Just a word to all you professionals out there,next time you spot a spotter.
Years ago I was once standing alone at the crash gate at the 23 end at GLA on a cold winter's day when a taxying AA DC-10 came along and stopped right in front of me.
Armed with my camera I zoomed in to the cockpit windows and saw the pilots give me a wave. It made my day.
Seem to recall it was mostly USA pilots who obliged in this way.
