In 2018 I posted up the two blogs linked below on the topic of Levittown, the postwar mass housing construction phenomena in the east of the United States.

In the late 1940s Bill Levitt’s New York company started constructing a series of new housing estates in the Atlantic seaboard states, succeeding in building affordable houses in double-quick time and on a mega-scale. Not long after Levittown showed the way, a triad of developers in California started planning their own gigantic scale home building project in Lakewood, Los Angeles County, to reap the rewards. The three ’amigos’, Ben Weingart, S Mark Taper and Lou Boyar, formed the Lakewood Park Company (LPC) and bought close on 3,500 acres from the Montana Land Co (previously sugar beet and lima bean fields adjacent to the city of Long Beach)¹. With Weingart’s extensive connexions in LA financing circles, the LPC got backing to the tune of $8.8 million from the Prudential Insurance Co, and were cleverly able to exploit a legal anomaly, leveraging a stack of federal finance to pay the large part of the private project’s expenditure [Kevin Starr, Golden Dreams: California in an Age of Abundance, 1950-1963, (2011)].

A frenetic work schedule
The LPC utilised the same approach to construction as the Levittown developers. Every aspect was coordinated, synchronised like clockwork, the 4,000-strong work force was divided into 30 separate teams each with their own specialised task. Rapidity of construction was achieved by adopting the production efficiency methods learnt during WWII, foundations were laid post-haste (15 minutes to dig the hole by machine and not much more to fill it with concrete). Output was phenomenal, they were building around 40 to 60 new houses a day² (even managing in a single day to reach a record tally 110!).
Selling the American Dream
When Lakewood Park’s subdivision of model homes—complete with a “Tile Pullman lavatory” and a built-in ‘Pulverizer’ garbage disposal unit in the kitchen—was opened up to the public, the sales office was inundated with aspiring home-owners all seeking their piece of the “Father Knows Best’ fantasy lifestyle. One salesman sold 107 of the homes in a single hour [‘A New Kind of City…Lakewood’, Los Angeles Almanac, www.laalmanac.com]. Many were “sold off the plan” at a time before that term was in vogue. The cost for a Lakewood ‘model’ mostly ranged from $7,500 to $9,500. Like Levittown, Lakewood Park particularly appealed to WWII veterans who under the GI Bill were guaranteed advantageous terms, no down payment and 4% interest over 30 years. Lakewood’s population exploded – what was a small unincorporated village in 1950 became a ‘city’ with in excess of 70,000 inhabitants by 1953.

We’re all white thanks!: ‘Paradise’ homes for the white middle class
Again as with Levittown the ugly spectre of racism raised its head in the Fifties Lakewood Park ‘model’ lifestyle. One former sales manager for the LPC explained that his part of his role involved guided homogeneity, dissuading black (and Latino) families from buying into the estate on the grounds that the overwhelmingly white neighbours would object to their presence on the same block. This was part of a wider practice of “steering buyers into racially defined neighbourhoods” which persisted into the 1960s…the developers’ rationale being “that racially mixed communities (they believed) would not retain their resale value” [‘Suburban pioneers’, Lakewood City,www.lakewoodcity.org].

Like the Levittown prototype, Lakewood Park’s rapid-build assembly-line construction resulted in 17,500 houses springing up inside three years, a model planned community serviced by the construction of the Lakewood Center, at the time the largest shopping mall in the country (with parking for 10,000 vehicles)³ [‘Lakewood Community History’, LA County Library,, www.lacountylibrary.org]. Time magazine called to the largest housing development in the world, but some critics bemoaned the monotony of its grid-pattern streets and the houses’ sameness…it was however not quite Levittown Mach II, there were ‘subtle’ variations in landscaping and the use of slightly different home designs, the developers were careful to avoid Levittown’s error⁴ of having identical design homes next to each other in the same block [‘Lakewood California History’, Lakewood City,www.lakewoodcity.org].Source: Pinterest

Developers with “laugh-lines around their pockets”
A Senate hearing in 1954 troubled by the development’s ramifications concluded that the bulk of the profits from Lakewood Park‘s land sales and retail development ended up in the pockets of the LPC syndicate…finding that Weingart, Boyar and Taper in fact risked very little of their own money on the venture (about $15,000 altogether) by being able to (legally) rely on the accessible federal financing. Against their meagre personal outlays, newspapers estimated that the triumvirate made nearly a cool $12 million each from the deal (‘Lakewood California History’).

