You board an aircraft with a team of adventurers to make many trips to the cities of Celestia and recover their wonderful treasures. Your journey will not be without danger but you will try to become the richest adventurer by collecting the most precious treasures! At the start of a journey all the players place their pawn in the aircraft, the players start the game with 6 (or 8 depending on the number of players) cards in hand. During each turn a player is the captain and rolls 2 to 4 dice to determine the dangers he must face (fog, lightning, killer birds or pirates). He must play cards to continue the journey and reach the next city (a compass, a surge arrester, a foghorn or even cannons). Before the captain plays the required cards, each passenger must decide whether or not to stay in the aircraft: - get off is to ensure the victory points achieved while exploring the city. - to stay is to attempt the journey to the next city to recover more precious treasures. But beware: if the captain is unable to play the right cards, it's a crash! All the passengers return empty-handed and we start a journey again with all the players on board. During their travels each explorer will be able to try to get out of the game with the help of fabulous objects (a jetpack, astronomy glasses ...) or by modifying the trip (change the route or abandon an explorer in a cited ). As soon as a player has treasures worth 50 points the game is over.
