Hey - Im Goggs biggest fan and totally agree with you that they make a world of difference (although your comment that using Goggs makes it flying like day would receive a short rebuke from the old man at CAM who used to reiterate that the only thing that made the night look like day was the sun).
But at the end of the day SAR crews indeed a lot of helicopter crews all around the world are flying aroud at night conventionally and doing it very safely.
