I'm not sure coz I'm not very good with this stuff but
you know the LST? It has a helipad on the back end, and when I tried landing on it, the ship went flying forward, as if it had a warp drive or st! lol. It went right up the beach!
Same thing happens if yoy nudge it with a PBR mk II.
My point is that maybe it wouldn't work because of this screwed up version of Newton's Xth law.
Maybe if you could make a separate island in the form of a carrier so it wasn't actually a unit and you just made an intro and outro with it....
hope that helped,
Chris
