Mumbai, notorious for its traffic snarls, has achieved a first in the country after a city-based pizza outlet used an unmanned drone to execute a delivery by taking the aerial route recently."

All of us had read about (global e-commerce giant) Amazon's plans of using drones. We successfully carried out a test-delivery by sending a pizza to a customer located 1.5 km away from our outlet on May 11," Francesco's Pizzeria chief executive Mikhel Rajani said.

He stressed that this was only a test-flight but its results confirm that it can be used routinely in a few years.

A four-rotor drone took off with the order from its outlet in central Mumbai's Lower Parel area and delivered it to a high-rise building in adjacent Worli area, Rajani said, claiming that it is for the first time that the ubiquitous drone has been used for such a purpose in the country.
