I would tend to agree that there is not much for the maint dept and the line pilots, more slanted towards the upper management types who buy the aircraft and all the other toys.
I had a lot of people come by the booth giving us some good feedback on my magazine, with many saying its good that someone looks at the industry from an operators standpoint as we are trying to do with Pacific Rotors.
Hopefully next year HAI might start catering it a little more towards the line pilot, since they make up the bulk of the attendees.
