Is there any coincidence between the scene in "Alien Prometheus" where the engineer pilot ignites the spacecraft by a piccolo and 1960s phreaking(2600 Hz whistles)? https://www.youtube.com/watch?v=NegOHzcBlHQ (1:09) btw, In the real world, in addition to the early Ma Bell telephone system(in-band signaling), are there any complex systems that are controlled by tones (not human voice)? | |||||||||||||||||||||||

Any sort of system where you have an band limited audio channel and need signalling is going to end up using tones. DTMF is a lot more robust, but single frequencies work too. See also https://en.wikipedia.org/wiki/Quindar_tones | |||||||||||||||||||||||

Oooooh... so that's why that hacker magazine is called 2600. I honestly didn't know. | |||||||||||||||||||||||
