Very sad news. Chris epitomised the phrase an Officer and a Gentlemen. Few people who have travelled his career path did so in such a pragmatic manner keeping their ego and feet firmly on terra firma.
He did my first ever trappers ride; the only sortie I ever left the chocks in a field in Germany. .... and yes I was directed to ensure the wheels were replaced inside the chocks at the earliest break in tasking without physical human input. Lesson learned, along with a confidence retaining comment of: " There are those who have, there are those that will, and there are liars".
I never did it again, though skids on the Griffin helped!
RIP
