[From the screenplay] 
 
 
“The High and the Mighty”  
The aviation movie “The High and the Mighty” was released 
in 1954 and recently reissued in DVD format after extensive restoration of the 
original print. I saw it first-release after just attained two digits in age 
and, was entranced by the whole experience. My modeling experience of the time 
was limited to Strombecker, Aurora and Lindberg, but it was a good beginning. 
Later I was to discover the writings of Ernest K. Gann, author of the screenplay 
and the book from which it was derived.  
 
 
The Movie 
In this and other movies and books Gann folded in his 
experience as an airline pilot to craft perhaps the finest examples of their 
kind. “The High and the Mighty” in addition to being an excellent 
depiction of commercial aviation in the early ‘50s is now considered to be the 
first of the “disaster” movies.  
It was while Gann was working at Transocean 
that he wrote his novel “The High and the Mighty.” Inspired by several 
incidents that had occurred during the airline’s trans-Pacific operation, the 
storyline evolved into the tale of a routine airline flight suddenly and 
terrifyingly stricken with what appears to be a potentially catastrophic 
situation – a runaway prop and engine fire occurring at night halfway between 
Hawaii and the mainland.  
The actual flying scenes were filmed during the third 
week in November 1953 using a Douglas DC-4 borrowed from Transocean and piloted 
by Keating. The DC-4 was painted in the fictitious airline colors of the 
Trans-Orient Pacific Airlines …and filming was done at both San Francisco 
and Oakland airports, with some ground scenes shot at Burbank. The ending scene 
showing all the passengers and crew deplaning in San Francisco according to the 
pilot was actually filmed at the old and now-defunct Glendale Air Terminal east 
of Burbank, California, where a special outdoor movie set was constructed to 
replicate the terminal gates at SFO in those days. 
                                                                                                
[Shane, in Airpower]  
Actor Robert Stack who played Sullivan, Captain of 
Trans-Orient Pacific Airlines (“Topac”) flight 420 parodied his 
deadpan acting in this film in the later hilarious “disaster” movie send-up, 
“Airplane.” Director William Wellman and writer Gann were experienced 
aviators, a combination that ensured accuracy in the aviating portions of the 
film.  
 
 
The Airline  
The DC-4 “stars” of the movie are marked with the acronym 
of a fictitious airline, TOPAC but they are painted in the colors of 
Transocean Airlines, which loaned two of this type for the movie production. 
One of them, N4726V, is replicated for this article. Transocean 
was based in Oakland CA and did business from 1946-1962 back when round engines 
ruled the skies. It was basically a non-sked, but had interesting arrangements 
with first tier airlines from time to time.

Transocean DC-4. Ron Dupas: by permission  
Transocean eventually folded in 1962 (an interesting 
story in itself), but its founder Orvis M. Nelson started another firm, Air 
Systems, based in Cophenhagen that used surplus Douglas C-74 Globemasters
to ferry cattle and racehorses throughout Europe.  
But on the other hand, I like flying, and it would be 
interesting to see the reaction of the animals….We took the train to Gatwick, 
and I had my first view of our aircraft standing a few hundred yards away out on 
the airfield. It looked very smart, its red, white and silver-grey paint 
glittering in the sunshine. “Gosh, it’s big!” I said. Mr. Costain nodded. “Yes, 
it’s a Globemaster, and to the best of my knowledge it is the biggest 
aircraft in the world at the present time.” I don’t know whether he was right 
about this but it was easy to believe… 
                                    [James 
Herriot, “The Lord God Made Them All”] 
  
  
  
Four identifiable airplanes can be found in “The High and 
The Mighty.” The DC-4 of course is the “star,” accompanied by its faithful 
escort and partner, the United States Coast Guard PB-1G. Also seen are a C-46, 
and later a brief glimpse of a Coast Guard PBM. The first two, with more “film 
time” as it were, are presented in this article. 
 
