““finished, the cells were translucent. Each gas cell was like a donut, with a small hole in the center, through which the central catwalk would later be assembled. To keep the gas cells from applying direct pressure to the girder structure, which would have caused damage to the thin cells, a system of nets prevented the cells from touching the frame itself. This also allowed for inspections of the cells and the outer coverings. A distance of 20cm was thereby kept between the gas cell and the outer covering at all times.””
