And then if you look even further down the road

and your consumer drones are out there and Amazon's flying

its drones and Facebook's doing its project and whoever

else is trying to compete with Amazon so then we've

got all these drones in the air,

what about these things hitting each other and how do you

deal with that, do you need technology to allow these

things to fly, say.

Several companies are taking that on,

NASA's got a project taking that on,

the FAA's looking at it,

I believe all the planes in the US, even the small ones

will be required to have what they call ADSB technology

which gives a GPS signal and receives it on the frequency

bands and that technology could be used in the drones

as well and that will keep us pretty safe apart,

the part we haven't solved yet is to make absolutely

sure you're not going to hit a tree.
