Both men had friends who had "seen flying saucers" at some time, but
both had openly voiced their skepticism. Now, from what the colonels
said when they were interviewed after landing at Colorado Springs,
they had changed their opinions.

Nobody knows what the two colonels saw over Carson Sink. However, it
is always possible to speculate. Maybe they just thought they were
close enough to the three objects to see them plainly. The objects
might have been three F-86's: maybe Flight Service lost the records.
It could be that the three F-86's had taken off to fly in the local
area of their base but had decided to do some illegal sight-seeing.
Flight Service would have no record of a flight like this. Maybe both
of the colonels had hallucinations.

There is a certain mathematical probability that any one of the
above speculative answers is correct--correct for this one case. If
you try this type of speculation on hundreds of sightings with
"unknown" answers, the probability that the speculative answers are
correct rapidly approaches zero.

Maybe the colonels actually did see what they thought they did, a
type of craft completely foreign to them.

Another good UFO report provides an incident in which there is
hardly room for any speculation of this type. The conclusion is more
simply, "Unknown," period.

On January 20, 1952, at seven-twenty in the evening, two master
sergeants, both intelligence specialists, were walking down a street
on the Fairchild Air Force Base, close to Spokane, Washington.
