   I'm not sure but I think I saw somewhere that the glitch Boeing   
   experienced is related to the heavy weather that was experienced at the   
   launch site a little earlier. So, in this case, the delay might not be   
   Boeing's fault. Nonetheless, SpaceX does seem to be a more reliable   
   launch provider.
