Gretna Green is a Scottish village famous for the bird “air shows”. Each year European starlings migrate to wintering in Scotland. Flocks of these birds soar and form bizarre shapes in the sky as if they were dancing. Many come to witness their unusual twists in the air.

These are photos of the US Air Force Thunderbirds in Romania at the 2011 Constanta Air Show. They are nothing short of majestic as they perform back to back mirror flights high overhead. They are truly amazing pilots and aircraft.
