There is an argument that operations of an immediate nature where lives are at risk normally do involve the use of plans and helicopters already and therefore, there is no point doing the same operations with drones, especially since they can’t carry any rescue personnel with them on their operation. However, there are a number of points that go in the favor of drones as compared to helicopters and planes. There are a few facts about planes and helicopters that points out why it becomes too difficult to use them in some operations:
They take some time in getting deployed They consume a lot of fuel and prove very costly They need a human pilot to be sent along with them in dangerous situations They cannot get very close to the emergency as they need to maintain a definite vertical height to avoid crashing.
