I live downtown and I work till the wee hours of the morning as most of us do. EVERY night I hear the loudest bangs and explosion sounds. But I never see anything - sometimes it sounds like a cruise ship has smashed into the dock or someone dropped a dumptruck off a high building. Very odd stuff. Sometimes I think it may be coming from the container ships and the cranes that lift containers - but they don't work at 2am.
