Travis AFB, CA August 30, 2008
"The horn on the front of the airplane is a horn that goes off when you are about to exceed nosewheel steering limits while towing. It actually went off when they were towing her at Travis."
No microprocessors, no digital displays, no LCD screens. Analog electromech tech at its zenith. I love this cockpit. No software, not one BIT.
Pilots overhead panel shot. No touch screens or software driven controls here. Real toggle switches, potentiometers, rheostats, cable linked valve controls and incandescent bulbs. Those flip-up toggle switch guards probably saved more than a few crewmen from making a mistake. You had to think twice before you could flip a critical switch.
Circuit breaker panel. Lots of 28 volt DC power on a C 133 and 200 VAC 400 hz 3 phase power as well. There was also 115 VAC single phase 400 hz power for avionics and doubtless some transformer or inverter supplied 26 VAC 400 hz here and there for instrument gyros, selsyns etc. I would have loved to have Ski's in flight job, but not the knuckle busting wrenching he had to do for years out in the open to keep this old girl airworthy. No heated hangers, no giant USAF maintenance and logistics organization backing him up, no manufacturers tech reps helping him to troubleshoot problems. Just Ski and his colleagues performing a labor of love. That they were able to keep this plane flying more than 40 years after the USAF sent her to the boneyard as timed out and worn out is nothing short of incredible. You gotta take your hat off to these miracle workers. I sure do!
Above: further circuit breaker panel detail.
Below: Cavernous C 133 fuselage designed to carry ICBMs. As a longtime skydiver, all I could think about was the opportunity we missed to have 500 jumpers exit from a single aircraft.
Ferry permit for final flight to Travis AFB
Would you have flown pressurized with a cracked windshield pane like this? I am guessing that the crack on this multi-layer pane isn't as dangerous as it appears. The flight tracker website shows that N199AB was at 21,000 ft and making 240 kts on the flight from McChord to Travis. One person said that the crack occurred in flight during the leg from AK to WA. This is probably correct since the FAA ferry permit did not require unpressurized flight.

Note cracked windscreen this time shot from the inside. Unlike most planes on their final ferry flight which have many non essential systems and instruments inoperative, N 199AB flew high and proud with all major systems fully operational and boasting a current IFR certification. Ken "Ski" Kozlowski, the crew chief and FE, took very good care of this old girl.
Ski's flight engineer panel. Note the vibration sensor indicator panel in the upper left. In a C 133, there was always a "whole lotta shakin goin on." If you double click on this picture it will expand. If you do this, you will then note a tiny + sign that can be moved with your mouse. Position it over something of interest and double click. This will allow you to see high detail on a selected portion of the image. Let me know if it works. My email address is at the very bottom.
The notorious Curtis Wright props. Endless trouble for the USAF but somehow "Ski" kept em running true. His secret? A custom made gauge given to him by a former N199AB pilot who Ski referred to as a genius on all things Cargomaster. This gauge allowed very precise spacing between a prop gear and a speed sensor coil that picked up pulses from the passing gear teeth. If that spacing was set properly, a lot of prop control and synching problems were avoided. Ski's "sweet spot" in the sensor-to-gear spacing dimensions was actually different than specified in the USAF TO manuals. Interestingly, Ski said the Garrett APUs, not the engines or props, were the biggest maintenance problems. Take off was always done with both APUs running but Ski usually shut down one once they were aloft. He wanted to be sure he had one in reserve that could get them home.
Another engine photo.
These engines seem small for being capable of delivering 6500 HP. The black and yellow areas sported fresh paint. This proud old girl put on makeup for her star appearance at the Travis airshow.
C 133 navigator's station. Jurassic era. Note non FAA approved ancient Texas Instruments marine Loran C receiver in white plastic case on the left. These barely fetch $10 on eBay these days. No fancy Garmin IFR certified color GPS map gear here. The white faced CRT instrument to the right of the orange weather radar display is an ancient (APN ?) radio altimeter.
C 133 navigators were not GPS moving map readers, they were the real deal using sextants to shoot stars, doing pressure pattern nav, lining up master and slave station pips on old Loran A sets and converting master slave delays (measured in microseconds) into hyperbolic lines of position.
Above left: Bulbous nose radome housed the weather radar antenna. N199AB appeared to still have the original USAF radar, believed to be an APN 59.
Above center: The last logbook entry is very poignant: " To the boys at Travis, Keep this old girl in good shape. She has been a great aircraft." Reading it choked me up, really.
LEFT: Typical logbook maintenance entries. Would anyone like to see more of these? I shot almost the whole logbook.
RIGHT:Nose gear well. Note loudspeaker and horn. Did C 133s honk? I'd actually like an answer to this question? My email address is at the end of this website.
My girlfriend Sara, relaxing in the cool shadow of N199AB's huge starboard wing. Sara is not a propliner nut like me, but she is a very good sport about my various aerial addictions. Sara is on the mathematics faculty at a California college. She has a passion for math that rivals mine for aviation. UPDATE: After ten years I finally popped the big question and Sara said yes. We were married in August of 2010.
Little boy, big plane. Note the retrofitted fuselage hoop bands. Douglas made this post production mod to reinforce the C 133 fuselage skins which were prone to stress cracking. Some C 133s suffered catastrophic in flight structural failure caused by rapidly propagating skin cracks.

