Seems to me they have been proactive, but blowups at ILS and Sea Launch delayed all launches, and one satellite didn't make it into a useful orbit. There are two more launches on deck in the near future, E-14 and Ciel-2, and at some point the replacement for AMC-14 will go up. And I just noticed an E-15 planned for launch in 2010. Scroll to the bottom of the link and click on Echostar-15.That's not what I'm trying to say... The SAT fleet is the backbone of their operations. I'm just deeply surprised by the misfortune at Dish's feet, and it could be just a string of bad luck, but Eastern Arch, 129, 148... that's just an awful lot bad luck hitting all at once. But, couldn't some of this been avoided by being more pro-active with the fleet?
