Adm Davor Domazet-Loso, Croatia's military chief of staff at the time, claims Chinese agents took parts of a downed F-117 stealth jet in 1999. The F-117 had been shot down by a Serbian anti-aircraft missile during a Nato bombing raid. China's J-20 stealth fighter had its first test flight earlier this month. Currently, the United States is the only nation with a fully operational stealth plane. |
