In December 2013, Amazon CEO Jeff Bezos appeared on "60 Minutes" and unveiled Amazon Prime Air, a drone-delivery system that he said could transport packages to customer doorsteps in 30 minutes. Bezos said more safety testing and federal approvals were needed, but he estimated that Prime Air would be available to customers in as soon as 4 to 5 years. What's up with that project and other civilian applications of unmanned vehicle technology? Sean Gallagher, Baltimore-based IT editor of Ars Technica, recently attended two drone conferences, including one in New Orleans that featured Amazon Prime Air vice-president Gur Kimchi. Sean joins Dan to talk about drones in work, play and warfare.Links mentioned in the podcast:• The Dronebuster (http://arstechnica.com/informationtechnology/2016/05/dronebuster-will-let-you-point-and-shoot-command-hacks-at-pesky-drones/)• Marines' autonomous robot-drone (http://arstechnica.com/information-technology/2016/05/by-our-powers-combined-marines-test-teams-of-autonomous-robots-drones/)• FAA's progress (or lack thereof) on drone rules (http://arstechnica.com/information-technology/2016/05/faa-chief-announces-advisory-panel-on-drones-as-industry-checks-its-watch/)• Air traffic control for drones (http://arstechnica.com/information-technology/2016/05/by-mapping-the-skies-airmap-app-paves-the-way-to-a-drone-filled-future/)
