Hollow sounding booms followed by bright white flashes from the sky one mile south of Hillsboro airport.

Five loud, hollow sounding booms about three to five seconds apart. Each boom was followed about 1/4 second later by a bright white flash (bright enough to reflect off the wall of an adjacent building). Seemed to be coming from the sky about one mile south of the Hillsboro airport.
