 We are in the grips of
an unusual phenomenon.
All over the world, people have
been seeing giant triangles.
The most famous, Belgium, 1989.
Phoenix, Arizona, 1997.
Tinley Park, Illinois, 2004.
All of them at night.
But now new breaks in the
investigation of these
unexplained triangular craft--
we've uncovered
rare, never before
seen daytime footage taken
in an area of California
known as Triangle Alley.
 They're massive.
They're flying so slowly
over us that if it
were a conventional aircraft,
they'd fall out of the sky.
 So we're going to talk to
Mark and Jed, two sky watchers
here in Sonora,
California, who've
had some credible
daytime and nighttime
sightings of flying triangles.
 It was June 15, 2004, when I
was here on that balcony right
there with you.
We were looking at
the sky up there,
and you videotaped a real
triangle during daylight hours.
MARK OLSON: Oh, my god,
I've got three lights
in a triangular formation.
 Are you sure?
MARK OLSON: Yes, this
is-- this is-- this is--
oh, my god.
 I was right there next to him.
And I was-- you know, I was
fumbling with my camera,
but by the time I
got everything up
and running, this
thing was gone.
 You missed it.
 I missed it, unfortunately.
But Mark was there.
And I'm telling you guys,
this really happened.
 And these lights,
they were equidistant,
and it seemed like it was
from one solid figure.
 Yes.
And they didn't vary as
they moved across the sky.
They stayed fixed.
MARK OLSON: What
the hell is that?
 Are you sure?
MARK OLSON: It's
behind those branches.
You didn't see it?
Oh, my god.
 These UFOs originated
back behind this ridge.
Are you aware of any Air Force
bases, maybe just an airport?
 Over on the other side of
this ridge is Columbia Airport.
It's a very small airport.
They don't even have radar.
 What about military?
 The only a military base
is Castle over in Merced,
and it's closed.
 Well, people might be
tempted to ask, why is it
that you both see so many UFOs?
 I've watched for
literally, thousands of hours
for a few minutes of footage.
 This is more
than just a hobby?
 Oh, for a while there, it
became an obsession, almost.
Just wanting to
know what they are.
 Sounds like it paid off.
 Sort of.
Yeah, I want to know--
I still don't know
what they are.
I still want to find out.
 But we have daytime footage.
That's just so incredibly rare.
 I hope it can be
analyzed independently.
And so we can see
what these are.
 The Mark Olson video is
really interesting, not just
for what it is,
but because it's so
reminiscent of the video
shot in Belgium in 1989.
Both the Olson video
and the Belgium video
were three lights in a
triangular formation.
But the Belgium video was even
more compelling than the Olson
video because the
Belgium video actually
showed a physical object holding
the three lights in place--
a triangle.
I believe that if Terrence
Masson has a chance to analyze
this Mark Olson video,
what he's going to see
is an object holding the
three lights together.
That's our next stop--
Terrence Masson's lab.
KEVIN COOK: Terrence
Masson is an image analyst,
and he'll be using
motion tracking software
to isolate and stabilize
the three lights in Mark
Olson's daytime footage.
We're going to analyze
Mark's video frame
by frame to get some answers.
 So what I've done here.
First is cropped out the
majority of the frames
we can concentrate on the
object itself and stabilize it
We can tell definitively
here, these things
are rock solid information.
This is a good solid
4 and 1/2 seconds.
And even the tightest
precision acrobatic flying,
you're going to see some
kind of relative motion
over that kind of time frame.
 Can we eliminate
the obvious things?
Is this some type of helicopter?
Is there any evidence of that?
 Well, without
having 100% certainty,
I can come up with a
long list of things
that make this not anything
like conventional aircraft.
Going away from the
running footage now,
we've got single
still frames isolated.
And I've run some image
processing routines on this.
And look at what's coming.
We see some clear
indication of a structure
behind in between
those three lights.
 Whoa.
 And black triangle?
I mean, there's clearly
something there.
 Is there any other
explanation that the darkness
around these lights is something
other than a solid object?
 Many times we've seen in
these consumer grade camcorders,
the exposure range
for the pixels
that capture this information
are very, very limited.
And sometimes we do
get blooming effects.
So next to very bright
lights, it'll tend
to compensate and go very dark.
That's not what
we're seeing here.
It's too consistent over
too long of footage.
 What's your best guess?
What are we looking at?
 My best guess would be we're
looking at a single triangular
shaped dark craft with three
very large either propulsion
or illuminating
lights that's not
consistent with
any manmade craft.
