+7 grain 75mm sorbitol motor with pyrodex pellet ignition in 4-inch Wildman
+rebuilt airframe flown on 2 September 2018 at Airfest in Argonia, KS.
+
+CTI Pro75 6xl case, Loki #50 (long) nozzle with 2 o-rings, CTI forward and aft 
+closure rings, forward bulkhead from Terry's pile machined to have 0.5" inside 
+snap ring plus 0.25" inside liner, with two o-rings, one pushing against liner.  
+Original simulation says this should be a a 34% M-2293 with 6520 Ns total 
+impulse, 1056 psi max, 76% volume loading, and about 2.25 seconds burn 
+time.  After casting and weighing the grains, the adjusted simulation says
+this will be a ...

+## Results ##
+
+Flown at Airfest in Argonia, KS, off Terry's launch trailer.  Motor cato'd
+about 0.45 seconds after launch, blowing forward closure through the ebay
+and ripping the forward end of the case apart violently.  Clearly a 
+significant over-pressure event.  Pretty sure this was the first time I
+actually few the Pro75 6xl case with KNSB, and I dialed up the max pressure
+at the same time... which was clearly a bad plan.
+
+The burning grains were sent up in a fireworks-display-worthy fashion,
+generally acknowledged as the most impressive-looking CATO of the weekend.
+
+Flight data logged as sn 3121, flight 5, stored in cato.eeprom.
