Halo 3 Easter Egg - Missing Guy on Poster (the Storm)

Okay everyone knows about the missing guy`s poster on floodgate but one they don`t is the one on the storm. It`s simple in the beginning when you get out of the warthog and open the door do not open this big door yet look at the door and then look an exact 90 degree turn, and there should be a box type structure that has a light and some rope under it. Look down by the rope there.