DC-4  
After an abortive and overweight start the DC-4 was poised 
to take commercial aviation to a new plateau in 1941. Its design, Douglas or 
airline funded, was complete and a good engine had been found. The war 
intervened, and the rest is history. During the war the C-54/DC-4 made routine 
flight across oceans by landplanes. The fourth Douglas Commercial launched 
Douglas on its post-war dominance of the large Propliner market.   
There were so many cheap surplus C-54s around in 1945 that 
Douglas could only sell a few new copies of the design modified specifically for 
commercial use. Transocean had almost 70 of various surplus models on 
strength from time to time during its existence.  
The Douglas DC-4 was still in widespread use by major 
airlines in the ‘50s but soon would be eclipsed by the pressurized Lockheed 
Constellation and its Douglas successor, the DC-6.    
N4726V          This airplane had the usual diverse 
service of most of the war-built propliners. Before its time with Transocean 
during the years 1953-55, it had been the personal aircraft of Juan Peron and 
was operated by Slick Airways. Subsequently it was leased to probably a 
number of operators by Airwork and later operated by World Airways. 
It was to have at least one more operator. While with Transocean it was 
known as “The Argentine Queen.” 
 
PB-1G  
The USCG Flying Fortress plays a supporting role in the 
movie, but a fascinating one nonetheless. Clearly the Coast Guard took advantage 
of an opportunity to show case its SAR credentials, with additional appearances 
of a water-borne PBM and a crash boat complete with siren. We see a state-of-the 
art use of the “interceptor” B-17 first to locate, and then fly shotgun on the 
crippled airliner as it strives to make the coast.

PB-1G  #77255. USCG Photo 
Although we know a lot about the DC-4 used in the film, 
nothing is known about the PB-1G other than one is in the film, possibly via the 
use of stock footage. This in spite of the fact that the Coast Guard never 
operated more than 16 of the type, all but one starting life as a B-17G-VE-110 
in 1945. All the USCG Forts got to that service via the USN as part its 
acquisition of B-17s for its land based airborne early warning program.  I have 
chosen to replicate BuNo 77255 because its photo is in the public domain and it 
was assigned to CGAS San Francisco in 1952, the base that launched N4726V’s 
interceptor. It would accumulate 4720 flight hours before being declared surplus 
and sold in 1958. In the film and book, the “interceptor” is always referred to 
as the “Coast Guard B-17.” Probably few readers in 1953 had ever heard of a 
“PB-1G” but many could be counted on to recognize “B-17.”  
The Fort’s use as a SAR aircraft was developed by the USAAF, 
itself following the RAF’s lead in using large droppable life boats to support 
downed bomber crews a long way from home. Although there are photos of USCG 
PB-1Gs carrying these boats, they were apparently never used even in training, 
few PB-1Gs carrying them after the late 1940s. The other major visual 
modification to USCG Forts was in the installation of an SCR-717B radar in the 
chin turret position. There was evidently a problem with this radar, at least in 
Gann’s opinion (and perhaps that of the Coast Guard advisor to the film): 
  
The radar equipment on the interception ship, however, was notably 
inadequate, and the chances for a successful meeting of the two ships would be 
greatly increased if the crews could visually observe each other’s lights or 
pyrotechnics. 
                                                            [“The High 
and the Mighty”, p189] 
  
“Can you climb any higher? This stuff is not supposed to be very high and if 
we could get on top, interception would be much easier.” 
“Negative. We can climb, but don’t want to use the fuel. Every gallon is a 
mile nearer the shore for us.” 
“Okay….forget it. Our radar is not all it 
might be, but we’ll pick you up on it sooner or later if we keep those 
bearings going. What is the total number of people you have on board?” 
                                                            [“The High and the 
Mighty”, p225] 
  
 
 
B-17 Irony  
The United States Coast Guard operated manned B17s 
longer than any other United States Military service, PB-1G 77254 making the 
final landing at 1:46 p.m. on Wednesday 14 October 1959 at Elizabeth City Air 
Station, North Carolina. 14 years earlier the 8th AF was routinely 
putting up a 1000 a day from all those East Anglia airfields. 
 B-17G-95-DL s/n 44-82868 was accepted for service in the 
USAAF on 6 July 1945, and delivered to the USN shortly thereafter. Converted to 
a PB-1W it served in a variety of units until stricken on 10 July 1956 having 
logged 3484 hours of flight time. Sold in December 1957, it passed through the 
hands of a number of civilian owners finally being sold in 1983 to TBM, Inc for 
use in a three way trade with that firm, the USAF museum and the RAF museum at 
Hendon. TBM partially restored the bomber with an new Plexiglas nose and replica 
turrets, It was repainted to represent a 94th BG aircraft, and was 
ferried to Great Britain in the fall of 1983 for display at the RAF Museum’s 
 Bomber Command exhibit representing those thousands of B-17s that operated from 
England. It remains there yet, an interesting final resting place for a USN B-17 
that never served in the USAAF. Regardless, it continues to carry out its 
assigned duties with the innate elegance of the type and could not be in better 
hands. 
  
