   • 2013 September 6, Tom Cheshire, “Solar-powered travel”, in The Guardian Weekly, volume 189, number 13, page 34:

     The plane is travelling impossibly slowly – 30km an hour – when it gently noses up and leaves the ground. With air beneath them, the rangy wings seem to gain strength; the fuselage that on the ground seemed flimsy becomes elegant, like a crane vaunting in flight. It seems not to fly, though, so much as float.
