- carpespasm, on 01/01/2008, -7/+189why is it called a near-miss? it was a near-collision.
- badassninja, on 01/01/2008, -8/+109No, that was clearly Goku flying as fast as he could to save the world. Head line should have read, "Goku, how the planet was nearly exploded."
- uferme, on 01/01/2008, -4/+56Amazing video, especially for 1972. You have to be fast to get a shot like that.
- rasalibre4life, on 01/01/2008, -0/+42This is actually what the meteor from "Armageddon" would have done. There really was no need to drill through it and blow it up. Bruce Willis died for nothing.
- nasalspray, on 01/01/2008, -1/+41Yes. You're quite correct in asking and answering the same question that George Carlin did in 1992.
http://us.imdb.com/title/tt0246643/quotes - badassninja, on 01/01/2008, -3/+31You are correct sir.
- drizzlelicious, on 01/01/2008, -3/+29Right around Midgar.
- Humptydank, on 01/01/2008, -0/+24Nothing really. Sparks, those little whistles you hear at fireworks shows, oohs and aahs and clapping. The usual stuff.
Oh wait, and Alberta would be turned into a sheet of glass. Forgot that part. - rocknroll4ever, on 01/01/2008, -1/+24 Hey im from Canada ! How did it get through customs without being checked out first ?
- Furkle, on 01/01/2008, -1/+23They reserve special spots in hell for people like you -.-
- Bob042, on 01/01/2008, -4/+26It's called a near miss because it was very near, but still a miss.
- lhbaker, on 01/01/2008, -3/+25I wonder where the meteor would have struck had it deflected downward instead?
- Dysarthria, on 01/01/2008, -0/+21Amazing because it's not video at all, but film, and that someone had the foresight to preserve it. Those home movie cameras were nifty - but were dumped when camcorders came out. The had no sound, no zoom, expensive film, and required a projector/ screen. A lot of these cold-war era "home movies" are rotting away in their canisters; but some are the only records we have of important events (this meteor nearly striking earth, JFK getting assassinated).
- weezcnr, on 01/01/2008, -1/+20Good old flying nimbus.
- sexualaj, on 01/01/2008, -1/+19Holy *****!!!
- sjbdallas, on 01/01/2008, -2/+20Somewhere in canada it sounds like.
- iDiggIt42, on 01/01/2008, -2/+20Rick Roll alert for all of those who do not already avoid things ending in uuiU.
- LBobRife, on 01/01/2008, -0/+16Try throwing a stone across water. You will find that depending on angle of entry and speed, the stone either deflects up or hits the water and sinks under it. I assume a meteor against the atmosphere works in somewhat the same way, except the atmosphere would be easier to pass through than water.
- Alex2, on 01/01/2008, -0/+15Hiroshima ~ 13 kilotons (from wikipedia)
Assuming an iron meteor, 10 kilometers per second, 5 degree angle, 5 meter diameter meteor, the calculator only gives 5 kilotons.
I'ts only half a hiroshima in blast size.

