Unofficial Russian sources say that the May 16th failure of a Proton-Briz M rocket carrying Mexico’s Centenario / Mexsat satellite was caused by “human error”.
The formal Investigation Board report has yet to be issued, but Russian news agency TASS states that a “number of violations” have emerged during the investigation. “This is, undoubtedly, a human error. The fault occurred in the rocket manufacturing process,” said the TASS source.
The investigation commission is due to report on May 29th.
