14-year-old boy survived hit by a meteorite travelling at 30,000mph
and so it begins...

Gerrit Blank was walking to his school in Germany when the rock flew past, grazing his hand and leaving a smoking crater in the ground.

Gerrit was left with just a small scar. Scientists are now studying the object which is the size of a pea.

Hundreds of meteorites land on Earth every year but it's INCREDIBLY rare for anyone to be hit by one.

Most rocks heading towards the Earth burn up in the atmosphere.

The one that hit Gerrit would have been a lot larger, but it would have crumbled into pieces before hitting the ground.

Only one other person has survived a meteor strike. In 1954, a rock the size of a grapefruit crashed through the roof of a house in America.

It bounced off furniture and landed on a sleeping woman.

No.

Although a meteorite impacts the Earth's atmosphere at over 11 kilometers per second (typical 20-30 kips for Solar System objects), only the larger ones are capable of punching through the air. Anything smaller than an SUV will drop down to mere atmospheric terminal velocity; a number which is lower the smaller the object is.

I'm not sure what terminal velocity is for a pebble as is described -- I could calculate it if I spent the time -- but I'm pretty sure it's well under 200 KPH.

The description of a white cone suggests that this was not an iron or stony meteor, but something more fragile that broke up much closer to the ground, too.
