Efficiency in Rescue Operations:
- Aircraft like helicopters are specifically designed for search and rescue operations in challenging terrains and adverse conditions.
- They can airlift people to safety, deliver essential supplies, and provide medical assistance in emergencies.

Versatility and Adaptability:
- Air transport can be used for a wide range of purposes including medical evacuations, humanitarian aid, firefighting, and disaster relief.
- It can adapt to different situations and requirements, making it a versatile tool for effective response to emergencies.

Capacity and Reach:
- Air transport has the capacity to carry large numbers of people or heavy equipment over long distances in a short period of time.
- This ability to cover vast areas quickly makes it indispensable in reaching individuals in distress during calamities.
In conclusion, air transport plays a crucial role in providing assistance and support during emergencies and in reaching inaccessible areas where other modes of transport may be limited. Its speed, efficiency, versatility, capacity, and reach make it an essential tool for rescue operations in times of need.
