Korea sets sights on runway-free aircraft after record-breaking drone flight

Korea is pushing ahead with plans for a new generation of aircraft that can take off and land without runways, following a record-setting seven-day flight by its solar-powered unmanned aircraft in the stratosphere. The Korea AeroSpace Administration (KASA) announced Wednesday that it will pursue development of hybrid vertical takeoff and landing aircraft after its EAV-4 unmanned aerial vehicle completed 170 hours and 5 minutes of continuous flight from Aug. 18 to 25. The achievement more than tripled Korea's previous domestic endurance record of 53 hours, set by the EAV-3 in 2020, and ranked second globally behind Airbus' Zephyr, according to the agency. During the flight test, EAV-4 also demonstrated wildfire surveillance capabilities, using electro-optical and infrared cameras to identify ignition points within seconds and track and predict the direction of smoke and the movement of embers. Flying at an altitude of about 20 kilometers, solar-powered stratospheric aircraft can remain airborne for extended periods, potentially serving as persistent surveillance platforms and emergency co
