In the 1990s my dad who was a CFI belonged to a glider club where he flew the towplanes on weekends. One time he was preparing for aerotow and the marshall signaled for him to takeoff which he did. Unfortunately as soon as he became airborne he recognized something was wrong as the tow rope was pulling him sharply down and to the right to the point that it exceeded rudder control. The glider on tow was high and out of place so, worried about being pulled tail-up, he released the rope and returned to the airfield. It turned out that the marshall had mistaken the glider pilot fumbling with his seatbelt as a thumbs-up and the glider was pulled into the air with its canopy wide open. 😂
Same way here in Canada, except where I work at an FBO the aircraft will call us on our own frequency about 20 - 30 mins before he lands and tell us what he needs (ground power, fuel, lav service, potable water or anything else he needs) So we only have to use the basic maneuvering signals when marshaling. It's pretty scary to be stood up in front of a C-17 when your marshaling it. Especially when you give him the command to reverse and push back under his own power you can feel the ground rumble!!
I am looking for detailed info in ways that pilots could communicate to people or troops on the ground. A classic example would be a fly by while nodding the wings Is it possible for planes to change their sound pitch based on the descendant , angle, or throttle level. This would allow for pilots to communicate crude signals or warnings or possibly morse code to ground troops or personnel. An example of such scenario would be an agent in enemy territory. A plane flying in the area conducting reconnaissance that is a double agent then making a specific sound to warn of a returning legal or military patrol giving the agent time to hide in place to avoid the return of the police or military patrol

Ah yes, fighter jet morse code.
Fire machine gun for dot, missile for dash.
Marshall : stop
Me: *no*