Footnote: The Lakewood Plan, “Contract City“
Lakewood became an incorporated city in 1954—following a divisive community campaign and an attempt by larger neighbour Long Beach to absorb it—but of a unique kind. Foundation attorney John Todd and the developers opted to contract out the new city’s essential municipal services to LA County (police force, fire brigade, sanitation services, etc), an innovation (Lakewoodisation’) later copied widely in California and in other states (‘A New Kind of City…Lakewood’). The stated reason for going the “minimal city” route was financial efficiencies, but Gary Miller argues that self-advantage was the real purpose, allowing the wealthy to “insulate (their properties) from the burden of supporting public services…(thus) zoning out service-demanding low-income and renting populations”, “fueling white flight from Los Angeles” [quoted in Mike Davis, City of Quartz: Excavating the Future in Los Angeles, 1990]

🚁 Helicopter, from the Greek: helix (‘spiral’ or ‘whirl’ or ’convolution’) + pteron (‘wing’); into French: hélicoptère.

We know that manned, powered, heavier-than-air flight in an aircraft began with the Wright brothers in 1903 at Kitty Hawk, North Carolina—unless that is you accept the audacious alternate candidate, Gustave Whitehead’s flight in Connecticut made two years earlier🅰—but when did the first helicopter get off the ground? The primitive archetype seems to be the brainchild of Frenchman Paul Cornu. Cornu, like the brothers Wright, started off as a bicycle maker before veering off into the nascent field of aerodynamic engineering.

Getting the concept off the ground
Near Lisieux in northern France in 1907, Monsieur Cornu became the first person to (ever so briefly) pilot an airborne rotary-wing, vertical-lift aircraft. The rotorcraft (using an unpowered rotor in free autorotation to develop lift) from Cornu’s own design was a twin-rotor job, the blades rotating in opposite directions which neutralised the torque. M. Cornu’s craft levitated about 1.5 metres off the ground, hovering for some 20 seconds. The Cornu ”Ur-copter” wasn’t manoeuvrable at all (requiring manpower to hold it in position from the ground) and therefore wasn’t practical, but it is considered to be a forerunner of the modern helicopter.

De la Cierva and the autogyro
From 1912 on, numerous inventors and engineers were turning their hands to building prototypes of the rotorcraft, but with limited or ephemeral success. Compared to fixed-wing aircrafts, progress with rotorcrafts evolved very slowly, due to intrinsic problems with torque, dissymmetry of lift and control. Sikorsky (below) spent 30 years working on developing helicopters before his breakthrough. Etienne Oehmichen, whose early prototypes included vertically-mounted rotors and a tail rotor, allowing it to fly a distance of one kilometre in 1924! Oehmichen was also the first to carry passengers in his Oehmichen No. 2 helicopter. By the early 1920s Spanish aviator and engineer Juan De la Cierva built the autogyro (sometimes called a “windmill plane” or ‘gyroplane’)… his success advanced the understanding of rotor dynamics. Cierva’s autogiro had air safety in mind, proposing a solution to the craft losing its lift or stalling even at very low speeds. The Spaniard worked out that the autogyro’s rotor function is driven by the speed of the air, cf. the helicopter’s which depends on a motor…in the descent of the autogyro the rotor functioned as a kind of parachute according to Cierva. Ultimately, the helicopter’s superior velocity made it the preferable mode of aerocraft, however Cierva’s principle of the self-turning rotor remained a vital contribution to the later development of functional helicopters. Cierva’s flapping rotor blades has been described as “the single most important discovery in helicopter development” (CV Glines). A countryman of Cornu’s, Louis Bréguet, also experimented with the autogyro in the Thirties, his Bréguet-Dorand “Gyroplane Laboratoire” improving both the craft’s speed to 120km/h and its control capacity.
Another step forward in the evolution of helicopters came from Nazi Germany. Professor Heinrich Focke applied Cierva’s pioneering work on aerodynamics to the task of transitioning from the limitations of the autogyro to the creation of a “pure helicopter”. In 1936 Focke and Gerd Achgelis‘ Focke-Wulf Fw-61 smashed existing helicopter records for range and altitude and demonstrated autorotation descent to landing. This plus a control system much more reliable and robust than earlier rotorcrafts leads many aviation geeks to consider the Fw-61 to be “the world’s first truly functional helicopter”.

