Alongside, connected to but not part of Joe Davies Historic Airpark is Blackbird Airpark.  On the south side of Palmdale’s airport, this area pays tribute to some of the most iconic products from Plant 42 across the airfield.  Lockheed’s Skunk Works turned out some amazing aircraft and this exhibit includes an A-12, an SR-71, a U-2 and an D-21 drone.  Having an A-12 next to an SR-71 is pretty special.  You have to look closely to see which is which.  A selection of black airframes together in the desert sun does not make for easy photography and there are lots of power lines and fences in the background but it would be churlish to complain too much.  It is free after all!
