On 10 october 2016, my son received from a friend an 8-second video of the blue angels show in san francisco, ca on 9 october 2016. the video was shot from the marina district, southeast of the golden gate bridge, facing san francisco bay. near the end of the video, my son noticed an object move very quickly through the frame from left to right at about the same altitude as the blue angels jet that was being filmed. my son's friend never mentioned seeing the object and was simply sharing the video. the video was taken by an iphone 6 and appears in only 2 frames. the "object" was approximately the same size as the jet and appeared to be saucer-like or a flattened oval with a relatively tall tail section. the "object" looked very much like luke skywalker's landspeeder, but with a taller tail section. the "object" doesn't appear to be an insect whipping through the frame of view. it appears to be just below the jet and a little closer to the camera than the jet. the speed of the object is unknown, but appears to be extremely fast, such that it couldn't be seen with the naked eye. i lack good video software so would appreciate a more detailed analysis of the object to ensure it wasn't an insect or other known object. thanks.
