BBC News - Nasa refines satellite crash time (http://www.bbc.co.uk/news/science-environment-15021323)

I know it will be a needle in a haystack but I was wondering if there will be any effect to Air Traffic!

From my sources (as at 16:00 GMT) it seems Northern Italy is a contender.:sad:

Presume the pieces left after entry would be tiny?

Odds are against it, but talk about dumb luck if it happen to hit something airborne.

NASA estimate that there will about 500KG of the satellite which makes it to earth and they think that this will be in about 26 pieces, the largest of which will be over 150KG.

The largest chunk of wreckage from UARS is expected to be about 331 pounds (151kg), says Nicholas Johnson, chief scientist of NASA's Orbital Debris Program office at the Johnson Space Center in Houston.

Velocity of 4.5 miles per second, that could be a very big bang from just one piece of debris.:eek:

How does this man-made projectile compare with meteorites?

If the pieces do hit an airliner, sue the pants off NASA....there gonna be some very rich widows and widowers.

Not just NASA would get sued but also the country it comes down in.The closer it gets to re-entry time the better NASA will be able to define its crash site. Wouldn't take too much for a government to close its own airspace for the duration then later sue NASA for lost ATC revenue.

Northern Italy! Any chance a piece would catch Berlesconi with his pants down? Bunga, Bunga, indeed.

Lon,

I very much doubt NASA (or the US Government) would pay up.
