As far as my challenge, I think your vague reference to "reference papers and project management documents" doesn't cut the mustard. Because I'm a nice guy, I'm going to make the donation anyway. Do you expect us to believe you had read these documents then assumed since it had been eleven years the satellite would be turned off while in eclipse? You got me! I have paid you a compliment. I've agreed with you before, too. Don't tell Santa Claus -- I've been bad this year, too.