Below: Logbook entry showing crack in pilots eyebrow window on TO from ANC in 1989 and noting 1/2 psi limit on cabin differential pressure. Pane was later replaced. Another entry shows elevated GPU oil temp, solved by replacing a collapsed air duct. Another entry shows replacement of a defective turn and bank indicator on the pilot's panel. There is always something to fix on a C 133 or any vintage aircraft of similar complexity.

Above: Flight Engineers vibration sensor selector and readout panel. What if the C 133 had been better designed so that it had no abnormal vibration problems. Would they have stayed in the USAF inventory as long as C 130s of similar vintage?
Above: Collins 618T HF SSB radio transceiver. This radio was the C 133's only link to civilization on overseas flights when beyond VHF range. Comms over distances of several thousand miles were possible when ionospheric conditions were optimal. Since the Earth's ionospheric conditions are highly dependent on solar weather (sunspot activity), C 133s on long overwater trips could be completely out of radio contact for hours if there were no sunspots. Pretty spooky if you are flying a plane plagued by structural problems and unexplained crashes. Today, C 17s and C 5s have satellite comm gear that assures constant contact with land bases.
Massive C 133 cargo winch with levelwind mechanism and fairlead.Runs on a BIG 28 volt DC motor. Could function on 12 volts at reduced power/RPM. Just right for the front bumper of your monster truck!
Surprisingly, this monster winch is still in use in the USAF in 2008! I reprint an interesting email below from a USAF loadmaster, CMSgt Thomas Dzwonkus (Ret) who wrote:
"Great stuff. I just retired as a loadmaster on 16 Jul 2008. I flew on
C-124's, C-130's and C-5's for a total of 37 years and 12,500 flight hours.
A little info for you, that big cargo winch is still used on the C-5 for
specialzed loads. I winched a 212000 pound trailer into the C-5 using this
old but powerful tool as recent as last year. They work awesome and most of us
wish that there were more of those available as there are only about 20 left in
It was tough to leave the loadmaster career field due to the fact that you had
to use your brains to figure a solution to load some of the odd stuff into metal
Again, enjoyed the pictures, maybe they will let you into the C-124 to
photogragh that old beast, some interesting stuff in there including an
elevator and an awesome flight engineer panel."
Can you tell I like aircraft systems and not just exterior airframe shots? Thought so. Well, everyone shoots the airframe. Someone has to shoot the systems. That someone is me.
The real truth? Well... who can compete with Ruud Leeuw a far as airplane pictures are concerned? Check this out:
I have very little competition in photographing various systems components such as prop synchronizing servo amps, cargo winches and HF SSB radio transceivers. Aviation author and Lockheed Constellation history expert (I think he even has a type rating) Ralph "Connieman" Pettersen spied my pitiful point and shoot digital camera at Travis and quipped good naturedly: " Mark... when are you going to get a REAL camera?" Hey, at least if it gets stolen I will not have to get a Prozac prescription. You could probably buy a decent used Cessna for what Ralph's cameras cost. Mine would buy about 15 gallons of avgas.
Collins 618M VHF AM transceivers. I think these are vacuum tube radios! Double click to enlarge and then double click again to see detail of all the complex autopilot system components above. There must be 1000 lbs of Cannon plugs on a C 133.
ARN 21 TACAN nav gear. Distance measuring equipment.
White box on celing house a liferaft which deploys through the top of the fuselage. Click to enlarge and look at the maze of wiring harnesses that criss cross the fuselage interior. Must be hundreds of miles of wire weighing several thousand pounds in this bird. Every single wire is thoroughly documented in the C 133 TOs (tech orders, thick manuals).
Nose gear well detail.
Above: Fuselage hoop band detail. Wonder how much drag was added? The dark vertical strips appear to be some kind of caulking or sealant applied to a lap joint between portions of two bands and fuselage skin. Note that the band stops above and below the windows probably relying on the interior window framing to supply the needed crack protection reinforcement. Click on the photo to enlarge and note the huge overlapped skin patch that is on the upper fuselage exterior and under the hoop bands. This once sleek flush riveted fuselage surface now sports a lot of draggy lap joints which must have cost a couple of knots in speed. Well worth the speed penalty, of course, if it prevented skin cracks and catastrophic explosive decompression.
Below: there were many former C 133 crew milling about N199AB after its arrival, trading stories and reliving memories. Their consensus was that the ominous black stain below (an identical mirror image stain was on the port side as well) was that it was not a hydraulic fluid or fuel leak artifact, but rather a rainwater caused stain and no big deal at all. It was great talking with so many folks who flew, crewed and wrenched on the C 133. They came from all over the US to see N199AB's final moments of flight and arrival. Despite the checkered safety history of the C 133, to a man, they would all fly in one again given the chance.
Spare engine on special trailer.
Pratt & Whitney T34-P-7WA
Fairly small engine for the amount of power it produced, 6500 HP! Later versions on the C 133B added 500 HP. Despite those impressive specs, the C 133 was considered by many to be a bit underpowered.

End of a long journey, from USAF boneyard, to decades of rugged Alaskan civil flying, to a well earned USAF base museum retirement.
Full circle for an Unsung Giant!
What you see here just scratches the surface. Cal Taylor has authored a truly great book about the C 133 which is meticulously researched, full of photos and covers civil as well as military history of this plane. Details are on his website.
