How much do you think a drunk driver should get for killing a random pedestrian.
Now square that rationale with the potential to kill hundreds.
There's a difference between actually killing someone and doing something that has the potential to do that.
And to be clear :
"Punishment for a First DUI (in the US)
Generally, your first DUI charge will be considered a misdemeanor offense, and you will be punished with fines, community service, license suspension, and possible probation. However, other factors can change the level or nature of your charge resulting in enhanced sentences or penalties. For example, if you have an open container in your vehicle, you may still be charged with a misdemeanor, but your fine or mandatory jail sentence could be increased. If a child was present in the vehicle while you were driving, some states will elevate your misdemeanor charge to a felony offense, even if you have never had a prior drunk driving conviction.
In addition to the criminal nature of a DUI, every DUI has an administrative element that can be just as painful as the charge itself. For example, before you are ever convicted, some states will automatically suspend your license if you refuse to provide a breath test. This license suspension is a separate suspension from the one that comes after a DUI conviction. "
I can not stand people who drive while under the influence of alcohol or other drugs, but most people who do that are not going to jail when they're caught at all. The level of endangerment can of course increase the severity of what your punishment is, but 10 years for flying a drone near an airport is excessive. There's no reason to put someone in prison for that long, especially if no one was hurt, unless it's just out of spite.
