Amazon CEO Jeff Bezos recently revealed to CBS-TV’s “60 Minutes” that the world’s largest online retailer is developing a delivery system that would use unmanned helicopter drones to deliver packages via air to people’s homes within 30 minutes after they submit their online orders. While Bezos admitted that the futuristic delivery system was still several years away from becoming a reality, the announcement has sparked a flurry of online commentary about it’s potential impact on the materials handling industry.
