"Nobody likes middle seats"



VARIG was the first airline in Brazil, established on May 7, 1927 at the Porto Alegre Commercial Association meeting. It was there that Otto Ernst Meyer, a German immigrant, signed the certificate declaring VARIG an airline company.

VARIG's first aircraft was a nine-passenger Dornier Wal flying boat. Its first employee, the Hungarian Ruben Berta, later became the airline's President and led the airline until his death in 1966. The airline started operations on 15 July 1927. VARIG's first flight was from Porto Alegre to Rio Grande, stopping in Pelotas.

VARIG initially operated local services in southern Brazil, but added its first international route to Montevideo on 5 August 1942. The airline took over the REAL consortium in 1961, making it the largest airline in South America. Transatlantic services were started in February 1965, when the military government decided to shutdown Panair do Brasil, the country's flag carrier up until then. It acquired a controlling interest in Cruzeiro do Sul in June 1975, which was fully integrated into VARIG in January 1993.

VARIG had shareholdings in Nordeste Linhas Aéreas Regionais (99%), Rio Sul Serviços Aéreos Regionais (97%), and Pluna (49%). Its cargo subsidiary, VarigLog, was sold to the Volo do Brasil consortium in January 2006. Another subsidiary, VEM Maintenance & Engineering, VARIG's maintenance centre, was sold to a consortium presided by Portuguese airline TAP Portugal.

The Dornier Do J (later designated Do 15 and Do 16 by the Reich Aviation Ministry) was better known as the Wal (German for whale).

The Do J was a fairly modern (compared to World War I types) flying boat with a high-mounted strut-braced monoplane wing. Two piston engines were mounted in tandem in a nacelle above the wing and in line with the hull; one engine drove a tractor propeller and the other drove a pusher propeller. The crew of 2 to 4 rode in an open cockpit near the nose of the hull. Cabin space for up to 12 passengers was available inside the hull.

The Do J made its first flight on 6 November 1924. The flight as well as most of the production until 1932 took place in Italy because all aviation activity in Germany was forbidden after World War I under the terms of the Treaty of Versailles).

The Do J was powered by 2 Rolls-Royce Eagle IX 265 kW (355 hp) engines. with a maximum speed of 388 km/h (241 mph), and a cruising speed of 323 km/h (201 mph). Its empty weight was 2524 kg (5,565 lb), and a maximum payload of 4100 kg (9,039 lb). It had a range of 3,600 km (2,237 miles), and a ceiling of 11,480 ft (3,500 m).

The Portuguese military aviator Sarmento de Beires and his crew made the first night aerial crossing of the South Atlantic in a Dornier J named Argos. The crossing was made on the night of 17 March 1927 from Portuguese Guinea to Brazil.

Gol Linhas Aéreas Inteligentes purchase of VARIG

On March 28, 2007, Gol Linhas Aéreas Inteligentes, the parent company of budget carrier Gol Transportes Aéreos, purchased VARIG for US$320 million. Gol announced that VARIG would continue to operate under its original name. The fleet of 17 aircraft was to be increased to 34, consisting of 20 Boeing 737 and 14 Boeing 767. With the new fleet VARIG would operate to 12 international destinations: Buenos Aires, Bogotá, Caracas, Frankfurt, London, Madrid, Milan, Paris, New York, Miami, Mexico City and Santiago. VARIG's international flights would no longer have First Class, therefore consisting only of Economy Class and Business (Executive) Class. Key domestic services would be operated, including the Rio de Janeiro to São Paulo shuttle, using VARIG's 124 slots at Congonhas-São Paulo International Airport.

On June 21, 2007, Constantino de Oliveira Jr., the CEO of Gol Transportes Aéreos announced VARIG's immediate future plans for its fleet and destinations. The plan included the acquisition of nine of the more fuel efficient Boeing 737-800 model and 10 Boeing 767. Constantino also announced that the airline was in negotiations with both Boeing and Airbus for the acquisition of either Boeing 787 or Airbus A350 aircraft. The plan also included flights to Madrid, London, Paris, Milan, Rome and Mexico City by the end of 2007, and New York City and Miami in 2008. [9] In January 29, 2008, however, VARIG stated that it would end flights to Frankfurt, Rome, and London[10]. And, in April 10 the same year, the company announced it would suspend operations in Mexico City, Madrid and Paris, therefore focusing its routes network in Brazil and South America.

