China's top helicopter pilots have been showing off some unusual skills in the national chopper tournament in the city of Laiwu in eastern China.
The culmination of the three-day event involves using a bottle opener attached to the helicopter's skid to de-cap a bottle of beer on top of a pole.
Competitors must open a sequence of five bottles within eight minutes and the one who opens the most bottles wins the game.
One pilot made it look like easy work, flipping the cap off after only a few attempts:
Unfortunately he fell foul of the competition's strict rules that do not allow the bottle to be damaged.
