I guess that this shows that we still have a lot to learn about upper-atmosphere meteoric explosions -- were any hard data on radiative vs blast energy collected from previous similarly-sized events?
I would guess that military observation sats have recorded similar explosions in the past, but their detailed results would presumably not have been made publicly available. I would love to see a plot of total energy vs blast/radiation ratio vs detonation altitude for as many events as the information has been obtained for. |

So we have a military high-atmosphere monitoring system? Relic from ancient "Star Wars project"? Do those acronyms in that page mean that there are so MANY USAF satellites up there? Or do they refer to observation times? |
