London ambulance crews are now using underwater drones during training exercises to improve rescue operations. The remotely operated devices offer real-time video feeds and can assess water conditions, helping rescuers locate and retrieve individuals in distress. This technology is being tested in rivers, lakes, and canals where traditional methods may be less effective. The drones can also assist in pulling casualties toward safer areas, potentially reducing response times and increasing survival rates. The initiative reflects a growing trend of integrating advanced technology into emergency services to enhance public safety.
