The day at XM655 started fairly dry with a glorious sunrise, but as the day progressed it became increasingly soggy.

Despite the wintry gloom, we were able to get on with quite a lot of jobs, including refuelling the aircraft to move the cg forward in case of winter snow, replacing an empty nitrogen cylinder, fixing an electrical problem in the cockpit lighting circuit and fitting a new tyre to the Sentinel tug.
