As you can read, the threat is being taken seriously. I'd love to be looking over the shoulder of the White House scribe who is drafting the message for the president to read. It would be the "mother of all warnings." Everyone should "bend over and ..... goodbye!"
For those of you too young to remember Deep Impact, the movie, it provides a skewed glimpse into what it might be like. Not knowing the details, and in this case "size matters" when it comes to Near Earth Objects (NEO), I'm thinking it will be like a really, really, really big thermonuclear explosion. A tsunami of major proportions if it hits an ocean and a humongous dust cloud if it impacts land.
As any old-timer will tell you — at any disaster scene today, "I've lived here all my life and never seen anything like this before!"
