Until we get our flying cars, one way to take advantage of all of that unused airspace above our heads might be to build a bunch of tiny 'pocket airports' in local parks and fill them with futuristic flying SUVs.
Birds and airports don't mix. I mean, yes, both are based around taking to the skies, but birds have a pesky way of splattering on windshields and getting sucked into jet engines that can cause a serious number of problems....
