Here are four aircraft photographed in various times in various locations of San Francisco Bay Area. The Ford 5-AT-B Tri-Motor was photographed in Hayward, CA during the EAA visit to that airport. The General Motors FM-2 Wildcat was photographed on board USS Hornet in Alameda, CA. A very early Douglas A4D-1 Skyhawk is a gate-guard at the former NAS Alameda. And finally the Lockheed ER-2 (NASA version of the U-2) was shot at Moffett Air Museum in Sunnyvale, CA.
