Look Up To The Sky

"Lottie Williams was struck on the shoulder by a piece of the Delta II rocket that weighed the same as a drinks can in Oklahoma in 1997. She was unharmed.
Nasa claims the chances of any person's being hit by the UARS satellite as it falls to Earth today is just 1 in 3,200. Mathematically, that means the chances of you specifically being hit are less than 1 in 21 trillion. In comparison, the chance of you being struck by lightning is 1 in 60,000.
Debris does fall to our planet from space all the time - nearly every day, in fact. Most of it ends up in the oceans that cover 75 per cent of the planet's surface.
But the UARS is the biggest Nasa craft to tumble out of control to Earth in 32 years.
In 1979 burned pieces of Skylab were predicted to land in South Africa.
Instead, they fell into the Indian Ocean and western Australia. No one was recorded as being hurt.
But as it turns out, UARS may just be a dress rehearsal. In November, German satellite telescope Rosat is expected to plummet to Earth with in far bigger chunks - including a massive lens."
