You can also see the engineers in remote places like jungles (strictly not for fun i.e. hunting) or near the gas fields or in the middle of nowhere like sea. Sometimes you can even see the engineers standing on the top of the broadast tower, shouting to the person down below not yet to turn on the power (happens when you forget to take the walkie talkie)
Last time I saw an engineer going two kilometres deep inside the sea trying to find the ROV. Since then scuba diving is off my list.
