The experts cited in the article are some of the most well-known researchers in the field of aerodynamics. John D. Anderson is the author of 7 reference textbooks, all of which are commonly used in the field. His research took him from the US Airforce Aerospace Research Laboratory to the becoming the Chief of the Hypersonics Group at the US Naval Naval Ordnance Laboratory. He was Chairman of the Department of Aerospace Engineering at the University of Maryland. He is a member of the National Academy of Engineering for aerospace engineering. His name is attached to enumerable scientific journals that I encourage you to search through if you think that an average Hacker News user knows more about aeronautics than him.
