Google has agreed to purchase for an undisclosed sum the two year-old start-up maker of high-altitude solar-powered drones Titan Aerospace, based in New Mexico. Titan claims a number applications for its drones, including data delivery, crop monitoring and search-and-rescue aid. However the unmanned aircraft can remain in flight for as long as five years without having to land or refuel, which has led to them being classed as 'atmospheric satellites' with corresponding communications potential.
