The AƩrospatiale-BAC Concorde is a turbojet-powered supersonic passenger
airliner, a supersonic transport (SST). It was a product of an
Anglo-French government treaty, combining the manufacturing efforts of
AƩrospatiale and the British Aircraft Corporation. First flown in 1969,
Concorde entered service in 1976 and continued commercial flights for 27
years.
Among other destinations, Concorde flew regular
transatlantic flights from London Heathrow (British Airways) and
Paris-Charles de Gaulle Airport (Air France) to New York JFK, profitably
flying these routes at record speeds, in less than half the time of
other airliners.
With only 20 aircraft built, their development
represented a substantial economic loss, in addition to which Air France
and British Airways were subsidised by their governments to buy them.
As a result of the type's only crash on 25 July 2000 and other factors,
its retirement flight was on 26 November 2003.
Concorde's name
reflects the development agreement between the United Kingdom and
France. In the UK, any or all of the type—unusual for an aircraft—are
known simply as "Concorde". The aircraft is regarded by many as an
aviation icon.

Abstract
We report the results of an experimental comparison of dierent airplane boarding methods. This test was conducted
in a mock 757 fuselage, located on a Southern California soundstage, with 12 rows of six seats and a single aisle.
Five methods were tested using 72 passengers of various ages. We found a significant reduction in the boarding times
of optimized methods over traditional methods. These improved methods, if properly implemented, could result in a
significant savings to airline companies.

iPads could replace paper charts in planes
iPads could replace paper charts in planes
Apple's iPad may soon find its way onto your next commercial flight, and not just in the cabin as an entertainment device. Major airlines and a charter jet company are considering using the tablet as a way to replace paper navigation charts and laptops both on the ground and during flight.
So far, no US airline has adopted iPads exclusively, but Delta Airlines and Alaska Airlines are testing the device for navigational purposes. Alaska spokeswoman Maryanne Lindsay told the Seattle Times that the carrier is running a trial program with a select group of pilots. Calls made by CNET to the Alaska Airlines press office were not returned at the time of this writing.
Switching to iPads or other tablet devices would cut down on paper, and on the equipment pilots have to carry. While some specially designed laptops, or "electronic flight bags," can weigh up to 8.2kg, the current iPad weighs just just 730g (the recently announced iPad 2 is a tad lighter). What's more, it should save airlines money as well.
Yes, there's an app for that
To power the iPads, Englewood-Colo.-Jeppesen Systems has developed an iPad app called Mobile TC that delivers electronic charts (available now for free in the iTunes App Store). At the the time of this writing, Mobile TC covers only airport terminal charts, but Jeppesen spokesman Brian Rantala told CNET that the app will be expanded to cover in flight use.
Last month, the Federal Aviation Administration authorized private jet charter Executive Jet Management to begin using the app as an alternative to paper aeronautical charts. A wholly owned subsidiary of Boeing, Jeppesen also developed an iPhone and iPad app called CrewAlert manage airline crew fatigue.
And back in the cabin, Qantas subsidiary Jetstar is close to using iPads as in-flight entertainment units on selected Airbus A320 and A330 aircraft. Though JetStar initially announced its iPad plans last summer, Flightglobal reported today that the airlines airline has compiled a presentation for major movie studios.

