The article is talking about flight-speed records in the context of powered flight entirely within Earth's atmosphere. The Space Shuttle of course get's credit for being one of the fastest-ever moving objects with people on board. It was also an unpowered glider during those speed records. It's simply in a different category. And technically the Apollo 10 crew did even faster at 39,897 km/h in 1969; which is over 10K km/h faster than the Space Shuttle controlled flight record.
