In all the reports I've read there is the common theme: "nobody had a clue; no signs of erratic behavior, etc.."
Well, I think there were red flags to be seen - beginning with his medical record.
Would you knowingly get on a plane if you knew that the pilot was taking as many as 8 kinds of prescription medications?
Excerpt:
".....Col. Williams also revealed to police in the interrogation that he suffered from chronic pain, a
condition that his co-workers and old friends have returned to time and time again when they’ve been asked by reporters about any changes they observed. Jeff Farquhar, Col. Williams’ former university roommate and one of his few close friends,
said he couldn’t help but notice about eight prescription bottles on the officer’s bathroom counter during a visit to the cottage in the summer of 2009.
“I got the impression that some of it was
painkillers, but there were
many different labels. I wasn’t snooping and I didn’t examine the labels,” Mr. Farquhar said. Other associates, such as Paul Ferguson, the program director at Belleville country music radio station Cool 100, recalled that at the annual wing commander’s golf tournament in 2009, Col. Williams, an avid golfer, couldn’t use a driver because he said it would ruin his back. ...." [Snip>]

First, what pilot who really felt the heavy responsibility for "all souls on board" would continue to put those souls at risk when taking so much medication? Seems to me that all the faculties necessary to pilot a plane would be somewhat affected by such medication; alertness, quick thinking, eyesight, physical reflexes - you name it.
Second, in my opinion, the base doctors who prescribed all that medication should have alerted the flight surgeon that RW should be grounded. Next thought is that, RW being the cunning person he has proven himself to be, probably went to non-military physicians for the prescriptions so they would not show up on his military medical record.
In the text of the interrogation by Det. Smyth, RW tells of flying on dates very near to his murdering JL, so it is reasonable to think that he was transporting troops "hopscotching across Canada" while under the influence of those prescription drugs.
To me that conduct underscores his total lack of concern for the souls he, and he alone, was responsible for. They did not matter when weighed against his advancement in rank and position - after all, it was predicted by those higher in the CAF that he was slated for the very top.
Oh, I forgot.... he was the model Commander; above suspicion.
