Getting A Ticket Via Aircraft

I'm not sure where this has to go but I'm guessing it's for speeding... maybe a lot.

On highway 7 I noticed a lot of signs that say the road is enforced via aircraft patrol.

How would the aircraft patrol hand out tickets for speeding, by mail, officer on ground, or another way?

thanks

The officer on the plane who measures your speed would contact another officer waiting on the ground who stops you and issues the ticket.
