Ted, I appreciate your comment. However, you should be clear on
the observing conditions.

It was night, the aircraft were over terrain covered with normal
architectural lighting, and the object may have subtended .3 degree.

Of that .3 degree, we have significant testimony that the objects
are not completely luminous, but that only the tips of the
triangles (or the objects at the corners of the formation,
depending on which sightings we're discussing) are luminous. If
we use the Petit-Rochain photo as the prototype, then each
discrete light source is probably no more than 1/4 of the size of
the object, and possibly less.

Thus, the size of an individual light would be no more than 50'
(and possibly smaller), thus having an angular size of roughly
0.075 degree.

I am willing to believe that even the acute vision of a pilot
might have some trouble with discriminating this. It is also
important to note that the pilot is primarily focusing on the HUD
during an intercept, and while a pilot will certainly appreciate
visual contact during a night intercept, he is in fact relying
almost entirely on instruments.

In addition, the HUD itself presents a variety of symbology which
is directly centered on the radar track. This symbology could
also obscure any visual contact.

Note also the weather conditions are "visibility 8-15 km" which is
4-9 mi.

Perhaps Henny can help us out with information that will also be
useful with regard to how long the pilots were in dark conditions
prior to the radar lock on. According to Haines [1980], the human
visual system requires about 20 minutes for complete dark
adaptation. In addition, Haines points out that in the period
between 15 and thirty minutes of dark adaptation, human visual
sensitivity increases 60,000 times. According to Sheffield [1996]
the intercept was launched at 0:05, and the first lock on was 8
minutes later. Even assuming a 10 minute period in the aircraft
on the ground during the scramble, this is only 18 mins for dark
adaptation.

But Ted, that is not the situation. In the case being considered,
the pea is luminous, and randomly rolling around a garden filled
with other luminous vegetables. And you are looking for the pea
through a panel with luminous lines and symbols that are moving
and changing, and, in fact, you are doing this while flying above
the garden in a helicopter.

That makes it a little tougher, doesn't it? :-)
