I see military aircraft all the time. But i've heard a number of reports lately of low flying aircraft along the coast line. Last week two flew over downtown in midday. On NY day, some friends were hiking at wilder ranch, and reported low-flying aircraft. Later that night myself and a friend were on 14th and portola. We saw two aircraft similar to those pictured above, flying south on the coastline. It is likely the increase in activity through this area is related to the rescue operation, or possibly something worse?
