And I think that is the problem.  Nothing we can use legally in the U.S. is 
going to go those distances.

Laser need LOS in the real sense. Fog, rain, smoke, birds, planes, ...
Or you give them enough power to remove the problem ;-).

Ah, I guess my subconscious desire added that.  I have always thought that 
lasers backed by RF would be the future of wireless.  They'll have to have RF 
also for when a bird flies through it.

I don’t see the “on the ground” part:

We've also made a breakthrough in laser communications technology. We've 
successfully tested a new laser that can transmit data at 10 gigabits per 
second. That's ten times faster than any previous system, and it can accurately 
connect with a point the size of a dime from more than 10 miles away.

It talks about the lasers being able to align to a spot on the ground "the size 
of a dime".  That seems like drone to ground lasers to me.

Lasers between drones, RF to ground.

Still probably more challenging in the real world than Facebook is 
anticipating.  But they also are probably not designing for people who will 
complain to the FCC about not getting 99.999% reliability.

The interesting part is the laser working at 10Gbps at 10 miles.
