Re-entry of space debris seen across UK

On the night of 21st September 2012, space debris in either the form of satellite junk or interstellar dust has been seen burning up in the atmosphere all across the UK. The phenomenon has caused a number of calls to the police regarding planes crashing.

As the debris enters the atmosphere it will have been travelling at a fast rate close to 18,000 mph, this speed when moving from the extremely low density of space into our atmosphere with an increased  air density the lower to the ground it falls. The object has much more drag upon it and therefore the friction causes it too heat up and breaks into pieces.
