The wing design looks like it was inspired by SpaceShipOne. The wing design makes me think this was proposed in 2010 or earlier.
I don’t know why they needed the propellers or turboprops or whatever those are. It could have glided to a runway without engines.

I know the engine’s the expensive part but it still seems wild to go to so much effort you literally build a *plane* around it, and throw away the booster, when like… the engine + booster is already a functional aircraft!

Using solids shows that this is rather an attempt to build Ariane 5 again with this reusibiliy thing someone was nagging us about rather than a well thought design .
Solid give you trust at launch. You need it because the engine is expensive. But if you can recover the engine, suddenly the trust and launch is cheap. They boost your MECO speed so your recovery is harder. Going with solid 2nd stage and hydrolox 3d would make more sense.
