Mythbusters tested the sonic boom myth. An F/A-18 flew ridiculously low (200 ft AGL) before the window cracked with a supersonic flyby. A sonic boom from a fighter jet above around 10,000 ft usually doesn't break any windows. In one case, a General flew a F-22 in supercruise just off the Florida coast at over 50,000 ft and nobody "reported" the boom until the media story ended up on the news. For low level supersonic flight, what typically happens is the pressure wave created either overflexes the window pane, or the window frame isn't strong enough and the glass falls out. For a larger aircraft like the Concorde flying above 40,000 ft they wont break windows. People complain about the noise.
