Yeah it sounds like the geography is a lot smaller. The four Networks, ABC, NBC and CBS along with fox do share helicopters but it's not unusual for them to be in Reading Pennsylvania and then get an assignment to go to the far south end of New Jersey for wildfires or something or some shore event then fuel up.. after that they're going to a murder shooting scene in Center City Philadelphia which happens several times if not much more, every day.
Philadelphia rivals Chicago with violent crime and murder, police often restrict the Choppers to a certain perimeter and definitely don't allow drones anywhere near the airspace of their police helicopters.
I guess it has to do with size and geography, the four network stations cover a very wide area they broadcast too.
Thanks for the reply.
