The question of what the crewman was doing was raised. Well, one of his duties at this time was to check the DECU connectors every 15 minutes. Apparently this was because of a history of the connectors working loose under the vibration. At some stage in my working life I was part of a team which probably knew as much as anyone about the technology of light duty contacts and I was horrified when that information came out. Now, we all live in an electronic age where very few of us will not have fiddled with a connection to make it work but back in the 90's not many sliding contacts, which I presume that these were, had been designed to switch an active current. You would be surprised at how much damage even a few milliamps can do to rhodium or hard gold contacts. But, for most of us, our lives do not depend on the outcome.
