Quantico, Va. — What do you get when you mix a 500-pound bomb and just the right weather conditions? A big boom that was felt across the Potomac Communities on Thursday.
Marines on Quantico’s munitions range detonated a 500 – pound explosive device about 2:30 p.m. While there have been larger bombs detonated at the range before, officials say low-hanging clouds helped to compound the effects heard and felt by this particular explosive.
