TRAITOR: A former Stanford aerospace chief who helped oversee F-22 and F-35 engine development spent nearly a month training researchers at a blacklisted Chinese defense university!! Brian Cantwell chaired Stanford’s Department of Aeronautics and Astronautics and served for 14 years on the team reviewing the engines that power America’s most advanced fighters. In May and June 2025 he traveled to Beihang University under a Chinese foreign-expertise recruitment program. Beihang records show he gave six technical lectures, advised graduate students and research teams, toured laboratories, and discussed unpublished work. Beihang has been U.S.-blacklisted since 2001 because of its ties to China’s military and missile programs. America spent decades trying to keep sensitive aerospace knowledge out of that university. China simply invited the expert who helped build the engines. This is not academic exchange. It is a national-security failure that handed a key American technical mind to an institution the U.S. government itself has long treated as a threat. #ChinaThreat# #NationalSecurity#