  
  
Pratt and Whitney R-2000 (DC-4)       Based on the 
R-1830 design; the R-2000 was basically an R-1830 with the cylinder bore 
increased from 5.5 to 5.75 in. By 1954, its only application had been in the 
C-54/DC-4 transport. 
Wright R-1820 Cyclone (PB-1G)         Thousands and 
thousands of these engines were made, most being G-series in WW II. At least 
seven production combat aircraft used it in WW II, most going into B-17s. It was 
the last round engine to go into a production US warplane intended to deliver 
ordnance - the Grumman S-2 Tracker series.

	Navigation, without INS or GPS  | 
   
 
  
There was a reason why mid-1950s trans-ocean aircraft had a 
crew position for a navigator and an astrodome. The crew member in the film who 
provides the dramatic intensity of the second half does not sit, IMHO, in either 
pilots’ seat, but rather that in of navigator Leonard Wilby. Gann uses mid-1950s 
aerial navigation to set the stage and build the suspense as we all wonder, 
“will 420 make it?” The author had seen over water navigation evolve to 
what we saw going on at the nav position of 420. The flight departs 
Honolulu on a Great Circle track ordered up by the FAA controller. Loran is used 
to periodically determine position along the track backed up with astrodome 
observations of the sun (“sun lines”) obtained via the Bubble Sextant.  The 
drift meter is used to determine wind. Radar on the USCG weather ship is used by 
its crew to confirm course and speed, based in turn on where the ship believes 
it to be. This information is passed to 420 by radio. After night falls, 
celestial navigation lines of position (LOP) again provide back up. In the film 
we see Lennie standing on a stool operating a bubble sextant in the astrodome 
behind the pilots to “shoot” various stars tabulated in the Air Almanac, which 
with other tables produces those LOPs on his chart.   
Post-runaway prop, the navigation excitement builds. After
420 descends into the clouds the stars can no longer be observed and only 
Loran is left.  Lennie makes a computational error by confusing statute miles 
and nautical miles. Now the “will we ditch or make SFO?” question is in doubt. 
The first to discover this are the radar operator and navigator of the PB-1G 
interceptor. The airliner-interceptor rendezvous had previously been arranged by 
radio bearings. Radio bearings from a ground beacon on the Farallon Islands get
420 in position to use ILS to bring 420 safely down.  
I thought at first the statute miles-nautical miles thing 
was a bit much, but Gann had undoubtedly seen it. And having once for my sins 
been a navigator (not in airplanes), I recalled some stressful incidents that 
make Lennie’s mistake more understandable. 
  
  
  
Minicraft supplies both kits for this project. The DC-4 is 
the latest Minicraft airliner release and shows a degree of sophistication 
compared to its first airliner releases. The nacelle/wing/cowling interface 
actually works well in this kit, and it has an ILS antenna, something I’ve found 
virtually impossible to scratch-build with accuracy in this scale.  
DC-4 (Minicraft 14500, with Pan Am decals) 
The first release of this kit was “The 
Sacred Cow.” complete with elevator to get the paraplegic President Roosevelt in 
and out of the airplane in a wheel chair. All subsequent releases have the 
feature. The elevator is of course not used and the cover for it must be 
installed and faired in. Assembly of the wings, fuselage and horizontal tail 
surfaces are straightforward with no fit issues other than a bit of filler 
around the joints of the latter. The fuselage, wing and tail surfaces were all 
painted and decaled before assembly. After assembly (engines, cowls and exhaust 
join the wings prior), all that’s left is the ILS antenna, the gear mounts, 
wheels, and gear doors. I no longer “do” antenna wires in this scale. .005 wire 
is accurate, but sags; .007 wire doesn’t sag, but it too large in diameter, at 
least IMHO. The kit has an exquisite little astrodome, the first Minicraft has 
provided for its 1:144 airliners.

