I've been to the newspaper office (same newspaper forever) and seen the original article reporting the fall, a surprizingly intelligent article, but short. The paper was a weekly published on Friday and the fall was discovered on Thursday morning. Nevertheless, they got the story into a box on the front page. I searched subsequent issues for followup stories (like "Museum Buys Meteorite" or whatever) but have not found any. Interestingly enough, local memory of the fall is very weak. The managing editor of the newspaper donated pamphlets and publications about the fall to the local library for a display some years ago, but all that material has disappeared, or to be more precise, cannot presently be located, to the annoyance of the editor (and me). Before I quit running over there for the winter, I had yet to locate the precise location of the garage. I need to do followup with the 70+ age-group. My theory of the fall is that the combination of near-verticality of path and high penetration ability indicates a high-altitude stagnation point. That is, in order to fall vertically the stone must have had its horizontal velocity reduced to a very slow speed. But to penetrate roof and car, etc. it must have been falling with a 100-300 mph speed. The object must have re-acquired some velocity in the fall. A nearly vertical fall as the original trajectory seems unlikely for several reasons. Since such a high percentage of falls are multiples, I wondered what would have happened to other stones had there been any. The area where the house and garage stood was an "addition" to the town, what we would call a subdivision today. It was created by filling a brick pit with clay and trash from a demolished brickworks in the 1920's. Had there been other stones falling with the same velocity as the car-penetrator, they would have just punctured grassy areas, burying themselves in the clay fill, leaving hardly a mark and would likely never have been noticed in the fuss over the car. The velocity is too low to produce even micro-craters and the soil fill too soft to resist penetration. My theory of a possibility, anyway... Sterling K.
