Originally posted by RobG Bummer! That would have been a cool photo! Funny you mention Edwards; I was trying to figure out what base I saw from a flight approaching San Francisco back in 2002. It had a dry lake runway, but the base didn't look like Edwards. I was reminded of it recently while looking at the video. Shortly afterward, the flight passed over Yosemite; Half Dome and El Capitan were easily recognisable.
Sound like one of the smaller dry lake beds in the Owens valley on the east side of the Sierras,
Where were you coming from on your way to San Francisco?
I don't think the military is maintaining those lake beds as much any more, but at one time they had several up the east side of mountains, toward Death Valley, and Owen's Lake. Were part of the emergency landing network for the X-15 program, and other High Altitude, High speed flights.
Edwards is further south, just north of the mountains above Los Angeles.
