NASA is hoping to use drones to speed up organ delivery for transplant patients.
A flight test earlier this month at NASA's Langley Research Center in Virginia saw a drone pick up a kidney and fly it for the first time beyond "line of sight", or the distance from which a drone is visible by an operator. Keeping a line of sight on a drone is a typical requirement for flight safety, but NASA is developing tools that may allow these machines to fly further away from operators in populated environments more regularly.
