Can be build completely out of Lego bricks.
About the MOC
This is a MOC of the X-33 launchpad. It is compatible with my X-33 spaceplane MOC. The launcherector and the launchtable for the X-33 can be independently errected (the erector does need the table to be deployed too though).
About the launchpad
The X-33 launchpad is a site at Edwards Air Force Base in California.
