I don’t think you need to obtain permission from anyone to fly.
Parking is on Snake Road (Snake Pass Summit) on the A57.
It’s a few miles to the crash site and weather can change so be prepared.
It can be a bit treacherous under foot to reach the site.
NOTE - I made a mistake with the take off and landing location.
We took off and landed at the crash site itself.
