pretty planes

Contra rotating props I understand. Still from what it shows even at low video speed it looks like they are feathered for reverse thrust.
Could a strong wind blow the props 'backwards' while parked on the tarmac?

Love to know the story as to why that spy plane was being towed down a country road.

9. Years of Darkness. In addition to flying secret missions in its previous life, the SR-71 was stored in a custom hangar built solely for its protection in a secured area of the Dulles Airport property after it was turned over to Smithsonian. It remained there for over 10 years until the Museum had a display facility where it could be viewed by the public - the Steven F. Udvar-Hazy Center.
