Seems strange that the other diver is following the same path as the meteorite and passes by just a few seconds later. Could he have dropped it and it accelerated to a speed faster than he was travelling?

Re: Norwegian skydiver nearly struck by meteorite
#42JFYI To be hit by a meteorite you would either need to be close to the Earth's surface or for somebody strong to throw it. Technically it is not a meteorite until it impacts with the Earth's surface, therefore this object may actually be a meteoroid.
> Technically it is not a meteorite until it impacts with the Earth's surface, therefore this object may actually be a meteoroid. Not quite. Before entering Earth's atmosphere, it's a meteoroid. While passing through the atmosphere, it's a meteor. After landing, it's a meteorite. http://www.livescience.com/27183-asteroid-meteorite-meteor-m...

#43April Fool?
Any Nordic types following this story?

Meteor is a description of the burning in the atmosphere not the object itself, which is still a meteoroid.
Yes, fair enough. Unless the object is consumed in the process of generating the visible presentation (often true), which makes it a meteor -- or perhaps I should say "turns it into a meteor".

#46But still, the odds of a strike on _an_ aircraft over the next 20 years are about 4%:

at any given time, airliners cover 2 billionths of the Earth's surface. There are 125 meteors an hour, each with probability 2x10-9 of striking some airplane. In 20 years, that's about 22 million independent possible impact events. The chance that every one of those meteors misses every airplane is: ppois(0,2e-922e6)*
(Using R).
So the odds of an asteroid flying past a skydiver aren't as infinitesimal as one might otherwise think.
It also makes one wonder at the possibility of space-junk collisions being the cause of past aviation accidents. There's little enough evidence this would leave, particularly for a flight which disappeared entirely without a trace, or whose wreckage was only found much later.

#47My guess: a rock that fell off the undercarriage panel of an airliner, and was carried by strong winds. Or a particularly slow meteorite.

ie, thrown it? That does seem far more likely than it being from space.
Re: Norwegian skydiver nearly struck by meteorite
#49Isn't it more likely that the rock fell out of their plane?
