I remember the WWII Fighters from JANE'S.
Hey, i was 9 or 10, i think, when i got this, but hey, it kicked ****ing asses for me.
On every plane in the sim, there was a gallery with like guns, engine etc. on the aircraft and about 5 to 10 mins of voice recording telling you all you need to know about,for example, the engine of the plane.
Hell, i felt fantastic flying this and had a shitload of fun.
