Book excerpt: Flight of the Old Dog is one of the original and classic military techno-thrillers in the entire world. It is the basis of the PC flight simulator "Megafortress" published by Three-Sixty Pacific. It has been translated into twelve languages, and sales have exceeded a million copies. The United States and the Soviet Union are on the brink of nuclear war. At a top-secret research facility at Kavaznya, Sibera, the Soviets have developed a ground-based laser weapon capable of shooting down American satellites, and they are betting that the American president doesn't have the guts to risk starting a nuclear exchange. But at a top-secret flight test site in the Nevada desert called "Dreamland," a team of test pilots and engineers have created the Megafortress: a venerable B-52 Stratofortress strategic bombers modified with stealth technology, computers, digital avionics, state-of-the-art weaponry, and performance-enhancing features that makes it unlike any B-52 bomber--or any other warplane--ever flown. Now it's time to flight-test the Megafortress, and the Air Force assembles the best pilots, bombardiers, and navigators to see what this creation can do. One of them is Captain Patrick McLanahan, considered the best B-52 bombardier in the Air Force. The others on the crew are hard-charging pilots and world-class engineers, and McLanahan is nothing like them. But the team leader and aircraft commander, Lt. General Brad Elliott, can see that McLanahan is a quiet professional and a natural-born leader. Soviet spies soon discover the Megafortress, and they recognize that a fleet of these advanced planes can practically neutralize all of the Soviet Union's air defenses. Back-channel negotiations begin, and the U.S. is willing to mothball the Megafortress if the Soviets mothball the Kavaznya laser. That is completely unacceptable to the Soviet leader, and he hatches a daring plan to deal with the Megafortress while keeping his devastating laser weapon. Just prior to a live fire flight test, a team of Russian commandos invade Dreamland with the goal of stealing the Megafortress…or destroying it. The crew just barely manages to escape. The American president orders the top-secret aircraft back to Dreamland, but Brad Elliott and the vice president hatch a daring plan of their own: use the Megafortress to penetrate the Soviet Union's stiff air defenses and destroy the Kavaznya laser. Thus begins the aerial cat-and-mouse game across ten thousand miles and wave after wave of the Soviet Union's most advanced air defenses and fighter-interceptors, which are all on full alert. Most of the Megafortress's crew have no military training. They have supplies for only a few hours, and are outfitted for the deserts of southern Nevada, not the frigid steppes of Siberia. They have flown the Megafortress only a few times, and only in carefully scripted test flights. With Brad Elliott at the controls, Patrick McLanahan realizes that it's up to him to organize and get the rest of the crew ready for the fight of their lives.
