Amazon shares rose 1.48% to $255.62 as Prime Air filed for approval to expand drone deliveries from part of Darlington to the entire County Durham town. The company has completed more than 500 flights and deliveries since launching limited service in February and expects a Civil Aviation Authority decision soon. The current operation covers customers within a 7.5-mile radius, with eligible orders delivered in as little as two hours. Packages must weigh under 5 pounds, fit inside a large shoebox and be deliverable to a suitable garden, yard or driveway; Amazon estimates those limits cover about 68% of orders. MK30 drones fly at around 400 feet and can operate in light rain, light snow and wind gusts of up to 28 mph, while flights stop in unsafe conditions. Prime Air is included with UK Prime membership for now, although Amazon may review pricing as coverage expands. The Darlington trial is also being monitored after a July crash into a garden caused no injuries. Broader approval would support Amazon’s ambition to build a UK-wide drone delivery network and provide a test case for expansion in other markets.
