Ok, first take a deep breath and calm down. Airspeed low is a good thing, you need to take this slowly! If the shaking of the steering wheel bugs you too much, they are adjustable, you just need to push it away from you.

Now one of the biggest dangers to planes flown randomly around the sky is other planes, so you need to get on the radio with air traffic control and request permission to crash and they can give you a clear vector from your current position to a suitable crash site.

If you're lucky, there will be a nearby deserted island, in which case surviving the crash will make a much more interesting story than a plane crashing on a deserted island and everyone dying (or maybe the island will be purgatory or something and you really did die, or maybe purgatory will be a version where you didn't crash... Be prepared to be very confused, especially since you won't get to see any of the flashbacks that gives context to everyone who will lie about everything, even stupid shit like miraculously being able to walk again or other things that would be cool to talk about).

Oh, that is unless you're one of the few adults on a plane full of kids, in which case, sorry, you're fucked.
