UAVs appears in many forms, from tiny quadcopter toys to winged planes and even 7-ton aircraft that can stay up high for 34 hours at a stretch. As the time passes, the drone industry innovates and left us with awe-inspiring views and images. Universities, businesses, military agencies are testing larger and more capable drones that'll operate autonomously. The software and hardware plays a major role, that lets developers create instructions, test reactions and refine aircraft responses. But the systems need to be tested both in real life situations and in simulations, in order to handle a wide range of aviation solutions and to withstand cyberattacks.

Would you get on a plane that didn't have a human pilot in the cockpit? Half of air travellers surveyed in 2017 said they would not, even if the ticket was cheaper. Modern pilots do such a good job that almost any air accident is big news, such as the Southwest engine disintegration on April 17. But stories of pilot drunkenness, rants, fights and distraction, however rare, are reminders that pilots are only human. Not every plane can be flown by a disaster-averting pilot, like Southwest Captain Tammie Jo Shults or Captain Chesley "Sully" Sullenberger.
