Add to this that the trigger sound source was probably quite far behind the current position of the delta ????????? winged glider.
Also add to this that the sound was travelling a bit slower that day, putting even more distance between what the camera captured and where the sound source was.
Pardon?
Much more likely one hearing aid had run out of battery.
