Thanks for compiling all these statements about object height
relative to the moutains and the distance to the objects.

My guess is a few peaks just south of Rainier.

I think this is wrong.

No.

Perhaps. Or, since he didn't know where they were going,. he
may have figured they would pass by Adams or St. Helens (farther
to the west) and he could use whichever was convenient as
reference point.

Unless he looked up the altitudes of the mountains, how would he
know yes, he could have measured the altitudes with his
airplane, had he thought of it and dared to fly close to them).
As I pointed out in my analysis (not reproduced here), Arnold
said they appeared to be on his horizon...so he assumed they
were at his altitude. However, if they were 20 miles away, as
Arnold thought, they could have been 4000 ft lower and still be
"on his horizon", specifically, at a depression angle of only 2
degrees, so small it is lost in th "noise."

>If it's argued that this *couldn't* have directly affected his

It is so argued... because of his statement that they were going
in and out of the mountain peaks. He wouldn' t have to know the
altitudes of th peaks in order to observe that some were in
front of and others behind the objects (2 degree depression
angle, remember?)

>The Pendleton newspaper article also states, "The Boise flyer

More forest on the west side?

PELICANS
For Pelican Partisans Only:

Let's forget the claim of going in and out of the mountains for
the moment and simply concentrate on the directions to the
objects (a) when first seen, (b) when passing Mt. Rainier, (c)
when in the direction of Mt. Adams.

Assume Arnold was close to Mineral, Washington, about 25 miles
radially from Rainier; more specifically, 23 miles west and 10
miles south of Rainier.

OK, get yourself some graph paper with 1" squares (or larger)
and let 1" = a mile (or some other convenient square size on the
graph paper).

At the left side of the paper near the middle place a point.
That is Arnold's starting position. Let north be "up" on the
graph paper. Draw a line from Arnold's starting position at a
azimith of 15 degrees. This is approximately the direction to
Mt. Baker.

Draw another line with azimuth 23 degrees. This is the direction
to Mt. Rainier (about 25 miles away..... it will not appear on
your graph paper unless you have BIG paper or squares smaller
than 1"). Draw another line at azimuth 95 deg. This is Arnold's
track toward Yakima. Draw a final line at azimuth 136 deg. This
is the direction to Mt. Adams over 50 miles away. Now let's
construct a diagram of ARNOLD vs the PELICANS.

The bird explanation was discussed at length last fall (Nov. and
Dec) and then it dropped out of sight. Although I attempted a
reconstruction such as presented here way back then, I was
missing a key piece of data about PELICANS.... a piece which has
now been supplied by Mr. Easton (I believe he could have
supplied it last fall, but didn't). We knew back than that
Pelicans could achieve a top speed of 50 mph (more likely to be
20-30, however). What we know now is that the upper limit of
altitude as suggested by the ornithologists and glider pilots is
6,000 ft (more likely under 3,000). So let's characterize
Pelicans this way: wingspan - 10 ft length - 3 ft (? a bit
much?) TOP speed - 50 mph or 0.83 miles/min or 73 ft/sec TOP
altitude - 6,000 ft. Flight Direction: 170 azimuth (could be 180
or 160...won't make much difference to this disaster)

Let us charactersize Arnold by altitude - 9,200 ft speed - 100
mph or 1.67 mi/min or 147 ft/sec

Note that this estimate of Arnold's speed is probably low. We
also characterize this reconstruction by the overall time of the
observation. arnold said 2.5 - 3 minutes. Let's pick 2.5 (as
being advantageous to the P hypothesis) In that time birds fly
2.5 x .83 = 2.1 miles In that time Arnold flies 4.2 mi

Now go to your finely executed graph paper with the radial lines
emanating from Arnold's starting position and follow me. Mark 2
miles along the 15 deg azimuth radial. This is the assumed
initial distance of the pelicans. At this distance they would
appear as dots against the sky...or mountainous background
(Ignore observation by of arnold about metallic-like bright
flashes).

What do we find at the START of the sighting?

