Marshalling overhead, the only thing I could think to do was reference the old 1:100 map and note my position on it, and the friendlies position. Following that, I then had to determine what the elevations were surrounding and get an idea of what the terrain was doing. Turns out it was mountainous, but with good valleys. From the current position, I then had to note time/speed/desired heading, minimum altitude I wanted to go down to (I don't know how accurate the map is), turn to the heading, hack the clock, and drop into the soup. Crosschecking time/speed/heading/altitude, I was able to eventually break out of the clouds undeneath but had to very quickly get my bearings as to where I was, where the battle was, and where the granite was. Not easy at night, with no moon and no lights anywhere besides tracers and high-order detonations. From there, was able to get the wingman to do the same thing and we were able to situate ourselves and get to work supporting the friendlies on the ground.
