I'm going to jump in here. I'm a libertarian and an American. This guy absolutely should have his license revoked for his lifetime.
We have an interesting legal structure where I own a piece of property, but my ownership only extends so far vertically. I cannot stop a plane from flying over my house.
But the other side is that folks who fly planes are given great responsibility because they're flying something that can cause a lot of damage on the ground.
Now, I know he was out over the middle of nowhere when he abandoned his plane and he purposely did it out there to minimize the chance of harming someone. But "minimizing" and "eliminating" are two different concepts, and what he did had the possibility to cause great damage or death to someone on the ground.
And he did it solely to get attention online.
So, no, he should never fly again.
