A few tipsters have just alerted us to some "loud-ass explosions near Battery Park City," wondering, "What is are those loud booms downtown??" These explosions were planned, and as NY Aviation points out, "it's the NYPD blowing up 'damaged munitions' on Ellis Island." The explosions were scheduled to start at 3:15 and last 30, so they should be all wrapped up now... but we swear we just heard one a second ago!
