UP IN THE SKY: It's a bird...it's a plane...wait. It's a book. Aussie startups Zookal and Flirtey announced plans to use unmanned drones to deliver print textbooks in the Land Down Under. Zookal CEO and founder Ahmed Haider claims this can cut delivery costs from $8.60 AUD to 80c and get textbooks in customers' hands in as little as two to three minutes. Customers will be able to track the drone's location via GPS on their smartphones. (Unlike the U.S., Australia allows the use of drones for commercial purposes.) No word yet on what happens in the event of accidents or if it gets shot down.
