Just imagine, these only had three days warning that they were coming...

I know, it's crazy. And it's scary because there is absoluteny nothing anyone could do about it if one was much bigger and was going to hit.

In which case I'd rather not know about it. Tongue

Armageddon (1998)
President: We didn't see this thing coming?
Dan: Well, our object collison budget's a million dollars. That allows us to track about 3% of the sky, and beg'n your pardon sir, but it's a big-ass sky.

When I saw the article and Hagar's post, I immediately thought of that movie (although I really don't like it Grin

I haven't seen the movie but it reminded me of the so-called four-minute warning of a nuclear attack we were promised during the Cold War. A lot of use that would have been. We used to joke that it was hardly enough time to kiss your arse goodbye. If I'm about to be blown to oblivion I would rather not know thanks all the same. Wink

And I would expect that the government would keep news of an impending collision secret. Just like most disaster movies, I would bet order and society would break down in a panic.

U.S. schools remedied that by air raid drills which immediately had children squat beneath their desks and curl up tight with their little faces as close to their butt as possible. Say goodnight and bye, bye, children.

Duck and Cover

If God intended aircraft engines to have horizontally opposed engines, Pratt and Whitney would have made them that way.

This might be cause for concern if it didn't happen every day.

Wikipedia - Near-Earth Object

Quote:

Objects with diameters of 5-10 m impact the Earth's atmosphere approximately once per year, with as much energy as the atomic bomb dropped on Hiroshima, approximately 15 kilotonnes of TNT. These ordinarily explode in the upper atmosphere, and most or all of the solids are vaporized.[26] Objects of diameters of the order of 50 meters strike the Earth approximately once every thousand years, producing explosions comparable to the one observed at Tunguska in 1908.[27] Objects with a diameter of one kilometer hit the Earth an average of twice every million year interval.[4] Large collisions with five kilometer objects happen approximately once every ten million years.

Reminds me of when I was stationed at Ellsworth AFB, SD (1982-1983), a Strategic Air Command Base with a special area for some B-52s with nukes in their bellies. When the klaxon sounded, my roommate, a B-52 mechanic, said they would taxi to the runway and after awhile would return to their parking area. If, however, should they take off, you had 30 minutes to kiss your arse goodbye.

If we spent the money building a rocket, some of those NEO's are worth $20 trillion USD or more. Sadly, NASA is great at making space boring (if you need proof, tune into NASA TV any time there's not a shuttle mission happening), so people are barely just now waking up to the economy that exists up there.

With regards to the duck and cover topic...I got this from a friend of mine when he cleaned out his parents' attic. It's amazing how the government "fibbed" to the American public at the time;

Not sure why that surprises you. Lying convincingly is what politicians do. It's all part of the job.
