The Russians say that there is a 2% chance that space station MIR will land on Australia. They also predict that it will "touchdown" between March 15th and March 22nd--somewhere in the South Pacific. My question is: should I be scared? [Note: I did have nightmares about SkyLab back in the 1970s--luckily that did not land on my summer camp in Northern New Hampshire; but it did land in Australia].