Painting and Markings   N4726V in its TOPAC 
disguise carries the basic Transocean colors: overall unpainted aluminum, 
EXCEPT white fuselage top over a red cheat line from nose to tail. Plus, an 
orange-yellow vertical tail with a red stripe. The model fuselage was sprayed 
overall with Plasti-Cote Silver. Over this went a rough band of Model Master 
Insignia Red, to be masked off for the cheat line. Above and below this went 
Polyscale white and Alcad Aluminum respectively. The wing assembly and all other 
parts got the Alcad treatment as well.  
The vertical tail was sprayed with Polly Scale 
Orange-Yellow, which was then masked for a MM Insignia Red band at mid-height.  
White TOPAC markings on the cheat stripe were done 
with Model Graphics dry transfers. Those on the tail stripe were done from an 
ancient Microscale sheet of white alphanumeric characters. I attempted to use 
Model Graphics striping for the edging on the red sections so clearly visible in 
photos, but gave this up in the end. Over and under wing registration via Power 
Point and an ink jet printer. Movie footage is of the port side and no 
registration is visible in the normal fin location, so there is none on the 
model. But the registration is on the starboard side out of respect. [Hey, it’s 
MY mythical airplane]  
Minicraft C-54 kit 14520-r provided decals for the de-icer 
boots (thank you, Minicraft), cabin windows and doors, cockpit windows and 
anti-glare panel.    
 
  
PB-1G (Minicraft 14519)       
 
The kit of course is an armed B-17, the 
provision for which mostly disappears from the PB-1G. This kit is older than and 
not as crisp as the DC-4, and Minicraft continues the tradition of most kit 
makers doing this aircraft in not getting the windshield right. Mounting hole 
for the top turret was filled in; ball turret mounting surface was sanded smooth 
to conform to the fuselage curvature. And, the fairing behind the chin turret 
mounting hole was removed and the resulting hole filled. A piece of ¼” wood 
dowel represents the radar housing, mounted where the chin turret was once 
installed. The recessed outlines of the waist position windows are overdone and 
located in the wrong spots; these were filled in and sanded smooth.

As part of the conversion of these aircraft to 
boat-carrying PB-1Gs, the ADF football was moved to the top of the fuselage aft 
of the cockpit. Photos of many USCG PB-1Gs show two of these devices, the second 
apparently back in its original position. I presume this was done after the 
boats were dropped as operational equipment. Photos show most a/c had two upper 
fuselage whip antennas, plus the empennage antenna mast. I can find only one a/c 
with radar altimeter antennae, so #77255 does not get them. It does get what 
seems to be a near-universal set of side-by-side under fuselage antenna masts 
mounted about on a line with the wing trailing edge. Now-redundant .50 cal gun 
barrels supply the three antenna masts; the ILS antenna was fashioned from .009 
wire. 
Painting and Markings   At some point in their 
career USCG PB-1Gs were painted an overall aluminum color; this was done with 
Alcad Dark Aluminum over Plasti-Cote Silver. Other painted areas were the 
Orange-Yellow wing tips and fuselage stripe (Poly Scale) with 6” black borders. 
Photos of CG PG-1Gs show mixed use of deicer boots and I would rather not have 
dealt with them, but my chosen a/c has them, so MM Black was used to put them on 
the replica of #77225. Polly Scale Flat Aluminum was used for the fabric control 
surfaces and also (with a bit of black to darken it) for the “hot” section of 
the nacelle aft of the cowlings. The cockpit windows clear part fits poorly; it 
was faired in with putty. The window/windshields in this piece and well as the 
waist windows, window in the entry door, and those in the radio position are 
represented in black paint. The window areas were roughly painted in black and 
homemade masks were applied prior to final painting. 
Superscale 72-84 supplied the national insignia; an old 
Esci sheet supplied the “U.S. Coast Guard for the fuselage and fin, and the USCG 
insignia forward of the wings. Once again Power Point and a printer did the 
large “USCG” above and below the wings, the abbreviated serial on the fuselage, 
and the serial and type on the fin. The black border for the yellow striping 
came from Model Graphics MG759.

Narrative: 
The DC-4 took off from Honolulu at 22:47 PST for a fight to Los Angeles. At 
05:54 PST the pilot reported a bad fire in the no. 2 engine and stated that a 
ditching might become necessary (“…we may have to put it in”). Nothing more was 
heard …Extensive search efforts were discontinued after 5 days; nothing had been 
found. A total of 15 hr 17 min maintenance delays had occurred on the Los 
Angeles-Philippines round trip. Among the causes was a recurring oil leak in 
the propeller governor assembly for the no. 2 engine.  
  
PROBABLE CAUSE:  “In-flight No. 2 engine fire for an undetermined cause, 
resulting in ditching at sea.” 
[Aviation Safety Network] 
  
N4726V was lost 10 years and four months after it flew the flight 
sequences in “The High and the Mighty” apparently for the same reason 
that almost took down the mythical TOPAC flight 420, “a runaway prop 
and engine fire occurring at night halfway between Hawaii and the mainland.”
