Absolutely terrible.
Though, what damage other than crashed debris in a remote land, is exactly done?
Not to support the act anyway, but as long as no one got hurt, one may not face 20 years jail time for crashing their own plane in a remote land.
Stupid? Absolutely.
Illegal? Shouldn't be.
Got it, most people in our democracy disagree with you, but feel free to vote in the next election.
Putting others in danger: should be punished.
Putting self in danger in a remote location: he can do whatever he wants with their life, even kill themselves if they want.
