Reward: Letter of Appreciation from Trey Research
Difficulty: Expert
Estimated Time: 35 minutes
This reward is for rescuing at least one of the three oil workers in the Oil Rig Transport mission. After you takeoff from the HQ building, follow the mission compass out to the oil rig. As you approach from the southeast, this is what you should see:
First, land on the helipad (circle 1). Just before you touchdown, you should see the first explosion. Your passenger tells you to back off, but don't listen to her. Go ahead and land anyway. While you're sitting there, she makes a few radio calls then asks if you want to attempt a resuce. Say yes (obviously), then wait a few seconds for the first victim to get in. He was waiting conveniently next to the helipad. Now would be a good time to save the mission.
You only have a limited amount of time to save the next 2 victims, so takeoff immediately. Fly directly across the rig and land on top of the high-rise (circle 2). Make sure you don't hit any railings or wires as you set it down. Once the second victim hops in, takeoff again and turn right this time (another good time to save). The third victim is on the catwalk (circle 3), and the best approach is from the north (approaching from the back in the picture). Come in slowly and be very cautious of the wires swinging from the cranes. You can't land on the catwalk, so you need to hover over the victim as close as you can. You need to almost be touching him in order for him to get in. Once he's in, give it full power and get out of there as fast as you can (once again watch out for the cranes).
Your engine will probably be smoking at this point but it won't quit. Fly back to the HQ building and land on the helipad. If you rescued all three victims you'll also receive the Netherlands Valor medal.
