Seconding Claude's ask, can you draw an approximate line on a map from the launch pad out in the general direction you saw it come down? Google maps image of Woodsom Farm has a ring on it from the general launchpad setups at CMASS launches to use as the starting point. I used this method (and a pile of luck) to find my Estes Astrocam that fell off my last flight in November this past weekend. That's much smaller and more camouflaged thank your Volcanite should be.
It flew on a G80-7t from the low power flight line toward the road and dwellings. If you were standing at the safety inspection rocket check in, it would have been slightly toward the right. It may have gone across the road or into a yard. i don't know. I had it insight and then I lost it in the sun. This was at about 1:50pm. thank you!
