Do you pay royalties to the likes of Airbus, Boeing, etc to use their names? I'm just curious how that works...
The names (airports, aircraft) are displayed/used only for illustrational purposes, and fall into 'fair use' category, so taking it that far is not really necessary.
(have to add though: the a/c images are of course used with permission or are public domain, I meant the display of planes in the images etc.)
