Lifeguard drone dropping float into water close to two swimmers in trouble

In a first lifeguard's drone saves swimmers in Australia

Just before midday local time, a member of the public spotted the 16 and 17-year-old boys caught in a rip current in rough seas off Lennox Head, a beach popular with surfers about 750 kilometres (466 miles) north of Sydney.

A Westpac Little Ripper Lifesaver drone was quickly launched and directed to the boys' location, where it deployed a life raft then used by the pair to get back to safety. The call for help just so happened to have sounded as a group of nearby lifeguards were undergoing training in the use of drones.
