"Frank wants you to steal a plane"
in your first mission back out and free, and Frank is now bossing you around. He wants you to steal a plane from Dr. Paul Severn. Frank let him win an auction for a seaplane but Frank actually really wants it, so we need to head to the Marina and steal it.
Once you're at the Marina, you need to head down onto the docks and deal with the few guards protecting it. There isn't any cover down here so you'll have to use brute force against the enemies. get in the plane once you've cleared the area.
you can change the flight Controls, as with driving, though these are easier to use motion controls with. Once in the plane, you need to fly to the marked location and 'park' the plane on the dock. Landing on the sea is actually really easy, just circle around so that you're coming in from a better direction to stop on the objective marker. Once you've done that, you're mission is complete.
Reward: G120,000, Respect: 490,000
Note: Complete this mission and you unlock all of the air-related diversions, including Aerial Racing, Ring Challenge and new Time Attack missions.
I haven 't play the games yet but I think why don't just drive a boat and get on the plane
