GUANGZHOU — China’s first domestic-built large amphibious aircraft, the AG600, completed its second trial flight in South China’s Guangdong province on Jan 24.

The aircraft AG600, code-named “Kunlong,” successfully finished all tests during the 73-minute flight on the morning of Jan 24, according to China Aviation Industry General Aircraft Co. Ltd.
