Opps, I wasn't thinking in that direction, but taking that into consideration, the existing satellites that are or were in geostationary orbit have to also be considered. As of 1 January 2005, there were 1,124 objects with a cross-section of more than 1 m catalogued in the geostationary region and its immediate vicinity. Of these, only 346 are operational satellites. Two thirds of them are equipped to jet out of their current orbit upon their end of life tour but a full one third of them will remain to end with natural conclusions. That conclusion could be by contact with other objects. Hope it's not an elevator. "Look Ralph, doesn't that look like something coming awful fast towards us?" Hey, I'm full of pizza and I'm going to call it a night. Thanks for the discussion this evening.
