THE BALL!
I took a picture of the "ball" so everyone can see how Erik lands the plane on the boat. This is what "the ball" looks like on the boat. Apparently, when Erik comes in for a landing, the ball is supposed to show him where to position the plane so that he will successfully land on the boat deck. The ball is actually a light that would show up to a pilot in that center black thing. If the pilot sees the ball above those green lights he is coming in too high. If its below those green lights he is coming in too low...Now, that is all I know about that one!
