Subject: MCC-M Response

The above is a report I have drafted on the MCC-M response to the power loss incident which delayed the Mir EVA. It starts with what I think was a recoverable error (unplugging a key attitude sensor), but inaction by the ground allows the situation to deteriorate into a major problem. It is not completely clear from the information available, but it appears the ground may have even aggravated the situation with an incorrect quaternion uplink.

A classic example of the ground having their heads "up and locked"...
