Actually yes I did - it occured at Cheyene and Pecos and we are at Cheyene & Buffalo - about 40 blocks away and heard it and saw it
very impressive indeed - it was still burning at 1800 this evening
LOL
You get used to loud noises out here - with the test range just north
But we wondered of some one had done a nasty for a short while
the fireball went up about 7000 feet in the air - quite impressive
