Altitude and speed remained same throughout course.

2. Pronto Blue (1 AT aircraft) scrambled at 05282 hours and Pronto White
(1 AI aircraft) scrambled at 0508Z hours. Captain D. Jarrett (Pronto Blue)
and 1st Lt A. Young (Pronto White) both of 317th Fighter Interceptor Squadron
were Intercept Pilots. Pronto White had to abort due to radar trouble.

" SROPION IIT OTHER PERTINENT FACTORS

1. Im answer to query, Coast Guard vessels reported sea swells as moving |
on a course of 050° with swells 94 feet high having sharp breaking crests
moving in at 8 second intervals. Surface winds from North at } knots. No
visuals on unknowns by three Coast Guard vessels in area. Did see and hear jets.

no air activity in area. MST reported large vessel in area which was located
by radar. |

kh. Hoby Dick Pro eked for balloon activity.
One ball ased at Tillamook on Monday evening and moved to ND 5010

AcMe It hovered there at 55,000 feet for few hours 1 pressure
area switehed-and balloon moved in opposite direction to LA 5000 at

hours, 13 May 1953.
S. Wind was from NE at 5,000 feet, 20 knots.

6. A Coast Guard radio operator at Westport, Washington reported recei
CW transmissions on 500 kes that were very weak and unintelligible. Trans-
missions were intermittent lasting from 30 seconds to 1} minutes, beginning
just prior to 05002 hours and ending shartly after 060027 hours. They were also
heard by Department of Transport, Port Hardy Radio Range Station, Vancouver
Island. No bearing could be obtained due to weak signal. The FCC monitoring
station at Portland was queried as to receipt and reported negative; however,
they had been monitoring 500 kcs. The Coast Guard radio operator reported
that he thought that there were three different transmitters involved in the
signals he was receiving and that it sounded like they were using a technique
that can be utilised for homing to effect a rendezvous.

7. Major Deckert, Operations Officer of 317th Fighter Interceptor Squadron
was sent out in a B~-25 around 2300 hours PST. He searched within a 200 mile
radius for surface vessels capable of lawnching or carrying small aircraft.

All ships located were determined to be friendly. Visual surveillance was

accomplished on several ships after daybreak. On headings of 210° Major Deckert
received what is. considered to be sea return on radar. On reciprocal (030) he

received no pickup. On 210° he was flying directly into (against) the 94 feet
high swells. The swells were crested, tims forming a cup sufficient enough
to reflect the radar energy. On the reciprocal course the szircraft was flying
with the swells, the crests breaking away from him. This would appear to
explain that there would not be enough surface at proper angle to reflect the
radar energy.

8. There were numerous fishing boats in the area which were painted by
the AI interceptors, the B-25 and by PG.) “Ac +'~ |

SECTION IV DISCUSSION

1. A study of the alignment of plots provided by station P-57 on these
tracks and the report from personnel at the station that the blips looked
normal and did not resemble wave blips, leads one to conclude that these
were airborne objects. This conclusion can be further substantiated when
considering that the sea swell was ruming in a direction that would result
in a very shallow contact angle between the beamed energy and the face of the
swells in the vicinity of the wmiknowns. Therefore, little or no radar energy
would be reflected back to the receiving system of the ground station. This
conclusion is further substantiated by the results obtained from AI radar
when on certain headings during this time period.

2. Tha fact that station P-);); was wnable to pick up these tracks when
they were within the surveillance capability of their station refutes the
' gonelusion, to some extent, that these wers airborne objects. P-hl; had com-

pleted their weekly maintenance that morning and the set was painting friendly |
air traffic and numerous fishing boats and some ocean vessels. -

3. At oL0OZ ar sonde obs from Tatoosh Island (Meah |
Bay) reported a six emperatura inversion 1500 and 1700 fost

HSL. 3 fa accounts for P-l receiving strong returns on ships well
out to 56a. % research caltbration tests coritucted
at B57 by personnel from USAF, Research-Development Cormand and University of
. Texas, that unusual phenomena can and will occur during inversions which can
have varied results on radar energy. The energy may be reflected, null arsas
may develop and blips may appear on scopes when actually no airborne object is
present at that location. These specialists were wmable to provide proven
criteria, at that time, for practical application by the AC&W system. it is
noted that site P< was below the level of the existing inversion and that
if the inversion's altitude was 1500 to 1700 feet in the vicinity of P=57, that
site equipment was above the inversion. Such a condition may have developed a
nvll area for P-lkh at the Bogey's altitule or P-57 may have been receiving
energy reflected from a localised unusual atmospheric condition. Note Captain
Tate's comments (Inclosure #1) about target's actions at 2000 feet.

hh. The Westport Coast Guard station is located at LB 5253. The unknown
tracks were within 50 to 100 miles of this station during the time the radio
operator was receiving transmissions on 500 kes. Coast Guard Headquarters at
Seattle provided the ADCC information regarding these signals because of ADCC
controller's previous request for reports of visual sightings by Coast Guard
vessels known to be in vicinity of Track B-97. Portland FCC Monitor Station's
4nability to read signals on 500 kes could be attributed to weak signal strength.

SECTION ¥ CONCLUSION
1. This Neadquarters is wmable to further evaluate these tracks.
2. No firm conclusions can be reached as to identity of subject tracks.
