Hangar pilots ARE the best ya’ know ...
WRT fly-by-wire versus cable. It’s a LONG way from the front of a 747/7X7/A-X00 etc to the rear of the airframe and the tips of the wings.
WHY use mechanical and/or hydraulic systems that weigh perhaps tonnes more, AND introduce lag, slap and wobble from stretched cables and worn fittings? Think Stearman ;-)
I have more issues with different brands of engines than I do airframes. I don’t like the harmonic whine of RR engines on the big birds at take off power. It hurts my ears. Once in flight on cruise, no worries. But climb out is painful if I am sitting in front of the wing.
