Prospector: "In any case it was largely acedemic as all but one flight had approached Antarctica in brilliantly clear conditions and the final letdown was entirely VFR with no need for instrument cloud break procedures."
The question there is where was King getting his information from? You're talking about a second-hand source with a hefty dollop of opinion thrown in for good measure. I'd be surprised if he personally interviewed every single pilot that went down there over the course of time that ANZ ran those flights - many of whom found ANZ and Chippindale's report hard to stomach, given what they knew was going on, and testified in support of Captain Collins at the inquiry.
If the book is the one I've seen, which is a 300-odd pager referring to all aviation mishaps in NZ over a time period, firstly one would need to look at the sources - was Chippindale himself one of them?
