The way I interpreted NASAs comment is there must be a slight possibility
of landing in a crowd. The 1:1000 is the mathematical expectation
of one in a million chance of smashing a thousand proles is the
same as 1:1000? I agree tho, 1:1000 sounds pessimistic. Oh
well, we will build them another one. {8-]

Before you go too far down this road, do the calculations on how
much delta vee it takes to deorbit a satellite. Then calc how much
delta vee it takes to change orbit planes (its a lot). spike
