I was asked to carryout a SAR mission whilst in the Falklands. Yes we did carry those super gyro binoculars (but they were broken). We stooged around at 10,000 ft (did not have fuel for lower) and guess what? Saw nothing.
Not that we could have done anything anyway other than plot position. As the position was well out of range of boats and helos nothing could have been done anyway.
