I thought about it, but I can't seem to remember how the controls work for the harrier...
All I know that it is the vertical plane right? It had something to do with throttle with your right analog stick and steer with your left. As soon as you're in the air it's only steering and you can leave the throttle alone and just fire away your sidewinders. Like I said maybe this doesn't make sense at all, but that is what I remember. Sorry for not replying earlier, but I thought that someone who had a better memory should help you out.
