I am led to believe that a mainland SAR crew would probably have taken less time to effect a rescue than did the Jigsaw but I don't know how much night training they do for the job and it is better to take a little time rather than end up in the water alongside them.
A point of C2 was highlighted since the rig acted as On Scene Commander which rather put the Nimrod's crews noses out of joint - a good learning point for them since civilians don't have to adhere to military SOPs.
