  1. Are there plans to restock that model XD?

  2. Starship Captain

    Did the FAA delay Starship launch to orbit with Raptor? Or was SpaceX not ready or did Elon decide to accelerate Raptor 2 because of the delay?

  3. It always strikes me how small rocket engines are when you see them in person, or have someone standing by them for reference.

  4. Amazing video Tim!! You have come so far with what you do! Your videos are top notch! Can not wait for the raptor video!

  5. Yes, yes, yes! This is good content.
