Bomb the debris
A very large floating dock just washed up on the Oregon Coast. Where was the U.S. Coast Guard and other government ships and planes? Did no one see this arriving?
Since the tsunami debris field is so huge and there will be other giant pieces coming in, why can’t the Navy or Air Force planes in the region go out and bomb and strafe this mess? It might break it up enough to make it sink really deep in the ocean instead of being a hazard to shipping and eventually beaches in the west.
