A widely heard loud boom during the ten o’clock hour this morning was not anything blowing up or burning down. A check of local fire emergency agencies say the boom was widely heard but nothing else was reported other than the boom.
One report indicated that three jets at high altitude were seen flying over the area immediately following the boom. When a jet crosses the threshold of the sound barrier, roughly 750 mph, it compresses gas particles on the leading edge of the aircraft and the result is a loud rumbling noise. Most modern jet fighters can reach speeds to two times the speed of sound.
It’s not customary, nor legal, to break the sound barrier over land, especially while flying over populated areas, although this writer can’t remember hearing about any jet jock getting a ticket for going over 750 in a 600 mph zone.
