(operations room chatter)
-: The Royal Observer Corps
would transmit to the Operations Room.
And we would pick up the coordinates,
put down your marker where the map reference is.
You had a stand and you put on the stand
the number that had been given.
That particular aircraft, or wing, or squadron.
Then it would be how many were in it.
And then it would be the height they were flying at.
The hour was divided into red, yellow, and blue sections.
And according to what the color was on the clock
that colored arrow you used.
So that the officer, who was controlling the aircraft,
could see from that when the aircraft took off,
how long they'd been in the air,
and which direction they were going in.
