Flag Tracking
Exmek, the flag in the pic of the S-62 was exactly the type used on the S-64 and S-65 when I arrived at Sikorsky in mid 1966. Needed six different colored crayons though, and when some of the blades moved around a bit, as happened when the wind was blowing and unsteady, it became a real pain in the dupa for the crewchiefs. Electronic trackers were just being tried out and the ground crews were VERY happy to 86 the flags.
Thanks,
