Dockfighters, How to play

About Dockfighters: The Ale Wars, from BoardGameGeek:

We take you back to the year 1948, where the Second World War never happened, but the world has fallen apart. In what was Germany there are now a number of states, including Bavaria and Saxony. It is the golden age of the Planes and Zeppelins. People found it much easier to travel by air than on earth through all these splintered territories. Dockfighters comes complete with 14 magnetized aircraft and two giant airships in Dieselpunk style. Pilot experience is marked with colored rings, speed is shown by rotating discs at the hex bases and altitude is represented realistically by using magnetic height spacers. Take command of your own squadron and fly experimental aircraft nobody has ever flown before - including tiny "dockfighters" which can be "docked" on giant airships. The game comes with a Free Play competitive campaign system where each player can build their squadron through missions against any other player. You move your aircraft on a hex grid in different heights and with different speeds. Planes can be equipped with various weapons and your pilots will gather experience during each combat. Play solo or cooperate/compete with friends, in single missions or entire campaigns. -description from the designer
