That's a very good statement. In addition to this, there is enough time to navigate a certain area without any hesitation that a life will be at stake. At a given time, the drone can locate a certain victim and by this method, rescuers saved a lot of time on finding large numbers of survivors and great possibility that no one will die because they are not found as quickly as possible.
Their versatility makes them easy to deploy and use in a rescue operation. Drones are very effective to use over complex areas, inaccessible and risky location. They can fly in and move around to get real-time footage of a disaster area that can be used to assess the damage.
