An anonymous reader writes: Less than two weeks after we heard about the "robotic dragonfly" project failing, the BBC brings news that an even bigger crowd-funded drone project has given up development as well. The ZANO mini-drone raised a whopping £2.3 million on Kickstarter ($3.5 million), after asking for a mere £125,000 to get off the ground. They were supposed to start delivering drones in June, and a few hundred of them slowly trickled out. In October, they posted a long update detailing their plans for shipping the other ~15,000 drones they had been paid for. Their latest update, posted today, says, "Having explored all options known to us, and after seeking professional advice, we have made the difficult decision to pursue a creditors' voluntary liquidation." This will leave thousands of backers without a drone, despite paying £140 or more apiece.
