The Code: A declassified hostage rescue story (2015)

The pilot (Lt. Col. Hambleton) was a very keen golfer, and had played hundreds of courses and knew the direction, bends and distances to holes from memory. The O2 controller aircraft overhead would relay instructions such as "Pebble Beach 7th hole..." etc. to him and Hambleton knew the direction, range and turns he had to make to get to his next waypoint. I doubt any Viet Cong out there could second guess the radio transmissions which they could easily intercept.
Maybe it threw me off seeing the English translation of the coded message in the article: "19 people rescued. You are next. Don’t lose hope." Would have been nice if they had included the original Spanish as well!
Must confess I even had trouble copying the "19" at the beginning. Maybe that was spelled out in Spanish?

I personally really dislike when online stories lack a date of publishing.
This isn't a dupe by HN's standards because it's been well over a year since the article was discussed.
