> You wouldn't be trying to give a ticket to planes flying overhead except you have just applied an assumption (which is often true) that may not be true depending on circumstances - that the planes were excluded because it couldn't have caused any negative effect. For example, if the park had been https://en.wikipedia.org/wiki/Sentinelese#Isolation_and_uncontacted_status https://en.wikipedia.org/wiki/Sentinelese#Isolation_and_unco... , and the intention was to keep the indigenous peoples isolated. But this isn't a part of the rule, and it is an interpretation of the rule by the administrator. A different administrator might interpret planes that fly higher than audible altitude would be OK, while another one might consider a visual detection altitude to be a violation. And another might consider no altitude to be permissible (because if they crashed right there, they'd be falling into the park).
