You fly over North America, the Indian Ocean, and Asia on missions. Thunderbirds fly five futuristic aircraft, including the Mach 20 Thunderbird 1 Rocket, the Neptune Hydro-Turbojet, and the Fire Flash Atomic plane. Each vehicle is grounded after three impacts. Repairing a grounded car takes 3 days. These 3 days will be deducted from your 60-day game completion time.
