File Description: FS2004 Flight Plan for OB-20 Holbrook Arizona IFR high speed low altitude military training route. This is the eighth in a series of FS2004 flight plans I have uploaded. This route goes through mostly flat and rolling terrain in Colorado, Utah, And Arizona. These are great routes for B-52, F-111, B-1B, B-2 A6, A4, Vulcan and any fighter or bomber enthusiasts. Of course you can fly the route with any aircraft of your choice. Included in this package is a gauge by Karol Chlebowski for TFR flying at very low altitude. This gauge will greatly enhance your ability to fly these challenging routes and is a great companion of the flight plans. Another option to download Version 2.0 of my FS2004 mini panel which has all this functionality and more.
