Except for the last factor, yes. Sixty Acres Park is primarily a soccer facility and was being groomed for a week-long event as we were there. It's one of the softer places one can land rockets (or bits or rockets).

My son didn't say...but it wasn't hard for him to find it. From that I'm inferring that it wasn't buried in the ground or even leaving a dent. As light as they are I don't see how one could do so on that site.
Yes, I'm thinking that the case is quite plastic in that sense immediately after firing, but when held in a motor tube you can't really see that unless you get to a just-flown model really quickly. Another that was flown without the label shows a little shrinkage of the case about 1/2 an inch down from the top of the 18mm diameter portion. I checked a couple of others - I've flown 19 of these now - and can see a little of that on some of them.

Vern has said their "test" stand back then was a small postal scale, poorly damped, which lead to such anomalies as the B16 motor, as in 16 *pounds* average thrust, which was later corrected to three pounds thrust. The B3 (predecessor to the metric B14) could floor the undamped scale by inertia, leading Vern to believe that it was indeed producing 16 pounds of thrust.
