Why are engineers crawling through Jeffereries tubes with gravity plating on, not just on, but at full gravity? You can't tell me gliding down those things wouldn't be faster, easier on the knees. And its a easy fix for cameras. Tie some fishing line on a tool, make it float. Harness on a actor, zip him down a line- tilt him upside down or wear a hat for hair issues. Floating ponytails can't be that hard. Seriously, just no excuse why elderly Scotty had to crawl. That's inhumane. Just float and push off. I saw they made Archer float a few times on a TV show, it's technologically feasible for a modern film crew on the cheap to do. I don't want to see another starship on the verge of destruction as a engineer crawls, leap headfirst into that tube and zoom fast. Adds to the drama.
