Meet the Little Ripper: a UAV that can drop emergency pods to save people’s lives. Its pods include water activated flotation and electromagnetic shark repellent devices. Land and Snow pods are also available to get people out of trouble in case of an emergency and keep them warm.
As it turns out, the Little Ripper was recently used in Australia to save two teenage swimmers by dropping an inflatable rescue pod down to them. Apparently, the whole process took 70 seconds to finish.