Sikorsky’s practical copter
What Cornu started, Russian-born American designer Igor Sikorsky brought to commercial fruition. Sikorsky invented the first mass-produced, and in the opinion of many, the first practical helicopter, the VS-300, in Stratford, Connecticut in 1939🅱. In commercial production called the R–4, it would go on to play a significant role in the Second World War. By the war’s end Sikorsky had added the R–5 and the R–6 models, specifically designed for the military and specialising in search-and-rescue missions. Although he didn’t invent the first prototype of the helicopter, Sikorsky is commonly thought of as “the father of helicopters” because “he invented the first successful helicopter upon which further designs were based”. The VS-300 became the model for all modern single-rotor helicopters.

A symbol of modernisation1964 was a bumper year for the Japanese. In October of that year two events helped the country finally break free of the persisting shadow of an an ultimately inglorious and painful World War II experience. Japan’s capital Tokyo staged the XVIII Summer Olympic Games and Japan launched its iconic high-speed train service, the Shinkansen (meaning literally “new trunk line” or “new main line”), popularly called the “Bullet Train” (弾丸列車 dangan ressha) because of the similarity of the initial (0 series) design of the nose✲. Together, the Olympics and the Shinkansen’s arrival symbolised the fulfilment of “Japan’s recovery from the devastation of war and the beginnings of Japan’s stratospheric rise as an economic superpower” (Braser & Tsubuku)⌧.
(Source: JapanRail Pass)
Planning for the Shinkansen started in the 1950s and had its origins in the realisation that Japan’s conventional rail network was reaching capacity and not up to the demands of modernisation. The country’s geography, climate and population needed a faster, modern network. A VFT was identified as imperative for a land mass that stretched over several islands north to south for thousands of kilometres. Construction (and operational) challenges were manifold and extremely formidable – a mountainous country subject to earthquakes, typhoons, heavy rain and snow and flooding (Hood).
The original rail service, the Tōhoku Shinkansen connected the three principal cities on Honshu island, Tokyo, Nagoya and Osaka. The impact on intra-Japan rail travel was immediate and dramatic. With the sleek “whiz-bang” new train reaching speeds of up to 210 km/h⍟, the journey between Tokyo and Shin-Osaka was cut from 6 hrs & 30 mins in an conventional train to around 4 hrs & 10 minutes in the Bullet Train! (in 1965 it was reduced again by a further hour)✪.

An accident-free record
As impressive as it is, the Shinkansen’s most impressive attribute is not its rapid speed, but its peerless safety history over a period of 57 years. The Shinkansen service has not suffered a single casualty or even one injury in the totality of its trips. The only blots on the perfect record in this time have been two derailments (one in an earthquake and one in a blizzard) (Glancey).

Rail privatisation
Originally the Shinkansen train network was built and operated by the Japanese government (Japanese National Railways), but in 1987 it was privatised, coming under the ownership of six Japanese Railways Group (JRG) companies. Today they runs nine separate lines, smoothly criss-crossing the densely-populated Honshu and Kyushu islands and extending to the northern island of Hokkaido, it’s spotlessly clean carriages carrying an average of around 150 million passengers a year (JapanRail Pass). The network has two types of Shinkansen trains – Kodama Express and the limited stop Hikari Super Express train.

