How screwed am I?

You were not kidding with flying in the mountains.

Good luck with your new bird.

Down arrow isn’t the only way to land.
If you’re in mode 2 on the controller, bring it close to the ground(8 or 10 feet) then hold the left stick down. Should land normally with that method. Unless it sees something it doesn’t like.
