Leaving to one side the specifics of this exercise which have been discussed, can someone explain why what looks like civilian contractors are practising for a task that you would think should be being conducted by the military? Are there not issues with vetting for the pilots and the maintenance of strict secrecy before and after an event? Would the contractors have the ability to use a night vision device were such a task to (sensibly) take place after dark?
Sorry to ask such questions but from 12,000 miles away it looks a little strange to see what I'm assuming is a counter-terrorist team swarming down ropes from a bright red civilian helicopter in broad daylight to a passenger ferry where their planned technique can be recorded and broadcast to the world.
