The ground crew for the Air Force Thunderbirds sprint away from the aircraft after signaling them to taxi away for a practice flight at Andrews Air Force Base as they prepared for the 2011 Joint Service Open House and Air Show. They made history as two of their aircraft flew using a green/biofuel instead of the normal JP-8 fuel making the Thunderbirds the first DOD aerial performance team to fly on the alternative fuel.
