This is probably the most beautiful part of the Thunderbirds air show. The diamond and number six pull up in a five-plane line abreast, then, seen here, near the top of the loop, six breaks away into his own loop in the opposite direction. When he does, one thru four change back into the diamond as they pass over the top of the loop, then come down to cross paths with six at the bottom of the loop. A very beautiful moment, made more so since the F-16s fly this to manuever to the country song 'Cross My Heart.'
