My first interest in programing, outside of the simple office automation scripting I was doing, started when I built an orbital rendevous calculator in KSP (back before they had orbit planning built in).

I eventually merged my mod into mechjeb, adding a whole slew of orbital calculation functions, and many fun space times were had by all.

Thank you for contributing! I love KSP, and Mechjeb helped me get past the frustrating stage of learning the basics. I usually only use it for TWR and ΔV now but I think I'd have given up without it at first.
