Was at the ocean beach pier in san diego. we heard two really quick loud booms one after another. a large gust of wind hit us and the ground shook. it was reported by many people all over san diego, from the beach into santee and by the mexico boarder. the media looked into possible sonic booms, any military air crafts, any bombing off shore and earthquakes. they found nothing to explain this. so we wonder if it could have been something not of this earth?