Personifying Nihongo efficiency
The latest iteration of the Shinkansen, the N700 train with its aerodynamic duckbill-nose completes the Tokyo–Osaka journey in 2 hrs & 25 mins⌽. The N700S (Supreme) has the advanced capacity to continue operating during earthquakes. Punctuality is also the Shinkansen’s strong suit – the average delay for the railway’s fleet of trains is less than 60 seconds (Dow). The Shinkansen’s efficiency represents “an elegant solution for shuttling workers from one dense city to another” and doing it rapidly, workers living “in distant, relatively undeveloped areas can commute to Tokyo (for instance) in two hours” (Pinsker)〥.
Local dissenters to the “love affair” with the Shinkansen
The Shinkansen has been achange agent for Japanese economy and society, a potent symbol of the nation’s development. Research indicates that those urban hubs with a Shinkansen station experience higher population and higher employment growth rates (Sands). Not everyone in Japan however is 100% behind the Bullet Train companies’ unbending “full-steam ahead” approach. There have been pockets of local rural opposition pushing back against JRG’s relentless land acquisition process. Residents along the routes whose quality of life has been adversely affected by Shinkansen’s noise and vibration have also been vocal in their complaints (Hood).

Eye on the future
Not resting on the laurels of the Shinkansen series’ cutting-edge technology, research has been happening since 1962 on a linear motor railway system. In the 2000s JR Central commenced testing a Maglev train prototype, the Linear Chūō Shinkansen, which can reach a speed in excess of 500 km/h – this service is slated for introduction in 2027 (Nippon.com).
Postscript: To transfer technology or not to transfer technology?
Japan’s success with the Shinkansen has spawned imitators. China’s vaulting high-speed train ambitions—while denying charges of intellectual piracy by copying the Shinkansen—has seen it have to resort to reliance on German and French as well as Japanese VFT technology for its own high-speed train. Consequently some Japanese railway insiders have criticised the technology leak to China, lamenting that when you put high technical ability on display (as Japan has with its crown jewel train), it gets copied. However there’s no consensus on this point within Japanese government and business. Central Japan Railway Co (owner of Shinkansen and Linear Train Technology) have actively participated in the development of US high-speed trains on an ongoing basis, proponents of this approach argue that by not exporting the Bullet Train technology to countries with large markets, Japan risks losing out to competitors who’ll get in first…the Overseas Rapid Railway Project’s Katsunori Ochiai summed up the gains from exporting: “If the new Japanese model Shinkansen and linear trains are adopted in America, the market for manufacturers of the carriages and signal systems would be greatly expanded.” (Shimbun).
Shinkansen technology transfer’ first export overseas was to Taiwan, successfully helping to develop the Taiwanese High-Speed Rail system.

Before the Maglev (magnetic levitation) very fast train (VFT) system was developed—which we can observe today in commercial operation in Japan, China and South Korea—there was the Aérotrain prototype in France✳. Its story starts in the early 1960s when France was faced with a need to revitalise its declining railway sector. In 1963 aviation engineer Jean Bertin pitched his Aérotrain concept for a VFT mass transit system to France’s public transport czars. Over the next two years the government created a state company to study the Aérotrain while Bertin developed his 1:20 scale model train into the full-scale prototype.
Bertin’s invention was a Tracked Air Cushion Vehicle (TACV), a hovertrain riding on a cushion of air atop “a simple reinforced concrete track or guideway”∆. The Aérotrain design borrowed from the lifting technology of hovercraft vessels and from the arliner’s turbo fan. Both the ‘wheelless’ vehicle and the T-shaped track were radical designs at the time. Bertin’s intention was to come up with a simpler and cheaper alternative to the Maglev trains then in experimentation (‘France’s Aérotrain’, Ian Brown, Google Sighting, 10-Oct-2013, www.googlesighting.com).

