That stat about wiring harness weight on the 737 caught me off guard
I was looking through some old training manuals from the 80s I found in a bin at our hangar in Detroit, and it said the 737-200 had around 500 pounds less wiring than the NG models. That really surprised me, all that extra copper adds up fast. Has anyone else run into old specs that made you rethink how much things have changed?

Man that really puts it into perspective, I had no idea the difference was that big between generations. It's wild how those little changes add up over time.

Yeah guess that explains why my back hurts just from SITTING wrong these days.

Nah I gotta push back a little on that @the_hayden. Yeah the weight difference is real but it's not like those old 200s were lighter in a good way - they just had way less tech crammed into them, so all that weight savings went into making them do less stuff. The NG systems have way more redundancy, and redundancy adds up fast when you're running triple or quadruple everything through the whole airframe.
