That's a far cry from the claims of "circled the >> globe" and FOBS as outlined in the article. China is now saying it does refer to the July 16 spaceplane test, according to reports: https://twitter.com/StephenMcDonell/status/1450008739512295427?s=20 About the "suborbital" character of this test: I realised it might not have been suborbital at all. While it landed 800 km from the launch site (which was interpreted as "suborbital"), this could in fact have been at the end of the 1st revolution. I was indeed able to create a ~41.2 deg inclined hypothetical TLE for a Jiuquan launch that at the end of the 1st rev ends up near the indicated landing area (Alxa League).
