Great idea [emoji362]
When I shop for a pickup I always ask what kind of mileage the engine would get without the rest of the truck.

So I'll take a stab at making a RASP ENG file for the motor and then doing a OpenRocket and/or RASAero sim.
Like this?

You too? :eyepop:
I confess. It was meant to be humorous. [emoji851]
Perhaps you could add this to the Thrustcurve.org collection of motor thrust specifications:
https://www.thrustcurve.org/contribute.shtml
so others could do sims using this S-class Cesaroni motor.

I suspect they know that there are some really bad upper level winds on those days. Lotsa luck.
Jim
Is there a web page that specifically gives high altitude winds at the site?

This is my favorate site. You can get the forecast for almost anything by many of the weather models.

Winds for noon Sunday and Monday are attached. Not much mystery in this forecast.
Jim
Yes. They did.Thanks. Ill ask if they took that into account.

Unconfirmed reports are that the second stage didn't light. Speculation is that the high upper level winds changed the attitude of the rocket causing an automatic cutoff of engine ignition.
