The B-52's I maintained for a lot of years had over 100 miles of wire onboard. Most of the connections were soldered. Battle damage to wiring harnesses got crimped connections at times, mostly to get a bird back into the flying schedule quickly. Even then, we had very specific procedures for crimping and insulating repair work. One memorable fix to a star tracker wiring harness over the bomb bay involved a sheet metal repair of some flak damage- - - -the tin bender hit our wire harness 17 times with a 1/8" drill bit while applying a temporary patch to the top of the plane, and the harness had over 100 wires in the bundle! The crawl space over the bomb bay where we were working was about 18" tall, the plane was painted black, and it was in the middle of summer in Okinawa!
