Today is the deadline to register your drone with FAA

If you have a drone and you haven't registered it with the Federal Aviation Administration -- today's the last day to do it or you could face fines.

Friday, Feb. 19 is the day the FAA says federal law requires owners of drones weighing between 0.55 lbs and 55 lbs that are flown outdoors to register them.

Registration costs $5 and is valid for three years.

There is a caveat: Those who bought their drones after Dec. 21, 2015 have a deadline that simply requires they register before they operate outdoors.

The FAA says more than 342,000 people have registered their drones. That's more drones registered than the number of registered manned aircraft.

What happens if you don't register your drone? If you are caught, the FAA says you could face a civil penalty of up to $27,500, a criminal fine of up to $250,000 and imprisonment for up to three years.
