Back in 2005 two Flight colleagues -- Brendan Sobie and Andrew Doyle broke the story that China's Xian Aircraft Corp was developing a four-jet freighter sized between a C-130 and a C-17.
Nearly four years later, the always fantastic China Military Aviation site has posted the first images of the Y-20
It's perhaps worth noting that a California jury in July convicted Dongfan Chung, a former Boeing employee, of selling secrets about the C-17, among other things
According to Chinese web site, the Y-20 will weigh more than 400,000lb, placing the transport in an interesting gap between the 585,000lb C-17 and the roughly 311,000lb A400M
