Talon Air’s Hawker 4000 came to Boeing Field and my shots of its arrival have already had their own post.  However, while I was reviewing the shots when I got home, something seemed a little odd between the shots.  Something seemed to be flapping around on the lower rear fuselage.  I zoomed in to the shots and there was an access panel that was unsecured.  Its angle was changing between shots, so it was clearly moving around in the airflow.  From what I can gather, this is probably where the fueling port is located.  These doors are tough, so it was probably fine, but I wonder whether any damage was done on a long flight.
