What is theirs?

The operators probably have to eyeball the airspace over the
160 acres being photographed. The mission is to take
photographs of fields, so it will always take place in relatively
clear conditions.

They ought to be able to see full-scale aircraft entering the
airspace and command the UAV to descend or change
course to avoid the traffic.

They might also be able to monitor air-traffic channels
and get the controllers to warn them of approaching
traffic.

I'm sure that the UAV is not cheap. The operators will not
want to have mid-airs any more than other pilots.
