All rumour of course {-- Just This Once}
...well, rather odd that rumour is the only thing available to Canadian citizens, after a 10 month formal investigation. As a minimum, another brief interim report should have been issued, summarizing the status of the investigation & expected completion date.
Why the official silence and secrecy ?
At this late stage of a relatively straightforward mishap investigation... 99% of the available facts have likely been collected & analyzed. Either those facts are inconclusive... or the RCAF brass doesn't like the conclusions that those facts point to.
