Today the team have been putting the final touches to Snowbird 6 in preparation for the first sea trials on the Bering Strait tomorrow. Mark Cullum, pictured here, has successfully installed a communication system which includes a repeater station run by a generator. Mark, a member of the Hereford and Worcester Fire Brigade, has adapted swiftly to the conditions of this inhospitable environment. Mark’s main role will be helping Graham and Steve when they get out onto the ice where the real challenger will begin.
