This is really a question for an elderly ATCO: any old ATCOs out there remember?
I'm not an ATCO, but to the best of my recollection, back in the 1950s this used to be a procedure for aircraft with radio failure while above cloud. I seem to remember that different meanings were ascribed to the direction in which the triangles were flown, but I can't remember what that was. Basically, the idea was that the radar controllers would spot the blip flying triangles and despatch another aircraft to intercept and escort the lost aircraft to safety.
That's all I can remember, anyway.
