Wings of Power is a set of two flight simulation video games released as add-ons to Microsoft Flight Simulator 2004. They add vintage historical military aircraft to the game. Wings of Power: WWII Heavy Bombers and Jets was released in 2004, and adds 50 missions with some historical missions from real military pilot logs from World War II. Wings of Power II: WWII Fighters, was released on June 27, 2006. It adds five aircraft: Bf 109, P-51 Mustang, Spitfire, P-47 Thunderbolt, and A6M "Zero". The aircraft in Wings of Power: WWII Heavy Bombers and Jets include the B-17 Flying Fortress models F and G, B-29 model a Superfortress, Arado 234B Blitz, He-162 Salamander, Focke-Wulf Ta-183 Huckebein, Avro Lancaster Mk III heavy bomber, B-24 models D and J Liberator and PB4Y-2 Privateer. This add on is strictly with pilot or copilot controls only. So there is no combat in this add on unlike Shockwave's earlier Firepower add on. However the developers added some sophisticated controls and actual pilots procedures used to start and fly these aircraft in the simulation. So they simulate how the aircraft is actually flown to a very good degree. The simulation add on comes with a good size 158 page manual detailing the controls and operable 2D panels which can be brought up on the computers screen to manually operate different control panel boxes used in the actual aircraft. However, not all the actual pilot and copilot controls of the real military aircraft are here in the simulation most notably the B-17's induction system. Unfortunately this is due to a limitation of Microsoft's Flight Simulator 2004. Even so, this add on would be useful for learning some of the operation and procedures of the actual World War II military aircraft. The simulation is designed so that the aircraft operate and fly to pretty decent flight dynamics as the real aircraft. So it can be a challenge to land a heavy World War II bomber in the simulation without crashing and there can be random failures of aircraft systems so a simulation pilot can learn what to do in certain circumstances.
