inflight view of EC-121R 67-21490.
Photo is U. S. Air Force photo KE 35179, taken January 15, 1969, by
Master Sergeant Roman G. Contos, USAF. Labled as a "High angle side
view of U.S. Air Force EC-121 of the 553rd Reconnaissance Squadron in flight
of Thailand." I believe this is the best inflight view of a
Lockheed EC-121R I have seen yet. Size is set to be about full
screen with resolution set to 1024x768. Here is another image of
67-21490 at higher resolution, inflight with more of the Thai

The Lockheed EC-121R Super
aircraft flown by the 553rd Recon Wing were originally built for
the U.S. Navy by Lockheed as WV-2 and WV-3 Early Warning
aircraft. Begining in late 1966 Lockheed Aircraft Services
modified 30 ex Navy Super Constellations (2 EC-121P/WV-3 and then
28 EC-121K/WV-2) aircraft for the specialized reconnaissance
mission flown by the 553rd. These aircraft were issued new Air
Force serial numbers from 67-21471 through 67-21500. Conversion
work was completed by mid to late 1967. Here is a text article
with details of
the Lockheed EC-121R, including Lockheed construction number,
Navy Bureau number, USAF serial number, and disposition of the
aircraft. Also included are details of the C-121G aircraft loaned
by the Pennsylvania ANG to the 553rd, the YQU-22A and QU-22B
aircraft flown by Detachment 1 of the 553rd Reconnaissance Wing
at Nakhon Phanom RTAFB. You can also access this text file from
the main Batcat page. Updated
WV-2 to USAF EC-121R
EC-121R aircraft were all conversions of previously existing U.S.
Navy WV-2 or WV-3 early warning aircraft. Here is the starting

Transformation Involved changing the
interior and adding antennas for the mission
From a declassified CHECO report are these illustrations of the
Antenna system. This illustration shows many, not all of the anetennas. For
example a close look at other images on this page reveals a whip antenna at the
top of each outside vertical stabilizer. These whip antennas on the vertical
stabilizers were for the FM radios used to communicate with ground forces.

Most of the time the data picked up by the Batcat EC-121R was either relayed to
Task Force Alpha at Nakhon Phanom, or plotted on board by the CIM/ACICO/CICO then
the target data radioed to the appropriate unit to counter the detected threat.
As the effectiveness of the system became apparent, other U.S. military, Army and
Marines, developed equipment of their own. One such piece of equipment was the
"Deployable Automatic Relay Terminal" or DART. Batcat EC-121R aircraft
picked up the sensor data and sent it to the DART. This is a basic illustraion of the
working with a DART. B&W, about 139K. My thanks to
Les "Robbie" Robbins

Lockheed Air Services Performed
the Transformation modifications
Col. Ostendorf told me that the USAF put
out to bid the conversion of the Navy WV-2's to EC-121R
configuration. Because of their familiarity with the Super
Constellation, Lockheed won the conversion bid.
Mike Wingate was a radio and radar
technician who worked for Lockheed Air Services, LAS, who
performed the actual work at their Ontario, California facility.

Emergency "The Da Nang
On June 4, 1969 an unique incident occurred
with a 553rd Reconnaissance Wing EC-121R. Shortly after arriving
on station, with the crew and airplane settling in for the work
which needed to be accomplished, everyone was suddenly startled
by the silence. Read about how All 4 Propellers
Feathered Inflight!!. Adobe PDF format, about 113K. Officially around Korat
this airplane came to be called "The Da Nang Glider."
As far as I can determine, never before, or after, has a Lockheed Constellation
or Super Constellation ever had all four propellers feather simultaneously

As you might imagine 553rd Reconnaissance Wing aircrews felt some concern flying in an airplane
which had all 4 engines shutdown and the propellers feather inflight. By the end of September 1969
EC-121R serial number 67-21487 was ready to return to service and fly combat missions. To reassure
the aircrews 553rd Maintenance circulated a
Operations Newsletter from the Deputy Commander for Safety in September 1969. This newsletter
described the event, what maintenance had accomplished to make certain the problem was resolved.
This newsletter describes all the parts which were replaced, and what changes occurred on each of
8 test flights of 30 hours before returning to service. My thanks to Dave Hall via

Need Help to
Identify the 553rd Maintenance Technicians
who went to Da Nang to service the "Da Nang Glider"
As soon as the "Da Nang Glider" landed safely at Da Nang,
the 553rd Reconnaissance Wing sent maintenance technicians to Da Nang, South Vietnam to
trouble shoot, and repair the EC-121R. As far as I can determine the immediate, critical
need for qualified EC-121 maintenance technicians meant that only verbal orders were
issued to those from the 553rd EMS (553rd AMS), 553rd FMS and 553rd OMS squadrons to go to Da Nang,
South Vietnam. Some of the maintenance technicians now have health issues which herbicides/Agent Orange
expossure may have caused. Because there were verbal orders only, proving "boots
on the ground in Vietnam" to the VA, and therefore "presumption of exposure," is very difficult.
The VA needs substantiating corroboration from others so these maintenance technicians who
went to Vietnam can get approval for herbicide/Agent Orange exposure health issues.
Linda Donley, wife of Batcat Ron Donley, 553rd FMS, who passed away 01/23/11, would like to hear
from anyone who knew Ron Donley. Ron Donley was part of the group from the FMS
squadron who was sent to Da Nang, South Vietnam in June 1969 to trouble shoot and repair
the "Da Nang Glider" incident. Hopefully a substantiated list of all those who serviced the
"Da Nang Glider" at Da Nang, South Vietnam can be established. If you can help please

