I created a silo launch ICBM. It has a open/close blast door, and this rocket hostages. Here are some pics.
Blueprint
Ready for launch
Launch
Hotstageing
In order to hostage, press the atageing button when the first stage has about 2 percent of its fuel left. Then right as it runs out of fuel press the button again to release the second stage.
Preparation for launch
In order to open the blast door, click the structural pieces right next to it, then press the stageing button and the rcs on the door. Then just swing it away. After launch you can also close it by doing the steps in reverse.
After you have opened the door, click in the middle of the silo to control the rocket
Congrats you are ready to launch. Just press the stageing button to launch the rocket.
Here the B.P.
