I didn't see any fireball. Just a large explosion... A black cloud with lots of brown dust mixed in, shooting 3-400 feet into the air... Mostly straight up with one very large piece flying off to the south-southwest followed quickly by a loud BOOM (I was about 1/2 mile away at the time so the sound and pressure wave were a bit delayed) but it most certainly was a "detonation".
