I used to take my chopper to a North Sea oil rig
where some of those riggers were quite big
I often had trouble with them getting on
as their equipment could be quite long
I would take them from the rig back to land
where getting them off took a helping hand
tired they would often collapse to the floor
while I would fly back to pick up some more.
