Ray was a charming fellow although, being at opposite ends of the seniority list, I never had the opportunity to fly with him.
Some of the 727s had provision for a sextant sight. I well recall a flight over to Perth one dark night. The then chief nav was along for sextant recency. At each position, after he had completed his ritual incantations and pleadings to the Navigation God, I would pass over the omega (might have been INS - can't recall which tail we were on) lat/long for him to check.
Being the cheeky little fellow I was, the first was correct and subsequent massaged by several miles progressively worsening as the flight continued. There were mumblings from behind and quiet periods of rechecking calculations, as you would imagine.
When we approached the hills and he saw where we were the cockpit environment took a decidedly obscene turn. All was forgiven after the first round or two later in the bar.
