I slammed his ass with the banstick about 3 seconds after I figured out what the bastard was doing. Then, I regretted doing so as I wouldn't be able to spec him entering the building.
It would have been ideal to slay him and then watch him re-enter the hanger "basement" area. Nonetheless, with a little Internet research, I have figured out how to enter these areas, and this exploit is not limited to el alamein...
