The article reminded me of the old and probably obscure roman de gâre "The North Cape" by Joe Poyer. https://www.goodreads.com/en/book/show/3430608 https://www.goodreads.com/en/book/show/3430608 It's set in the 60s with the pilot flying a new supersonic spy plane and dodging Soviet interceptors, eventually crashing guess where. He goes into a lot of detail about the plane, and specifically the different modes the engines have as the speed increases, which although fictional sounds very much like what they've actually done here. I think he acknowledged help from an aerospace expert in the plane design.
