cockpitvisit,
Would you be interested in making that great app opensource ? It appears there are numerous people interested in such a software, some may have computing experience and could help you improve it, and make it available on other platforms (mac, linux...) !!! For example, I am currently working for a large european aircraft manufacturer on a database that would collect many information regarding airports, airlines, and routes. Your application covers an area where there is very little information available at world's scale...
Please tell me what you think,
Regards,
Guillaume
