Researchers build sailboat drone prototype that can 'fly' — we think it's more like falling with style

ALBATROSS turns an aircraft release into a controlled ocean landing system The 1.1 kg drone can deploy without carrying powered flight hardware Its rotating descent slows the fall before the vehicle reaches water ALBATROSS, a drone built by seven engineers at Singapore university SUTD, is a lightwei
