i cant spawn it it says contenset lock or

I agree, the flight broke the VAB(tallest building):(

First of all thank you for offering your creation. As an objective criticism, I must say that your designs of North American spy shuttles have serious flaws. I have 17 attempts to launch both shuttles, alternating automatic control systems and several climbing techniques, but it is impossible to overcome the 5000m altitude.
The most serious thing is that the angular design of the propulsion of the shuttle is not compensated by the center of gravity of the launcher, this causes an extremely slow and dangerous ascent rate of about 10º. Also, assuming that you pass the barrier of 5000, which is the most dangerous stage, when uncoupling the solid fuel engines, the ejector system makes them hit with the wings of the shuttle, causing reentry to be impossible. Thanks and best regards.

But, Can you make the Buran Space Shuttle?

I don't have any part mods installed, it must need the making history dlc.

I need a mod or something like that... dont have the parts for it... you have making history?
