A mission introduced in version 8.4.4 by Evocator. You need to head to desert airport and get inside the Nevada that is only found there.
Type /mission to start the mission if you are driving the Nevada. You will then see a red checkpoint on your map (red icon on minimap). Head to the checkpoint to start them mission.
Once you takeoff. You will have to get inside every checkpoint that comes next. Checkpoints are usually easy to enter if you know how to pilot the plane. If you finished all the air checkpoints successfully, you will be asked to land the Nevada back in desert airport to complete the mission. You must finish all the drops in less than 4 minutes or your fuel will run out and you will loose control over the Nevada. This is a hard mission and gives you alot of rewards once complete. Good luck!