June 3, 1969. This view shows what remains of the airplane
after removal from the crash site, as it sits on a stack of wood,
with a B-1 maintenance stand near the rear entrance door. I believe
this airplane was used only as a source of spare parts after the
landing accident. Color, about 13K. Added
67-21493 April 25, 1969
Second aircraft lost was 67-21493 on April 25, 1969, at Korat.
All 18 Batcat aircrewmem were lost in this crash. I obtained the
"releaseable" parts of the full accident report. I make
available here the Accident
Summary of the loss of BATCAT 21 on April 25, 1969. I retyped
the information and present it in ASCII text format. I obtained
the report through the Feedom of Information Act. My Thanks to
A. J. Northrup, author
of "Fifty Fallen Stars," for information about how to
obtain documents through the Freedom of Information Act.
I obtained these images which show the crash of Batcat 21,
aircraft 67-21493, on April 25, 1969. These photographs were
taken the day after the crash. Image
21493-2.jpg shows an overview of the crash site. Image
21493-1.jpg is a closer view. Batcat 21 departed Korat at
1600. I was a crewmember on the next Batcat take off at 1645. I
have a vivid memory of looking down shortly after take off and
seeing the remains of Batcat 21. The only piece of wreckage I
could identify from the air was the triple tail of the Lockheed
Super Constellation. Image
21493-3.jpg is a ground view of the wreckage. These images
were included in the accident report, however the quality in the
accident report is very poor. These are much better quality
images added 08/19/07.
Jim Bost sent me
another view of the crash of
67-21493. This is probably the best quality image of this
loss. B&W about 206K. Added
After the crash the wreckage of 67-21493 was moved back to the
Korat dump. Here are views of the wreckage. Dump view 1 shows
part of the Triple
Vertical Stabilizer. Dump view 2 shows a Landing
gear and engines plus other parts. Both ar color, about 216K
and 188K respectively. My thanks to
Danny L. Hildebrand who was part
of the 388th CES (Civil Engineering Squadron) who sent me these
images. Added 02/12/14.

Four photographs of the third Batcat aircraft lost, 67-21495, on
Sept. 6, 1969 while trying to land at Korat in a very bad rain
storm. Taken from the road going into the city of Korat the day
after the aircraft crashed, image 1 shows a ground view
of the crash, B&W, about 25K. Second image of the crash
is an aerial view
of the crash. B&W, about 66K. My thanks to Randy Spencer for providing this
aerial view, of the EC121R loss. Dave
Smith sent me several views of the crash. Dave has
a very personal interest since he was aboard the aircraft. After
recovering Dave met an airman from the base photo lab who loaned
him several views of the crash taken from a helicopter. The third
crash view shown here is a direct
overhead view of the crash. Added
10/28/00, about 66K. Four Batcat aircrewmem and 4
Thai's lost their lives in this crash. Another view of
67-21495 taken from a 2 baht bus. My thanks to

Dave Shipton provided
mouth EC-121R image. When the 553rd Reconnaissance Wing
deactivated in December 1970, there was a turnover ceremony. This
shark mouth painted Connie was the EC-121R which flew in the
airshow at Korat for the turnover from 553rd to the 388th. The
flight crew was, if I recall correctly, Lt. Col Given, Commander
of the 553rd Recon Squadron, Maj. Wilson, MSgt. Dave Shipton and

TheBeech QU-22Baby Bat replacement for the EC-121R
an effort to reduce cost, the Air Force tried to replace the
EC-121R with a highly modified Beech Debonair, the YQU-22A.
During 1969 the YQU-22A was evaluated by the 553rd Reconnaissance
Wing Detachment 1 at Nakhom Phanom (NKP). This evaluation was
known as Pave Eagle I.
These YQU-22A aircraft would occassionally visit Korat.
Evaluation determined the Beech Debonair was too small and
underpowered to perform the job. Here is a text article with
of the fate of each Beech YQU-22A and QU-22B aircraft.
Once the 553rd Reconnaissance Wing was inactivated in December 1970,
the 554th Reconnaissance Squadron number was assigned to the QU-22
operation at Nakhon Phanom RTAFB (previous this unit was detachment 1
of the 553rd Reconnaissance Wing). Upon arrival pilots were required
to complete in-processing and a local checkout. This is the
In-Coming processing and local check out check list items which needed
to be completed. My thanks to Ken
Clagett for this in-processing check list. PDF format, about 90K.

68-10533. This airplane flew missions from NKP,
had a landing gear collapse on April 8, 1969, was returned to the
U.S. and repaired. Sold to a civilian owner and on the FAA
register as N52242. Photo by Alan

My thanks to Brian
Studer for this photo. Color, about 323K.
To have a larger airplane with more power, the USAF began using a
modified Beech Bonanza model 36 identified as the QU-22B. The
back seat was removed and sensor receivers were installed. There
was a position for the pilot, but ideally they were to be flown
without a pilot. Some 27 "B" models were built. The
QU-22's became operational, but were always flown with a
pilot on operational missions, not flown as a drone as originally
invisioned. 553rd Reconnaissance Wing Detachment 1 at Nakhom
Phanom again performed the evaluation with a project name of
Pave Eagle II.

Randy Spencer sent me
some QU-22B photographs, including this photograph of a Beech QU-22B
Fuselage, which were taken during April 2002 at Lake
Elsinore, California. Here is a photograph of the Beech QU-22B
Cockpit. Cockpit is pretty standard Beech model 36 Bonanza,
however notice on the right side there appears to be a frequency
meter (old reed style), a "G" meter, UHF communications
rather than VHF. Dual VHF omni and an ARC ADF-21. Both
photographs are the same airplane, serial number 69-7701. Viewing
Randy's photographs reveal the airplane appears to be intact,
although disassembled, and the aluminum appears corrosion free.
Reports are that enough parts are available at Lake Elsinore to
build up 3 complete QU-22B aircraft. Both images are color, each
about 72K, added
