How cool is this? Much like you get concept cars, you also get concept aeroplanes... and designer Reindy Allendra's KLM WB-1010 is the most eye-popping paper plane you'll ever see. Inspired by blue whales and blimps, the plane will have supersonic engines and a helium-injected body, and will carry 1500 people at a max speed of 620 miles an hour.
Of course, it'll never fly.
But it's nice to dream.
