Actually the first time I played the mission I beat it.
However, for some reason I didn't save it.
Good thing I didn't save it because I got to keep the hovercraft and the go kart.
They are both parked at the beach save house near the mission.
It's really not that hard...
I haven't tried it again.
I kinda don't want to beat the mission..
There are only like 5 or 6 missions left before you beat the game..
