The August First Aerobatic Team of the People's Liberation Army Air Force has also paid tribute to China's fallen heroes on Martyrs' Day. The team performed a series of stunts Thursday morning at Airshow China in the southern city of Zhuhai. Pilots guided J-10 fighter jets through loops and rolls. And they presented a white flower in the sky with aero-smoke to commemorate those who have sacrificed their lives for the country. The airshow, held from Tuesday through Thursday, is the only international aerospace trade show in China endorsed by the government.
