[edit] Summary
During an aerial demo at the Pacific Coast Air Museum's 2005 "Wings Over Wine Country" airshow, an F/A-18 Hornet does a high-g pull-up. The high angle of attack causes powerful vortices to form around the edge of the leading-edge extensions of the wings. These vortices cause the air over the wing to be turbulent, preventing stall and allowing the Hornet's wings to generate lift despite these unusually high angles of attack. This makes the Hornet capable of extremely tight turns over a large range of speeds.
In this image, a drop in pressure results in a drop in temperature severe enough to condense the water in the air, making the vortex visible as white "vapor".
