very lucky escape
This one came up a few months back.
The Enstrom was operating from a greenpeace ship - there was much debate about proper helideck procedures.
The consensus from the professional helicopter pilot fraternity was that no suitable safety procedures appear to have been followed here and that the guys on the ground were even more lucky to be alive (and not decapitated) than the ones in the chopper (and that is saying something) whose tail rotor probably struck the deck after one of the skids had become entangled in the netting.
