First of all, we all owe Dave a big "thank you" for the existence of this site.  Also, all of the people who volunteer
            their time and effort to supply the feeds.  If it weren't for them, you wouldn't be able to listen to atc from hundreds
            of airports all around the world.  Secondly, the app doesn't cost much more than a cup of coffee at Starbucks. I think
            that's a pretty good deal - it's the best $3 I've ever spent.  Finally, this whole thing is a labor of love - by and for
            aviation enthusiasts.     So........    thank you, Dave
