Here's my latest aircraft on a coin, an airbus A380, the pride of the Airbus fleet. In the other fields you can see a Concorde, a Zeppelin, a helicopter, the ISS, a balloon, Lilienthal's glider. I believe the balloon is the Montgolfier and the helicopter may be a Sikorski S 55. The bat wing left below could be a reference to Icarus.
