In the UK, some of them have tried stealing the copper overhead catenary from
the railways - even when it's live at 25kV! Some learnt and now they short the
line to ground first.....
A guy I worked with at the old Decca Navigator company many years ago told the
tale of an airport in Argentina where an ILS system was installed in the mid
1960's. A few days later, at around 5 am, the alarm went off to indicate that
the outer marker beacon had gone off the air, as had the standby. Investigation
showed that thieves had pulled the armoured buried mains supply cable out of
the ground for the copper - about a mile of it!
So there's nothing new.
