Back in Bloggin' Bidniz

Folks, sorry for the bit of a hiatus.  Had quite a good work load there since February, but now I’ve got some time to provide some blog posts.   In terms of Blog posts, here’s what I’m working on:  

1.  2^nd part of ATR history  

2.  2^nd part of ATR applications (sub-orbital and orbital launch vehicle applications)  

3.  simplified ATR performance calculation tool  

4.  More blog posts on Exvionmentalism    

We’ll see how those actually pan out.  Stay Tuned.
