Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did LSO's use to signal corrections to the pilot prior to the angled deck designs introduced in the 1960's?
Ah, so.. unanswerable
