This is interesting. The F-117 Nighthawk was officially retired over 6 years ago but there have always been rumblings that several of the models were continuing to fly sorties of some kind. Now new photos have emerged proving that there are at least 2 F-117s making regular flights from the Tonopah Test Range in Nevada.

The aircraft flew on Sept. 29 using radio callsign “Knight 12″.
Why some F-117s were kept in flying conditions and still operate in secrecy (although during daylight…) more than 6 years after their official retirement remains a mystery.
