I could well imagine... Drone pilot flying over a site and being told to land because a helicopter is en route.
Drone pilot asks "how long until it gets here?"
It is true - I think - that most of us helicopter pilots have a much more fertile imagination than our fixed wing brethren, for whom life is mostly a beach with fast cars and faster sheilas. However regardless of my own limited imagination which precludes me even from wanting to find out what is inside dark or cloudy spaces, i am buggered if I can imagine by which medium the conversation, as highlighted above, takes place. Perhaps it is a system of semaphore smoke signals???
Happy Easter
Tet.
