In video of the incident taken from the drone, it can be seen releasing a yellow “rescue pod” that inflates in the water. The two swimmers grabbed the pod, and with its support they made their way to shore. They were fatigued, but not hurt, Surf Life Saving New South Wales, a volunteer organization, said in a statement.

In the future, our robot overlords may make even lifeguards obsolete.