Exporting the hovertrain
By 1966 Bertin & Cie had built its first Aérotrain test track (6.7km-long) at Essonne, south of Paris. Interest in Bertin’s hovertrain concept was international, Britain designed its own version, the RTV-31 Tracked Hovercraft, and constructed a test track in 1970, in the US, Rohr Industries contracted with Bertin’s company to do the same. Bertin developed several prototypes, the ultimate bring the Aérotrain 180 HV, a 25.6m-long hovertrain seating 80 passengers and attaining a world record speed for overland cushion vehicles (430.3 km per hour).
RTV-31, UK (Source: Geograph) Photo: www.grandsudinsolite.fr
Technical issues
L’Aérotrain prototype presented Bertin with a series of design challenges — the system would require new elevated guideways for every implementation; the craft when passing other trains or entering tunnels experienced sudden changes in air pressure; the Aérotrain’s gas turbines operated with giant propellers which generated tremendous noise, necessitating a reduction in speed in urban areas (making it unattractive to some interested authorities) (‘Aerotrain’, Wikipedia, http://en.m.wikipedia.org).
Photo: www.grandsudinsolite.fr
Aérotrain, not the people’s train?
Although the technocrats in the state apparatus were favourably disposed to Bertin’s Aérotrain—especially DATAR (Delegation for Territory Planning and Regional Action)—its acceptance was not universal within France. Technical difficulties like the noise levels turned . many Parisians away from the vehicle. With such a “cutting-edge” special project, a perception grew that Aérotrain travel was for the elite commuter, not the average French worker, “(serving) only a rarefied strata of society”⟴ (Guigueno, Vincent. “Building a High-Speed Society: France and the Aérotrain, 1962-1974.” Technology and Culture, vol. 49, no. 1, 2008, pp. 21–40. JSTOR, www.jstor.org/stable/40061376. Accessed 20 June 2021).
180 HV Aérotrain Expérimental
Cost was increasingly a factor working against the Aérotrain, the system, requiring a dedicated track would be costly to implement. The 1973 oil crisis (also see End-note) and the imposition of new strictures on state spending didn’t help, leaving the Aérotrain Company in financial difficulties (Guigueno). Public authorities were increasingly reluctant to fund the Aérotrain project.
SNCF (Photo:www.france24.com)
The modern versus the traditional
The bureaucracy and SNCF (French National Railway Company) had its own agenda, which deviated from the objectives of Aérotrain. Transport planning in France was committed to a policy of maintaining the efficacy of “traditional modes of urban transport”, heavily investing in Aérotrain ran counter to that. The influential SNCF saw it as a “competitive threat to the traditional railway” (Guigueno).
The lethal blow came in 1974. French president, Georges Pompidou, who had been a moderniser, died. His more conservative replacement, Valéry Giscard d’Estaing, coming down on the side of traditional technologies terminated the Aérotrain project just two months into office. The reasons for Giscard’s opposition to the project are not certain, Guigueno speculates that perhaps the president was reacting to Aérotrain’s unpopularity with the Paris suburbs and their representatives. The recently-approved Cergy—La Défense link for Aérotrain engendered scepticism from locals due to delays and cost overruns and was also canned by Giscard. Giscard whose previous ministerial job was controlling the nation’s pursestrings probably thought Aérotrain was too much of a financial risk at the time (‘Transport That Never Was Part 1: Aérotrain, a hovertrain in Paris’s western suburbs’, Fabric of France, 18-Feb-2020, www.fabricoffrance.com).
TGV Hi-Speed Train (Photo: EURail Pass)
Replacing a revolutionary VFT with a conventional VFT
Aérotrain’s misfortune was TGV’s good fortune. The Giscard government switched from Aérotrain to TGV¶, a rival turbo train design inspired by Japan’s Shinkansen, as the preferred provider for France’s inter-city high-speed rail service. In 1981 TGV became the VFT carrier for the new Paris to Lyon link. Essential to TGV’s triumph over Aérotrain was SNCF’s strategy of “develop(ing) TGV as a supplement to, rather than a replacement for the traditional rail service” (Guigueno)❂. On the matter of infrastructure TGV was a full circuit in front of Aérotrain. The TGV was a better fit with its huge advantage over Aérotrain in compatibility with existing railways in France, and it could extend, beyond the high-speed network, over much greater distances (‘Transport That Never Was’).
Abandoned Aérotrain test track near Orléans: section of Saran—Ruan monorail still in existence
Aérotrain’s eclipse was devastating for its inventor … Bertin, already stricken with cancer, died several months later, aged just 58. In 1977 the Aérotrain project was abandoned, bringing an end to the Gallic hovertrain dream.
End-note: The hike in the world oil price after 1973 posed an acute problem for the TGV prototype, being as it was powered by gas turbines. Sagely, the company switched its prototype to all-electric trains to overcome this, and stay cost-competitive with Aérotrain (‘Transport That Never Was’).