The Pain of Change at Boeing
By HARRY HURT III
Published: November 20, 2010
ONCE upon a time, major American companies and their employees treated each other as family. The companies provided job security and lifelong benefits; in general, workers were loyal and engaged in their jobs, the occasional strike notwithstanding.
But that relative harmony ended with the advent of globalization, according to “Turbulence: Boeing and the State of American Workers and Managers” (Yale University Press, 238 pages), a meticulous and illuminating case study of the nation’s largest manufacturing exporter.
The book has four authors with a combination of academic and private-sector backgrounds: Edward S. Greenberg, Leon Grunberg, Sarah Moore and Patricia B. Sikora. Based on their research and experience, they write: “The very innovations and changes Boeing introduced to remain a leading producer of airplanes — altered management strategies, pervasive technological changes, extensive outsourcing, broad global partnerships, massive layoffs, and drastically altered ways of working — produced stress and turbulence in the lives of workers and managers alike.”
And the authors say Boeing’s woes are a cautionary tale for corporate America because the company suffered despite extraordinary advantages. “As one of only two manufacturers of large passenger jets in the world, Boeing occupies an extraordinary economic niche, and has had generally enlightened policies, along with strong unions to protect its employees,” the authors write. “Many American companies and their employees, in virtually every economic sector, face similarly strong competitive pressures but without Boeing’s advantages.”
The book focuses mainly on the period from 1996 to 2006, a span that encompassed the company’s merger with McDonnell Douglas, a strike by engineers and technical workers, ethics scandals in top management ranks, and the start of a major new passenger jet project, the 787 Dreamliner.
The research included four separate surveys, in 1997, 2000, 2003 and 2006. They tracked a cohort of 525 continuously employed Boeing workers and managers as well as scores of people who left the company during the course of the study.
After generally worsening between the first and the third surveys, employee attitudes toward the company showed some improvement by the 2006 poll, as some of Boeing’s changes took root. But according to the authors, morale issues remained.
One of the book’s most notable findings has to do with outsourcing. As seen in the production of the 787 Dreamliner, its new wide-body jet, the effects were decidedly double-edged. Two aims of the outsourcing were to cut costs and to gain access to more foreign markets; both of those goals were largely achieved.
But the parts contracts for the 787 were let to 135 sites in two dozen countries. In theory, the parts could be snapped and fitted together — much like pieces of a model airplane — at the Boeing plant in Everett, Wash. Yet in practice, the authors say, the process proved much more complicated, “something Boeing discovered to its considerable discomfort in 2008 and 2009 when many of the sections neither snapped nor fit properly.”) Production of the 787 would fall two years behind schedule.
Many survey respondents worried that outsourcing would result in “the bleeding of engineering knowledge and jobs to global partner companies, hurting both Boeing and the United States in the long run,” the book says. One engineer with 27 years of experience at Boeing opined that “we are giving away the farm.”
The authors found that the decision by top management to emulate the so-called “team” model, pioneered by Japanese companies like Toyota, had a generally negative effect on employee morale rather than promoting a sense of empowerment.
The authors write that “perhaps more in sorrow than in anger,” many people said that “the notion of Boeing as a family, where employees’ contributions were respected as a source of competitive advantage, was a thing of the past, replaced by Boeing as a team where people and positions were expendable or interchangeable with other workers around the world.”
Perhaps even more surprising was how disaffection with the changes at Boeing permeated every level of the company. “Importantly, at the end of our study period, there was no statistical difference between the number of managers and nonmanagers regarding their intentions to quit Boeing,” the authors report, later adding that “as the organization flattened, the career ladder became compressed to a step-stool; many managers and employees felt dead-ended as opportunities for advancement seemed to evaporate.”
FOR an academic study, “Turbulence” is refreshingly accessible, with a coherent narrative punctuated by no more than the minimally requisite charts, and only occasionally marred by overworking a comparison of the company-employee relationship to a failed marriage.
The interview excerpts are often heart-wrenching, and the long-term, disciplined nature of the authors’ research gives their findings credibility. For these reasons alone, “Turbulence” should be required reading for anyone at a major American corporation, especially in top management.
Arguably, the single glaring weakness is in the book’s prescription for fixing the workplace. Insisting that neither companies nor employees can go it alone, the authors call for government to protect American workers and provide employment opportunities through “safety net programs based on pooled-risk insurance principles.”
That may sound like an ideal combination of the family model and the team model. But given the outcome of the recent midterm elections, any proposal to enlarge the role of government in the private sector is not something the American public is likely to buy into anytime soon.

PTQ: Put Together Quickly
~Air & Space magazine
This time-lapse video shows Boeing’s “Aircraft On Ground” team repairing damage to a 767 that was inadvertently shoved into a blast fence by a tow tractor. The AOG team had to pull the airliner in two, insert a new bulkhead, and put it all back together again—in three weeks. Boeing produced the video.

