Summary
The Sky Walker seems to be a man walking in the air over Chicago, pushing a barrel-sized object. His appearance is associated with shattering glass, vanishing railroad tracks that cause a train to derail, the collapse of an office building and a pavilion. People panic, fearing foreign invasion. Inventors Max and Robert Gant are murdered by criminals, and Josh and Rosabel Newton, the Gants' servants, are enlisted by Benson to help in the investigation. The Gants invented a means of making a glassite airplane truly invisible (except for the engine) and a vibration mechanism that can reduce a target substances to hydrogen. The criminals use the plane and vibrator to cause the public to lose trust in any steel not made from ore taken from the Catawbi Range, controlled by the gang. The gang, well-organized and ruthless, almost succeeds. Benson disguises himself as a gang member, interferes with the plane's invisibility treatment, and frees himself and his aides from a death trap. The gang escapes in the now-visible plane, and is shot from the sky by the army.
Glass is a non-crystalline, amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide (CaO), also called lime, and several minor additives.
