Mission: Gora DamSoon as you start the mission base jump from the dam, open your parachute and head south above the road. Within a couple of seconds a bomb truck directly in front of you will be marked for defusal. Now do your best to spin the parachute around and line yourself up with the back of the truck, so you land on the bomb or in the very back. If you land anywhere else on the truck it's highly likely you'll be detected and the truck will stop. When you do successfully land in the back, hold
to defuse the bomb and if the truck is still moving the achievement will pop. If you do get spotted, simply restart the mission and have another crack!
