Got it done, Glen is gone! Since I had the chance to take a pro video guy up for the event, I did, a somewhat infamous one but he knows his video work for sure. I will post a link to the video when he gets it edited down. 3 or 4 cameras were involved, plus a drone.
Bottom line: we landed with an empty tube, and none of it came in the plane, not even close. This is what jury struts are for I guess. There was a little light powder on the back side of the rear valve, kind of like how a car's backside get's dirty, but the ejection of the main tube was 100%. Both valves were opened at once, and like in my fireplace ash test, there was a large initial event, then nothing, then a few minutes later another large POOF, with some minor streaming in between the two big poofs. We flew for another hour before landing, a nice day and just looking around, which just seemed like a good idea. As did dropping the nose and letting the speed build to a whole 96 mph indicated.
I already had in the shop's junk drawer, a 3 by 4" no hub adapter (the rubber type) so I stuck it on the front to serve two purposes: to act as a funnel for the ash insert, and to theoretically increase the aero push thru the tube, mostly because I had it already. After I safety wired the rear valve shut, I dropped it off at the deceased's place, with a note saying to let me know when it was loaded up, so easy/peasy on my part. I was a bit surprised of the weight involved, maybe 8 or 10 pounds? 145 pound person. Don't know if this will be on the video, but out of nowhere, when the moment came and I pulled the paracord bridle, I said "sayonara Glen!" All in all, it seemed like a better way to go then watching someone being lowered into a hole in the ground, in an expensive casket.
