Frying high: Chinese airline completes short-haul flight powered by gutter cooking oil
First passenger trip using recycled cooking oil beats Dragonair into the air

Hainan Airlines yesterday foiled Dragonair's plan to make China's first passenger flight using biofuel made from cooking oil.
The fourth-biggest airline on the mainland carried more than 100 passengers from Shanghai to Beijing in a Boeing 737 using biofuel made by state-owned oil giant Sinopec from waste cooking oil collected from restaurants.
In a statement, Boeing China president Ian Thomas called the flight "a significant milestone" in China's commercial aviation industry.

Cathay Pacific Airways subsidiary Dragonair had been planning on making history with its biofuelled Flight KA859 from Shanghai to Hong Kong on the same day. It appeared to have gained clearance when it announced on March 13 in a press release that it would "operate its first-ever commercial flight using a certified sustainable biofuel blend" on March 21.
