United States F-16 jet fighter pilots were "reminded of New Zealand's aviation rules'' after low flights over Fox Glacier sparked safety concerns from West Coast helicopter operators.
The pilots raised the hackles of locals during their visit for the Warbirds Over Wanaka air show.
It is understood the F-16s, on pre-show training flights, approached the area from the south, flying close to tree level as they neared the glacier.
The Civil Aviation Authority said yesterday it received complaints from tourism operators in the Fox Glacier and Franz Josef areas about low-flying F-16s.
"We understand the Royal New Zealand Air Force reminded the pilots of New Zealand's aviation rules, after which no further incidents occurred.''
