| Entertaining and informative yes, but for one gaping hole in the presentation. Somewhere on that scale of asteroid sizes, so neatly summarized in the air above Central Park, there is a cutoff point—and I'm not sure exactly where the cutoff is—below which the big nasty rocks simply burn up harmlessly in the atmosphere. Well, except maybe for a sonic boom. [Edit: 25 meters] |
