Atlas F Launch Sequence

@DarkPK The side boosters use the methane/LOX mixture while the main engine uses kerosene and LOX. I did that so the boosters would run independently of the main engine. The Atlas had 2 side boosters and 1 sustainer engine. The boosters would shutdown and be ejected while the sustainer burned for a designated time.

Did you use Engine Overhall mod for this rocket? Because I noticed the side boosters' exhause had some purple color. (sryy for my bad English)

This is video of the launch sequence of an Atlas F ICBM. I will upload this project for your use.
