I can confirm the 24 Dec 1990 issue of AW&ST did publish an article entitled "Scientists' and Engineers' Dreams Take to Skies as 'Black' Aircraft" written by William B Scott. It mostly discusses an unmanned diamond-shaped hypersonic vehicle that, according to the article, could have already bern flying by the date of the article. I will send Joerg a photo of a paragraph from the article that describes the aircraft.
