Ulh, as Roseanne Rosannadanna used to say, "Never mind!"
My spreadsheet opened to the 2nd tab (graph) i didn't notice the 1st tab
(all the data). I have now plotted altitude vs time based on the data and
there is no kink. All is well.

Dang it. The altitude graph can't be right :(
Sorry Eric, but can you generate a graph of motor thrust and see if it
looks reasonable? (Should be roughly parabolic until burn-out.)

Thanks Eric!
That is a funny altitude graph. What's up with the knee? Anyone know?
13 g's off the pad and then -7 g's at burnout... it'll be one of our
more wild rides :)

We have a preliminary simulation result.
Assumptions:
Launch Weight52.87 Poun
Robert of OROC wants a simulation of our flight before we get the green
light to fly. I think that means that Eric and Tim need to chat ASAP and
get that going in ALT4?
Thanks!
