FSX SR-71A Blackbird. This is my 3rd update for FS X of the Alphasim SR-71A Blackbird. This update is ONLY for those with the Acceleration pack, and possibly for those with just one or both of the updates. If you have either of my previous updates and it now flys too slow, this update is for you. I have redone the panel adding switches and a fuel gauge in place of the clock, and changed the autopilot, I have changed the afterburner effects, and updated the flight dynamics so you can cruise at mach 3 or more.
