Skill, timing, and the sun came together in this air show photograph by Bernardo Malfitano
An F-22 at Miramar at the top of a loop. He is pulling so many Gs, the low pressure air over the fuselage (that is "sucking" the airplane into the loop) gets cold enough for the water to condense... And the angle is just right for sunlight to undergo total internal refraction and make rainbow colors around the airplane (although I had to under-expose quite a bit for the effect to be visible).
The picture won second place in the Museum of Flight photo contest. Link -via reddit
