Another first time by SSG Version 11!, will we see another?
First, it is "you're", not your. It is a contraction, not the possessive.
Second, I am proud to be associated with Pprune members, such as mutt, Brian and FEHoppy. Can we add Old Smokey, if so, I am humbled?
Third, which way does the rotor thingy go?
Fourth, barit1, the only bearing failure I have heard of, as a design failure was of a military jet. A friend, tech rep and bearing engineer at the manufacturer and ANG pilot, was handed a handful of obviously broken parts, reported to be a main bearing. Asked what the original bearing looked like and a set of drawings, was told that he didn't have a clearance to see them. "Then, he replied, it broke.". j58, btw.
