Reader B pointed out in comments of the last post that weights were needed to ensure the nets had enough elevation and fully deployed.
The picture in my head is of something like a CO2 cartridge that is pre-scored and holds the compressed net within. The package is shot out of a shotgun with a rifled barrel to impart a spin. At the desired elevation, a chip-and-charge detonate and the sides of the CO2 cartridge unzip to become the weights that spin out the net.
|The important thing to notice here is that she draped some of the net weights over her left shoulder. Those weights will have much lower velocity than the weights she is slinging out and will impart a spin.|
