Now, let's try to better define both size and distance to the camera of this object.
In the testimony, the guy said that they were stopping at the "black mailbox", which is not visible on the photo.
So, looking at the position of the stop sign, the roads, the distant mountains on the background, we can reasonably assume that the guy who was taking
the shoots were close to the mailbox.
Using Google Maps and Streetview (it's hardly visible on the aerial views, but it's there), one can gives a good estimation of the distance between
the mailbox and the stop sign:
It's roughly 20m/65ft.
Next step, using my favourite software and this methodology
, is to calculate the possible sizes/distances
to the camera of the object in the 3 images:
So, the angular size of the object is comprised between 1.009 and 1.417°, meaning that object's diameter estimation is, for a distance of 20m/65ft
comprised between 35 and 49cm and less if it's closer:
- between 26 and 37 cm for a distance of 15m
- between 17 and 24 cm for a distance of 10m
It can't be further away of 20m, as, at least in one shoot, the shadow of the object is visible on the ground, making the object to be closer than the
stop sign, as shown by 'gguyx' above.
All of this is consistent with the hypothesis of a small metallic object thrown in the air between each shoot.
