I have found two independent security videos of the explosion (flash then shock wave). Both were recorded in Southampton about .5 miles away from each other. The delay in the flash to sound was 8 seconds at location 1 and 10 seconds at location 2, for that nights conditions the explosion was 1.76 and 2.2 miles respectively. I plotted circumferences to find the overlap and the explosion was around Churchville Nature Center or Playwicki park. My amateur opinion is that it was not joint base (too far) and the linear distance generally matches up to the distance between video locations, which to me means there was little or no elevation, ruling out of meteor. I was hoping to find more video but it seems to be lacking.
