Wonderful job, NASA! So you send this 6.5 ton satellite up into the sky, let it hang around in the atmosphere for 20 odd years and then just let it drop back onto the earth but can't say exactly where? Then to calm our nerves they say that a satellite of this size crashes onto earth at least once a year so it is really no big deal. 

-

No big deal indeed that even after burning up most of its bulk, the largest piece of the debris might still weigh 155 kilograms. 155 kilograms! Of flaming hot metal at a blazing speed with a 1 in 3200 chance of hitting a human!

-

So much for planning life out. Plan your studies, plan your career, plan your savings, plan your future and then one random day a man made piece of junk from the depths of space might reduce all that planning to zilch or at least 160 pounds of human barbecue.

-

No, this is not a call to abandon all focus in life on realizing that at the end of the day it is so spectacularly random. This is only a reminder that there is never a guarantee on how things will turn out. All we need to do is hang on for the ride, as long as it may last.
