Two wishes on my list right now:
1. A smaller, easy-to-get around-Europe/Asia Aeronaut, and
2. A top closure for the open back pocket of the Co-Pilot. I'd prefer a full-length zipper. I've noticed that the back pocket doesn't stay flush with the bag when I'm not using the back pocket. I'd like a zipper so that I can put items in the pocket and not be concerned that they fall out either!