The Opening of the Commercial Jet Era

a little something to bring us all back to our roots :) Ben
Like perhaps no other single technology, the jet engine revolutionized air travel around the world. Unlike the old propeller-driven planes that were powered by piston engines, jet planes could fly at tremendous speeds, thus cutting down travel time. Jet-equipped airplanes also could climb faster and fly higher. Both the U.S. Air Force and civil aircraft builders found these capabilities attractive in the years after World War II when international contacts stretched across the globe. There were, however, major concerns about transferring jet engine technology to the commercial aviation sector. Airline executives in the postwar era were aware that, although jet engines were simpler than the old piston engines, they also had high operating temperatures that required very expensive metal alloy components that ultimately would affect an aircraft's longevity and reliability. Moreover, jet engines used far greater amounts of fuel. The initially low takeoff speed would also require longer runways. All of this added up to increased costs. As a result, U.S. passenger air carriers did not support the building of jet airliners in the immediate postwar years, and adopted a “wait-and-see” approach before embarking on this risky path.
The British Overseas Aircraft Corporation (BOAC), the national British carrier, first introduced a commercial jet airliner into service. The 36-seat Comet 1, built by De Havilland, flew for the first time on July 27, 1949. BOAC inaugurated the world's first commercial jet service on May 2, 1952. Initial flights took passengers from London to Johannesburg in South Africa, with stops in Rome, Beirut, Khartoum (in Sudan), Entebbe (in Kenya), and Livingstone, near Victoria Falls. At the time, the top cruising speed of the most well known piston-engine aircraft, the DC-3, was about 180 miles per hour (290 kilometers per hour). With the Comet, passengers could travel comfortably at 480 miles per hour (772 kilometers per hour), making it a revolutionary leap in air travel. The Comet also provided conditions that contrasted sharply to piston-engine planes: the planes were vibration-free and relatively quiet.
Unfortunately, the Comet was the victim of a number of tragic accidents, and BOAC suspended flights within two years. Engineers found that the planes suffered from metal fatigue, especially around rivet holes, due to the need to repeatedly pressurize and depressurize the aircraft. In 1952, Pan American Airways had already put in an order for the new 76-seat Comet 3, but the crashes of the earlier Comet put the contract into doubt. By this time, domestic U.S. companies had begun their own programs to build jet airliners. Several factors, such as improved jet engines, now convinced these companies to reconsider their initial reluctance to build commercial jet planes.
Of all the airlines in the United States, Pan American, which the U.S. government considered its “chosen instrument” to represent the American commercial air fleet abroad, was undoubtedly a pioneer in embracing jet aviation. Juan Trippe, the airlines' legendary chief executive officer, had early on expressed a keen interest in operating a passenger jet service capable of flying nonstop across the North Atlantic. Having seen the bright promise of the British Comet fade, Trippe played off two of the biggest domestic airplane builders, Boeing and Douglas. Both companies vied to appeal to Pan American's needs and offered the Boeing 707 and DC-8, respectively. In October 1955, Trippe signed contracts with both companies to buy 45 of these jets (20 707s and 25 DC-8s). Exactly two years later, Boeing rolled out the first operational 707, a Boeing 707-120, and on October 26, 1958, amid much fanfare, Pan American inaugurated its New York-London route, ushering in a new era in the history of passenger aviation. On the very first flight, which made a stopover in Newfoundland, there were 111 passengers, the largest number ever to board a single regularly scheduled flight. Coach fares were $272, about the same as one would expect to pay for a piston-engine flight across the Atlantic.
At first, BOAC competed hard with Pan American. In fact, in order to preempt the Americans, BOAC had rushed ahead and inaugurated its own transatlantic service on October 4, 1958, just three weeks ahead of Pan American. BOAC used the new De Havilland Comet 4, which incorporated improvements to remedy the problems with the older Comet 1. Although BOAC fared quite well, its success was nothing compared to Pan American's. With its rapidly expanding use of the Boeing 707, especially on the transatlantic route, Pan American began a period of almost unchallenged success in the international airline industry. The airline, for example, was the first to recognize the importance to passengers of nonstop flights on long trips; it negotiated with Boeing for a version of the 707 that could fly for a longer time without refueling, known as the 707-320.This allowed the airline to introduce true intercontinental service with nonstop London-to-New York flights on August 26, 1959. This was a perfect case of a dominant air carrier playing the lead role in defining the characteristics of a new class of jets that the industry would produce. The 707-320 was eventually adopted by as many as eleven other airlines within a year.
Within the United States, National Airlines became the first to begin jet service, using leased Boeing 707s, on December 10, 1958. American Airlines offered the first domestic jet service using its own aircraft on January 25, 1959 with a flight from New York to Los Angeles. With this coast-to-coast service, American had a big competitive coup; the two other major domestic U.S. airlines, Trans World Airlines (TWA) and United Airlines, had not anticipated the imminent use of jets for domestic service. TWA quickly scrambled to catch up, and using a single Boeing 707, it joined the coast-to-coast flight market in March 1959. The last minute move helped keep TWA afloat through a difficult period of economic loss.
Not all airlines pinned their hopes on the Boeing 707, however. Douglas had unmatched experience in building the best passenger airliners of the world. United Airlines and Delta both began flying the DC-8 passenger jets in September 1959—latecomers to the domestic jet market precisely because they had depended on Douglas, which introduced jets after Boeing. Eastern Airlines joined them in domestic jet services in January 1960.
One of the more unusual aspects of the coming of the jet era was the speed with which airlines internationally adopted these new aircraft. Partly because of Pan American's example, airlines from all over the world replaced piston-engine aircraft with jets at an unprecedented pace. The Soviet national airline Aeroflot was part of this explosion. In fact, Aeroflot held the distinction of offering the world's first regularly scheduled and sustained passenger jet service with its Tupolev Tu-104 aircraft. Aeroflot opened service from Moscow to Irkutsk (in the Soviet far east) in September 1956. Elsewhere, by 1961, just three years after Pan Am's first jet flight, jets were flying routes over the North and South Atlantic and the Pacific; in the domestic United States, Europe, and East Asia; North-to-South America routes; Europe-to-Africa routes; Europe-to-Australia routes; and even to the Arctic regions. International airlines such as Air France, Lufthansa (Germany), KLM (Netherlands), Iberia (Spain), QANTAS (Australia), SABENA (Belgium), Air India, SAS (Scandinavia), Swissair, El Al (Israel), and JAL (Japan) were all using the Boeing 707, the DC-8, or in lesser numbers, the Corvair CV-880 jet on major international routes.
Although many other airlines were the first to offer regular services on various international routes, it was Pan American Airways that set the standards for service in the new jet era. Pan American's pioneering partnership with Boeing, its ambitious routes—such as its round-the-world jet service inaugurated in October 1959, its flashy advertising campaigns, and its reputation for good service, all made the company a leader and a trendsetter.
Jet travel revolutionized air travel throughout the world. For the airlines, jet travel forced them to establish much higher standards of maintenance that required better facilities on the ground and highly trained employees. For passengers, flights meant more comfort, less noise, and most important, less travel time. Once again, as with the introduction of piston engines into civil aviation in the 1920s, a new revolution in technology made the world an even smaller place.
