The drone industry (Part one) The past few years, on the cusp of a new round of technology explosion, have witnessed the rapid development of the drone industry. Gone are the days when these flying little gadgets made their appearances only on screens, often used as future human's weapons in some science fiction films. Every individual, nowadays, can buy one, and with a simple registration process, fly it into the sky. As with other dual-use technologies, drones can be either hovering saviors or menaces. On one hand, civilian drones are saviors that have helped people trapped by natural disasters, as they did last year when two young men were saved by a patrolling drone off a beach in New South Wales during their struggle against the violent surf. On the other hand, drones can also endanger life and cause disruption. For several times, they have been the ones to blame for forcing airports to shut and helping criminals to smuggle contraband across borders and into prisons. The bad often comes with the good. Not until the bad uses of drones are prevented can the technology be fully embraced for extensive commercial use.
