Jif as the hardened Canuck RSM, David Hayward as the English gentleman officer or inventor, Euan as the larrikin Aussie who's a real daredevil when driving a CMP, Max Hedges as a Carrier driver (you might need to dye your hair, Max), Bob Moseley as the lovable rogue who's making deals on the side, Jon Skagfeld as the communiucations officer, and of course we need a love interest... hmmmmm how about the RSM and the MLU Empress get it together in the end...
