Earlier tonight I think I saw and heard a meteorite become a fireball!.
Me and my 15 y/o were walking our dog when a sudden flash of blueish light lit the sky. When we looked up, we saw a streaking fire ball. It diminished with a burnout.
A good minute later, we heard/felt a boom. Very strong, but distant.
My son comes back in and determines that at the speed of sound, that noise that we heard would have had to been 20 KM away to have been associated with the flash we saw. Assuming, it was a minute between the flash and the boom.
A few more Googles and he finds this

At one minute 15 seconds between the flash and the boom it puts us dead on 25 KM.
I think that may have been the coolest I have ever seen!
It was Fn Whack!
