Crab,
Has civvie Sar failed in a mission yet?
If not.....perhaps their standard meets the necessary requirements.
The absence of Night SAR capability is antoher question altogether as it is about capability and not training.
The question that is begged is what happens down the road...years down the road if the Civvie SAR does finally get that night capability but has not done any or done any training for that mission. Then what problems will have to be confronted?
