CASE SUMMARY
1. The RB-47 case is the first known case of a UFO
transmitting its own radar beam (several other cases are now known but
the RB-47 was the first to become public). Not only was the UFO
tracked by an air defense radar on the ground near Dallas and by the
RB-47 spy plane's airborne radar, but the UFO itself was sending out
radar signals. It is the only known radar-visual-ELINT case on
record (a few radar-ELINT cases with no visual sightings, and a few
visual-ELINT cases, with no radar tracks, are known too).
2. The UFO's radar signals were picked up on special
highly classified Electronic Intelligence (ELINT pronounced "EL-int")
equipment aboard the RB-47. The RB-47 normally flew missions on
the periphery of the Soviet bloc, using its spy gear to locate enemy
radars. In this case, on July 17, 1957, the RB-47 flew out of
Forbes AFB, Kansas, on a training mission out over the Gulf of
Mexico. On its return leg, the UFO was detected on the spy
plane's ELINT gear.

3. It is ironic that the SETI project attempts to
detect radio signals from civilizations around distant stars many
light-years away from earth, and SETI scientists are very hostile and
dismissive of the UFO phenomenon. Yet here we have a UFO
transmitting radio signals from only 10 miles away from an RB-47 spy
plane. One would think SETI would be interested in this
very-close-to-home type of evidence.
4. The RB-47 case has been public knowledge since
1968. It was one of the late James McDonald's top cases he
investigated, which he presented as key scientific evidence for the UFO
to the AAAS (American Association for the Advancement of Science) in
1969 and the AIAA (American Institute for Aeronautics and Astronautics)
in 1971.
5. Although the Air Force's UFO project, Project Blue
Book, attempted to explain the RB-47 case, the parent organization of
Blue Book admitted it was a puzzling case. The ATIC (Air
Technical Intelligence Center) at Wright-Patterson AFB in Dayton, Ohio,
had its secret ELINT Branch analyze the RB-47 case. Their analyst
came back with the admission that "there is such a mass of evidence
which tends to all tie in together to indicate the presence of a
physical object or UFO" and that it is "difficult to conclude that
nothing was present, in the face of the visual and other data
presented."
6. The Condon Report in 1969 admitted that it could
not explain the RB-47 case, which its project at the University of
Colorado had uncovered in the first place, as part of its $1/2 million
contract study of UFO's for the US Air Force.
7. The late UFO skeptic Philip Klass made a powerful
and convincing case to explain the RB-47 incident, one of the most
thoroughly impressive skeptical UFO investigations ever
presented. But Klass' analysis was based on a number of egregious
and fatal errors. His flight path for the RB-47 was based on an
Air Force mistake that confused True and Magnetic compass
directions. As a result, in order to make his theory work, at
some points on his map of the RB-47's movements Klass had to have the
subsonic RB-47 jet travel supersonically, at twice the speed of sound
(supersonic Mach 2)!
8. When aerospace researcher Brad Sparks corrected the
RB-47's flight path in 1998, by uncovering the mistake about the True
vs. Magnetic compass headings, the entire case suddenly snapped into
place and made sense, and at the same this correction caused the utter
collapse and destruction of Klass' explanation scheme.
9. Sparks further discovered that Klass had attempted
to explain the visual UFO sightings by the RB-47 crew, of an intense
red light, as due to a nonexistent American Airlines flight supposedly
landing at Dallas airport at the time of the RB-47 UFO incident.
In fact, there was no such American Flight 966 at all, it was a
National Airlines Flight 966 and it was 600 miles away near El Paso,
and nowhere near Dallas-Ft Worth. The airliner's exact location
on that date is known because it was involved in an accident, with
passenger injuries, and airline and government records record the date,
time and exact location. It could not possibly have been seen by
the RB-47 crew from below the earth's horizon and from that 600-mile
distance.
10. The RB-47's ELINT system had Direction-Finding
ALA-6 equipment which displayed the compass directions of the radar
beams it received and analyzed. On overseas flights, these
Direction-Finding bearings or "cuts" as they were called, were used to
plot the locations of enemy ground radars on a map. The radars on
the ground do not move, of course, they are stationary.
11. What was startling to ELINT officer, Major Frank
McClure, on this RB-47 training flight was that he picked up a MOVING
radar signal which literally ran a ring around the 500 mph RB-47 while
they were over Mississippi. Later, while flying over East Texas,
McClure's ELINT scope showed that the UFO seen visually by the pilot
and copilot could also be tracked moving faster than the RB-47, still
traveling at about 500 mph. The RB-47 received signals not from
some motionless radar on the ground, but from an AIRBORNE radar in
rapid motion, and its location exactly matched the UFO's position.
12. At some points on the flight over Texas, the RB-47
detected BOTH the moving UFO's radar beam AND the unmoving Air Force
air defense ground radar near Dallas, SIMULTANEOUSLY. The two
radar beams came from different directions 30 degrees apart. When
Sparks corrected the compass errors made by Klass and the Air Force, it
became clear that the RB-47 had ACCURATELY plotted both the UFO and the
Dallas radar in the correct compass directions. Thus the ground
radar beam provided a scientific CALIBRATION of the accuracy of the
RB-47 gear in real time, an unprecedented event in UFO history.
This puts the RB-47 case at or near the top of the list of the
strongest scientific evidence for UFO reality on record.
13. The UFO's radar beam revealed the UFO was flying
faster than the RB-47 and moved "upscope" on the ELINT scope aboard the
RB-47 until the UFO was directly in front of the RB-47, as seen
visually and as shown on the ELINT scope. Whereas, the Dallas
radar was not moving so its directional bearings were properly
displayed as showing the RB-47's own motion, moving "downscope" due to
the RB-47's flight speed in flying past Dallas.
14. The RB-47's pilot Major (later Col.) Lewis Chase
went to maximum power to turn and pursue the UFO. After several
minutes, the UFO suddenly stopped in midair and the RB-47 overshot, and
flew over the motionless UFO (not directly over but at about 45 degrees
to one side). But at that same moment, the UFO "blinked out"
visually as if a light switch had been turned off, and it "blinked out"
on the RB-47's ELINT gear, and it "blinked out" on the RB-47's airborne
navigation radar which had been picking up the UFO too, for a short
time during the chase. Then after the RB-47 flew over, the UFO
"blinked on" again visually, on ELINT and on airborne radar, all three
"channels" of detection so to speak.
15. The Air Force AIr Defense Command radar at
Duncanville, near Dallas, also tracked the UFO and in the same position
relative to the RB-47 that the crew could see, at about 10 miles away
from the RB-47. The RB-47 was in direct radio contact with the
Dallas radar and compared position reports constantly.
16. After landing at home base, the RB-47 crew was
interrogated by intelligence officers at great length and their tapes
and records of the incident were taken away for study. No record
of what happened to the tapes was reported to Project Blue Book and the
crew never heard anything further about what might have been learned
about their incident or who might be studying it. Later
investigations by McDonald and the Colorado Project turned up nothing
further. However, it has now been discovered that the SAC
(Strategic AIr Command) ELINT Division at Omaha, Nebraska, obtained the
RB-47 tapes and records. The SAC analyst said the records package
was handled very unusually when it was turned over to him, it came in
as TOP SECRET when training flights like this one over the US normally
were only SECRET. Then after he sent in his analysis it
disappeared when he followed up, which he assumed meant it went into
compartmented secrecy and that he should ask no more questions.
