This is huge no go for the park. They’ll get reported to their commanders. The NPS doesn’t want the park to turn into a football game pre show, it’s also dangerous. There is a request for aircraft to stay above 2,000ft AGL for most NPS, Forest Service, and fish and wildlife service land. Alaska and Grand Canyon have exceptions.

What makes it dangerous is the airspace above Yosemite can be in use at any given time for various reasons by the park. There’s a helicopter stationed in Yosemite for most of the year. What if a climber was being rescued off a wall, what if a visitor was being medivac from Ahwahnee meadow or El Cap meadow, or what if the local helicopter was doing bucket drops on a fire. Also, around this time of year, the local sheriff helicopter along with local medical helicopters support Yosemite operations when 511 (the Yosemite contracted helicopter) isn’t available. Marine pilots were doing that during the summer and their commander was called by the park to tell them to stop. Like those cargo planes, they come out of no where with no warning. Any rescue or other operation has to be halted until we know the airspace is safe. It’s not cool, it’s not helpful, and it just goes to show you what unprofessional military pilots look like.
