I see Tondelayo doing turns to go back to the Chino Airfield and Planes of Fame Museum every so often when it is here for a show. My house is on the start of the foothills for the Santa Ana Mtns about 10 miles straight south of the airfield and they use the cluster of about 6 pools that make our block a bright blue turning point from the air when on test flights etc. It has been low enough I had to back off the zoom on my camera and with just my eyes I could see the pilot looking down as he pivots around those pools. Once they did it in formation with two escorts in Marine and Navy colors.
