ARJ21, China's first domestically developed regional jet, completed its first highland test flight in southwest China, between Kunming, Lijiang and Xishuangbanna on Aug. 19.

Designed to adapt to the highland conditions with high anti-crosswind capabilities, ARJ21 can take off and land at the highland airports and avoid obstacles along the complicated air routes in southwest China.
