I had occasion to fly out of Heathrow a month ago on an Airbus A380 giant. After we broke ground on the climb out I shot this cool video of the left inboard engine's nacelle strake generating its vortex trail back over the wing. I was surprised at the boundary layer thickness. It's hard to scale due to the size of the wing but there was actually about 2 feet between the wing and the trail. Thought everyone would enjoy some pilot-aero geek stuff. Sorry it wasn't edited better.
