"2 - see the flooring. It's those d@mn wood blocks. They were nasty.

They were hardwood, like 4x4 chunks set on end, and coated with something like creosote.

I'm not sure what the motivation for using them was; perhaps because they could be removed easily for assembly line rerouting at model change, or for repairs, or to provide some "cushion" if material (or a vehicle) got dropped.
But they were hard to walk or stand on all day, uneven, slippery, got the sealer all over everything, and made the area dark.
I used to take my shoes off and set them in the truck bed before getting in and wear clean shoes into the house. When I got to work the next day I'd remove my clean shoes, put on my steel toed Redwings and head back in.

You are SO! correct. FWIW You Taxpayers continue to employ these floors continuously since 1930 at your Four Public Naval Shipyards. (*Talk about getting your monies worth.) The wood blocks allow for easy access to utilities and modifications to IPE industrial plant equipment "Floor plans". They are interlocked by a rabbet cut into the blocks making a stable surface for protection of precision parts unintended gravity drops and recoveries. They floors Stink forever! The Buckle when roof or inside gutter-downspouts leak.
