Engineering Bay

The Engineering Bay is an Airside building that lets you upgrade your planes. It costs 100 AirCoins and is unlocked after a while from the beginning of the game. The building has a tip that says "the longer the flights, the better the delights!" That means you will earn more parts (see list) from better and longer planes such as the Marvel Wing.

Parts

 * Assembly Kit (can be collected from any plane)
 * Passenger planes parts (only obtained from passenger planes)
 * Cargo plane parts (only obtained from cargo planes)
 * Ramacopter parts (only obtained from ramacopters)
 * Seaplane Parts (only obtained from seaplanes and is quite rare)
