So I just read the other thread about the K language[1] and how it's so-very-concise syntax made the author feel certain ways.
But that has nothing on this! From page 70 of the International Code of Signals[2], we find that PG 2 means, "I am dazzled by your searchlight. Extinguish it or lift it."
Not bad, but what if you reply with "AX 1"? Lots going on there! "Shall I train my searchlight nearly vertical on a cloud, intermittently if possible, and, if your aircraft is seen, deflect the beam upwind and on the water to facilitate your landing?"
