"The four-ship Diamond is a legendary formation used by airshow demonstration teams around the world. The ThunderbirdsÕ version puts high performance fighter jets less than three feet from wingtip to wingtip, exhibiting the amazing skill of Air Force pilots. Although it might sound risky or daring, itÕs a safely designed and religiously practiced aviation art form. For spectators, it accomplishes its goal. From the ground, the four planes appear to float through the sky, similar to the way a school of fish swims smoothly through water." -afthunderbirds.com
