All 3 of the big commercial sat launch providers (Baikonur, Sea Launch, and Guiana) have a failure rate of about 11%. As "routine" as satellite launches may seem today, the truth is that it is still a very risky adventure.
Exactly what I was pointing out. Everyone on this board acts like D12 is a sure thing. Heck, shortly after the AMC-14 failure, I remember seeing some accusing Dish of using an inferior provider to DirecTV, which just launched D11 on Sea Launch. Little did they know a few DirecTV sats have gone up on a Proton.
