Pizza, porn and whale snot: seven alternative uses for drones

News that a British Airways plane was hit by a drone before landing safely at Heathrow airport has once again highlighted how drones can be a nuisance and, potentially, dangerous. We all know about the military uses of drones (bomb lots of people, surveillance), and how drones can be used for nefarious purposes (theft, voyeurism), but there are actually some pretty cool uses for drones too. Last year the Ocean Alliance partnered with tech heads Yuneec to create "snot bots"; drones with petri dishes attached. For research purposes, the drones are flown over water to catch spray and snot from whales when the animals exhale. There is already a drone journalism lab at the University of Nebraska-Lincoln and the University of Missouri also offers a drone journalism course.
