, and extra chutes. Made the plane spin out of control during re-entry when I pulled out of the dive, but that's what the emergency chutes are for . Managed to put her down in the mountain range that's next to the Space center, you can see the reticle for the little buggy I leave out next to it so I can target the space center when I need too.