- sjbdallas, on 01/01/2008, -4/+19I'd be interested to know whether NASA was tracking this or predicted it to hit.
- inactive, on 01/01/2008, -1/+15IT´S A TRAP !
- Treshnell, on 01/01/2008, -3/+17The atmosphere.
- thailand1972, on 01/01/2008, -0/+14Because he can't talk
- kindrobot, on 01/01/2008, -0/+13I had 2 reels of Johnny Cash performing before he was famous that my dad shot on 8mm. One reel is all that's left and the other was mostly liquid when I found it. Check your garages , folks.
- Virgule, on 01/01/2008, -0/+13same goes for "lost objects" boxes instead of "found objects". :)
- Scynet, on 01/01/2008, -0/+12Of course, the density between space and the atmosphere is like that between air and water. Hit it with too big angle and you'll skip like a stone. However, if you hit it too straight the friction will burn your ass, so re-entering is always careful business.
- ChileanGoD, on 01/01/2008, -1/+13Tetons.. hahaha... That's one way to say "*****" in french (at least in Quebec) :).
- themastersb, on 01/01/2008, -0/+12I's not luck. It's skill.
- plato1123, on 01/01/2008, -0/+12they had it coming though
- Zaphrod, on 01/01/2008, -0/+11According to Marco Langbroek of the Dutch Meteor Society citing Z. Ceplecha, even if it had the correct trajectory to hit instead of miss it would not even have created an impact crater as most stated masses for this meteor are "grossly overestimated".
He Writes,
According to Ceplecha (Astron. Astroph. 283 (1994), 287-288)the oft quoted
masses for the 1972 grazer are grossly overestimated. From his dynamical
studies on the fireball he finds an initial mass in the order of 40 metric tons
(much lower than the earlier estimates), of which less than one third had
survived at the 53 km perigee. A 40 metric tons mass equals a body about 3 to 5
meters large, depending on which density you take.
According to the study by Hills and Goda (Astron. J. 105 (1993), 1114-1144),
such a mass with the entry velocity of 15 km/s actually is in the regime where
(assuming it is stony) it would severaly fragment due to dynamical stress when
descending lower in the atmosphere. Depending a bit on wether it was a soft
stone (carbonaceous, as Ceplecha finds most likely from the dynamic behaviour),
or hard stone (ordinary chondrite/achondrite), the largest surviving fragments
that reach earth surface would be only 0.002-0.003 kg (soft stone) to 0.5 kg
(hard stone), so actually very modest compared to the typical meteorite from
smaller original body sizes! At these sizes, they will quickly decelerate and
hit earth surface with the typical subsonic speeds for a normal meteorite,
hence no craters but relatively small impact pits at best. Yet, there would be
many of these, so it would result in a spectacular shower and strewnfield
formation of relatively small meteorite fragments - but litterally thousands of
them. Something like the famous Pultusk, Holbrook or Homestead meteorite
showers.

- Treshnell, on 01/01/2008, -0/+11Hiroshima, take 2.
- spyofchaos, on 01/01/2008, -0/+11I think this week I broke my record for being rickrolled' ... Seriously it's getting old. Can't believe I got rickrolled twice in this article.
- Treshnell, on 01/01/2008, -1/+10That's an amazing shot, once in a lifetime catch.
- PRlME, on 01/01/2008, -2/+11if your trying to start a trend with the Ron Paul thing, as a fellow Ron Paul supporter can you please not do that.
- norcalscan, on 01/01/2008, -0/+9Bruce Willis dies? Dammit! Way to spoil it.
- BrownBoognish, on 01/01/2008, -1/+10Sniffed that out a mile away bitch. Try harder next time.

But perhaps not. - DiggMasterJ, on 01/01/2008, -0/+8Around heres we call those "lost and found".
- r3becca, on 01/01/2008, -0/+8I disagree. Since lhbaker was pondering a hypothetical situation there are at least a couple of variables that if different could possibly have resulted in the meteor not leaving earth's atmosphere:
The meteor having a slightly different trajectory.
The meteor having a different density. (ie: lower density would be slowed more by atmospheric drag)
The upper atmosphere having a different density (it is not constant).
The meteor breaking up. (would increase surface area and thus drag) - Wacer, on 01/01/2008, -0/+7I saw a documentary that stated the government was caught off guard. Then again, they didn't even have money funded to look for this stuff back then.
- Culero, on 01/01/2008, -0/+7@ nasalspray
it's ALSO possible that more than one person can have the same thought....I'm sure at least a few people thought the same thing even BEFORE George Carlin....*GASP* - Perk, on 01/01/2008, -1/+8They were named by a lonely French fur trapper... you figure it out.
- Petraios, on 01/01/2008, -0/+7Near miss has a long established definition of being an almost hit. It was near, but it missed.
- inactive, on 01/01/2008, -8/+15It´s the Burning Legion.
- BryanJK, on 01/01/2008, -0/+7I've been rickroll'd about 5 times today all on digg :(
