A lot of this can be blamed on untrained observers, as your average Joe seeing a UFO isn't likely thinking about such things, and so doesn't recall
the detail as important. He remembers what the sound sounded like, but not necessarily when it was first heard.
Also, in many encounters, the UFO is not that high, and so it's likely the time between sound and sighting goes unnoticed by the untrained
observer...so when the sighting is described, it doesn't enter into it....
