Intercept over Austria

Several guys told me (including my father) they watched on local TV news that there was an article about Austrian radars picking up an udentified plane entering Austrian airspace. A pair of Saab Drakens was sent to intercept and what a surprise they saw. A military transport (possibly C-17 or a tanker) with two F-117s under its wings. There was actual Draken footage in the news. Anyone has more info on that one?

Also Slovenian radars picked up four F-16s violating Slovenian airspace last week, when they were returning to Aviano from somewhere over the Adriatic.
