Crab:
Cyclic and J Knife - I was talking about the S61 v the Sea king not the L2 - as ever when a valid point is made (not exactly showing ignorance just stating facts) the other party moves the goalposts and then (jKnife) starts with the insults again.
Fair enough, however, you didn't make that clear in your answer and the original question was about "civvy SAR", hence the replies. Remember, as well as the Bristow/MCA contracts using the S-61, Bond Offshore have now started with their AS332L2s. Although contracted by an oil company, I fully expect they will be used where needed for non-oil related SAR work if they are the nearest asset.
With regard to FLIR, excellent kit and a great asset for searches. However, if the air is moist the capability of the kit reduces. Heat source against rocks should be OK, but looking for a body in the water becomes more difficult and sometimes impossible.
