Today I Learned about the
Cessna 188 Pacific Rescue, which occurred on Dec 22, 1978.
The Cessna 188 is a single seat "agricultural aircraft". It's a crop duster. And this one was being delivered (flown) to Australia from the U.S.
The pilot became lost over the Pacific ocean due to a malfunctioning Automatic Direction Finder. When he arrived in the vicinity of Norfolk Island, the island wasn't there.
Random note: Wikipedia gives the range of a Cessna 188 as
370 miles.
The only aircraft anywhere near the area was Air New Zealand Flight 103. When the pilot of the DC-10 learned of the predicament, he knew that if they (the crew) didn't do something to help the pilot of the Cessna he would almost certainly die.
How they helped the guy is a short, interesting read.
