How close we came to extinction in 1883

Quote:A re-analysis of historical observations suggest Earth narrowly avoided an extinction event just over a hundred years ago
.
.
.

Manterola and co end their paper by spelling out just how close Earth may have come to catastrophe that day. They point out that Bonilla observed these objects for about three and a half hours over two days. This implies an average of 131 objects per hour and a total of 3275 objects in the time between observations.

Each fragment was at least as big as the one thought to have hit Tunguska. Manterola and co end with this: "So if they had collided with Earth we would have had 3275 Tunguska events in two days, probably an extinction event."

A sobering thought.

Almost only counts in horseshoes and hand grenades. I'm not sobered by it at all Smile
Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day

Glad they missed us, of course. I hope that does it for close calls for awhile.

So god saved us from an extinction caused by rocks he set in motion.
Why'd he toss 'em at us in the first place?
I suppose it's those mysterious ways again...

Because god's a "make-work" kind of micro manager, clearly. Speaking of tunguska, and so I can get some perspective on this, did they ever decide if it was impact or airburst?
I am the Infantry. I am my country’s strength in war, her deterrent in peace. I am the heart of the fight… wherever, whenever. I carry America’s faith and honor against her enemies. I am the Queen of Battle. I am what my country expects me to be, the best trained Soldier in the world. In the race for victory, I am swift, determined, and courageous, armed with a fierce will to win. Never will I fail my country’s trust. Always I fight on…through the foe, to the objective, to triumph overall. If necessary, I will fight to my death. By my steadfast courage, I have won more than 200 years of freedom. I yield not to weakness, to hunger, to cowardice, to fatigue, to superior odds, For I am mentally tough, physically strong, and morally straight. I forsake not, my country, my mission, my comrades, my sacred duty. I am relentless. I am always there, now and forever. I AM THE INFANTRY! FOLLOW ME!
