So the analysis does take into account launch angles. But, what’s the
maximum angle? Wow, than a high launch angle and altitude could take your
rocket out of even Black Rock and it would be acceptable? I've heard that in
the future FAA is interested in roll control. I wonder why and if launch
angle (intended and true) would be important.

This is an interesting problem, and a solution would help many people.
Really, what’s the use developing a complex ‘splash’ analysis for a high alt
flight if you don’t even know what direction the rocket will be going 20’ off
the ground! And, if you are off 5 degrees at that point, it makes a lot of
difference where your rocket is going to be at +10K’.
hi Richard, not picking on you tonight, really :) Splash analysis is a
"monte carlo" simulation, many many flights with all parameters varied, such
as launch angle, wind speed and direction, motor variability, etc. at the
end you can say with great statistical confidence that the rocket really will
fly and land somewhere on the splash chart.
