Re' the NDB, MacJob's _AD_ [Vol2, pg73, mid], contrary to the ANZ briefing, the McMurdo NDB was actually still operative during Nov'79 mishap.
That's interesting. I wonder why they'd have told ANZ that it had been withdrawn - although it might be that it had been officially withdrawn while still technically operative. I read that the US base weren't particularly happy about the sightseeing flights.
