I was an active WB pilot when HT and Pyro were bought out by iEN. That was way back in 1998? I'm not sure. Maybe earlier than that. Besides the fact that the community entered a general state of panic, there was a noticeable change in how the product was developed and managed. You really got the feeling that the new ownership did not appreciate that it had bought a high-fidelity flight simulator, and instead viewed the product as mere entertainment like other computer games. Wildbill was laughable in his attempts to convince the player-base that he cared about the same things they did, and that he understood force-based flight models just as well as HT. It is a long, sad story.
Ironically, one thing that really seemed to drive people away from WB was something I really liked: the rolling plane set. The whining and wailing was insufferable. Consequently, AH suffers from the same defect as the original WB: the utter lack of use of its mid-war and early-war aircraft.
