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)?

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.
