Russian Unmanned Rocket Explodes Moments After Launch
If Russia was hoping to punctuate its foreign policy victory over the US in hosting Edward Snowden and being on the list of his asylum applicants with the overnight launch of a unmanned Proton-M rocket, carrying some $200 million worth of navigation satellites, those hopes literally went up in flames when 17 seconds into the take off, an emergency switch-off of the engines led to a spectacular explosion, and sent the rocket plummeting to earth.