-angular size (birds seen nearly head on, flying south) , 2
miles horizontally, 3200 ft down, radial distance = 2.1 miles,
angular size = arctan (10 ft/2.1 miles) = 0.9 mr = 0.052 degrees
(mr = milliradians).... detectable -depression angle is
arctan([9200-6000]/2x5280} = 17 degrees (not exactly "on the
horizon"; 17 degrees down should be noticeable, whereas 2
degrees would be "lost in the noise." Therefore ignore arnold's
claim about the objects being on his horizon....)

Now draw a line from this initial bird position along the 170
azimuth direction. Make the line 2.1 miles long, the distance
the birds flew during the sighting and see where it ends.

Amusing.

On my diagram it ends right on Arnold's path. But by this time
Arnold would be 4.2 miles along his path, about 0.8 miles from
where he started, and the pelicans would be about 3 miles behind
him. This means that at all times they would have been to his
left and the sighting line to them would rotate to the left and
behind.

Please keep in mind that this is a DYNAMIC situation: Arnold and
the pelicans are moving. If one is clever one can find a point
of closest approach by marking off time intervals and measuring
the distance between th plane and birds at the various interval
positions. Try 15 second intervals.. At APPROXIMATELY 45 seconds
after the start.Arnold has already crossed the path of the
oncoming pelicans but they are still about 1.5 miles north of
his track. Arnold would be looking back to his left at about 25
degrees west of north or 120 to the left of his heading
direction. The depression angle at this time would be about 22
degrees, considerably below the horizon. The angular size would
be about 50% greater than the initial value ... probably wings
would be distinguished.

At any rate, one can hardly imagine Arnold describing this
situation as saying that the "saucers" flew down the hogback
chain of mountains toward Mt. Adams. So, to solve this problem,
ignore arnold's claim that the objects flew over the mountains
south of Rainier and ignore his claim that they were last seen
in the direction of Mt. Adams... Now you can accept the
Pelicans. Right?

If Arnold turned his plane under these circumstances it would
have been a turn to the left and he would have been flying
northward, opposite to their direction.

Now, as alternatives one could assume various initial distances
of the pelicans from Arnold's starting position, e.g., instead
of 2 miles along the 15 degree azimuth direction, try 1 mile, or
1/2 mile. go ahead. Try it. See what you get.

OR, try something more "realistic." Assume Arnold was wrong in
saying he first saw the objects north of Rainier. Ignore this
observation of arnold. Instead, assume he first saw them in the
direction of Rainier. So, mark off 2 miles along the 63 degree
azimuth.

Now mark 15 second intervals of 0.21 miles along the 170 degree
azimuth flight path southward of the pelicans. Also mark 15
second intervals of 0.42 miles along Arnold's path. You will
find, oddly enough, that the flight paths nearly cross in 5
intervals, i.e., 1 min, 15 seconds. Arnold has gone 2.1 miles
and the birds have gone 1.04 miles from their respective
starting points. At this time the pelicans are roughly 0.1 miles
= 528 ft north of Arnold and at an angle of about 105 deg to the
left of his heading. The radial distance is now (528^2 +
3,200^2)^0.5 = 3243 ft. The angular size of 10 ft wingspan is 3
milliradians... easy to resolve wings. The depression angle is
arctan (3200/528) = 81 degrees. Arnold is looking almost
straight down at the birds. After this the birds would b behind
Arnold, and below.

Ignore arnold's claim that the he saw the objects in the
direction of the chain of mountains south of Rainier AND ignore
his claim that he last saw them in the direction of Mt. Adams.
After proper ignoring, pelicans are definitely in the running.

One can, of course, play with the resconstruction a bit. If the
initial pelican distance is pushed farther away the pelicans
stay to north of Arnold's flight path during most or all of the
sighting. This decreases the depression angles somewhat, but
never do the pelicans appear to be south of Mt. Rainier

If the initial pelican distance is decreased, to say 1 mile,
then Arnold passes their flight track in about 30 seconds, about
15 seconds ahead of them. The depression angles are large all
the time.

Anyway, I invite Pelican Partisans to invent their own
reconstructions and prove that the objects could have been
pelicans. Please be specific as to which of Arnold's sighting
details we no longer need to accept as accurate in order to
accept the pelican hypothesis as accurate.
