AuxSound2

The sound a structure makes as it starts folding away, and the sound a flying object makes as it comes in to land.

Specification

[MYHELI] ; an AircraftType registered in [AircraftTypes]
AuxSound2=MYHELI_Landing ; a sound ID registered in SOUND.INI

Two unrelated paths read the same slot:

A structure plays it at its own position as a deconstruction begins — a sale or an undeploy — once its animations have stopped and an IsJuggernaut=yes structure has finished returning its body and barrel to their start values. The reverse build-up follows it; on a sale that puts out no vehicle, the crew evacuation comes between the two.
An object flown by the flyer locomotor plays it once per landing, at the ground under it, as it drops below 300 leptons, and only while it still has strength left. A wreck falling out of the sky lands silently.

Nothing else reads the slot, so on a ground vehicle or an infantryman the setting is inert.

A name that matches no registered sound leaves the previous value in place rather than clearing it.
