I am currently stuck in the LAX Airport mission and its while your in the elevator and it stops. After it stops I break the emergency exit in the top and climb up. From there, there are 2 cables leading up to a box that looks like cement layers. I know there is a name fore them but I'll worry about that later. I can climb on top of this "box" but that's it. I can jump from it to the next one then to a little area with power boxes. From there, there is nowhere to go. I need help.

climb up,check back a little on the concrete stantion,run and jump to the blue landing with fuse boxes,go round until you find the pipe that allows you to climb out,climb up the pipe and shimmy to you cant anymore,drop down to the next pipe move
to the right and grab the ledge pull yourself up.put your back against the wall and shimmy past the 2 pipes.
do a split jump up to the next ledge,once there across the way is a vent shoot it out,then take a running jump across.
go round the other side shoot the vent drop down and grab pipe
shimmy left and pull yourself up,go up all 3 ladders.
take the furthest of the 3 rappel points and go down into elevator exit and drop down to the next elevator.jump up to blue ledge and drop down.next part of level checkpoint.
