My 0.02 but the airspace above the park is not the park or else you could take that to a logical extreme. A park is the land/waterways within a geographical bounds with a specific designation. It does not include the air above the park which is why planes flying over your house are not trespassing

Planes flying over your house are not trespassing because they are far enough up that they are considered to be on public highway. If you hover a helicopter over my house and hang via a rope outside my bedroom window, you are absolutely trespassing even if you have not touched the building or the ground at any point.

And going to logical extremes is always going to lead to absurdity. Let's go in the other direction. A hovercraft doesn't touch the ground, so would a reasonable person also consider that to not be on their property when it's powered on in their front yard?

How about a hovercraft, which rides on an air cushion without actually touching the ground?