The present state of Varig can be seen in this list of aircraft that is currently used by the company

JetBlue founder to start new airline in Brazil

By Todd Benson

SAO PAULO (Reuters) - JetBlue Airways , founder David Neeleman unveiled plans on Thursday for a new low-cost airline in Brazil's fast-growing aviation market, saying he had already raised $150 million for the venture.

The carrier, still unnamed, will start with a fleet of three jets made by the Brazilian manufacturer Embraer and should take to the skies in early 2009. In five years, it expects to have a fleet of 76 planes.

"Brazil is a country that needs more competitors, and in particular a different type of competitor," Neeleman said in Portuguese at a news conference in Sao Paulo.

Like JetBlue, the U.S. discount carrier that Neeleman founded in 1998, the new Brazilian airline will offer low fares and use a point-to-point route structure that flies travelers from one city to another without layovers.

The new carrier will face stiff competition from TAM Linhas Aereas and Gol Linhas Aereas , which together command more than 90 percent of Brazil's domestic aviation market.

But with the Brazilian economy booming and air travel expanding annually at a double-digit pace, Neeleman is betting there is plenty of room for a new player in an enormous country where travelers have few options and where airfares tend to cost 50 percent more than they do in the United States.

"We believe airfares in Brazil are too expensive. It's time to lower prices to allow more people to fly," Neeleman said.

Neeleman said the new airline, which still needs government approval, will aim to bring affordable air travel to under-served cities outside congested hubs like Sao Paulo and Rio de Janeiro.

For its fleet, Neeleman chose the 118-seat Embraer 195, a stretched version of the roomy Embraer 190 that Jet Blue flies. The planes will be outfitted with two leather seats on each side of the aisle and live television broadcasts.

"Nobody likes middle seats," Neeleman said.

Neeleman already placed a $1.4 billion firm order for 36 of the planes, with options to buy 40 more. If all options are converted, the value of the deal could surpass $3 billion.

DISCOUNT AIRLINE PIONEER. Neeleman, 48, has a long history of shaking up the airline industry in the United States. He got his as a college student selling package tours to Hawaii before co-founding discount carrier Morris Air in 1984. In 1993, he sold Morris to Southwest Airlines for $22 million in stock. Five years later, he raised $135 million and started Jet Blue, whose electronic ticketing platform and leather seats with live TV helped redefine affordable air travel. Because he was born in Brazil, Neeleman is exempt from a law there that caps foreign ownership of domestic airlines at 20 percent. He was raised in the United States, but returned to Brazil at the age of 19 as a Mormon missionary, an experience that helped him polish his Portuguese language skills. Neeleman, a father of nine, said he is trying to persuade his wife to move the family to Brazil so he can give full attention to the new airline. For now, he plans to divide his time between Brazil and the United States. Last May, Neeleman was ousted as Jet Blue's chief executive after an embarrassing service meltdown that left thousands of passengers stranded and cost the airline more than $30 million. Since then, he has been none executive chairman, a role he said he may have to give up to focus on the Brazilian airline.

VASP (Viação Aérea São Paulo) was an airline based in São Paulo, Brazil. It had main bases at Congonhas Airport (CGH) and Guarulhos International Airport (GRU), São Paulo. The airline was established on November 4, 1933 by the state government of São Paulo and started operations in 1933. VASP was the first airline to serve the interior of the state of São Paulo. At the start of the 1930s, it was the only carrier to operate with land planes. At the time this was a real exploit due to the lack of adequate non-coastal airports. Many landing strips were improvised in flat pastures. This insistence on using only land planes led to the building in 1936 of one of the country’s most important airports, Congonhas, located in the city of São Paulo, far from the coast. During its early years, Congonhas Airport was popularly known as Campo da VASP ("VASP's [Air]field").

Although it had been remarkably well-run for most of its life as a state-owned company, by the 1980s VASP was being plagued by inefficiency, losses covered by state capital injections, and a bloated payroll for political reasons. Under the Brazilian government's neoliberal policies newly introduced at the time, VASP was privatized in 1990. A majority stake was bought by the VOE/Canhedo Group, a company formed by the Canhedo Group of Brasília and VASP employees.

Under the command of its new owner and president, Wagner Canhedo, VASP quickly expanded operations in the country, and created international routes, being the second Brazilian company to do so after 1965. However, after many years of mismanagement, financial losses, soaring debt and bad credit, in 2002 it cancelled all of its international operations to concentrate in the domestic market. By that time, VASP had plummeted from the second to the fourth position in the Brazilian airline market, flying an aged fleet of Boeing 737s (most of them of the obsolete -200 series) and Airbus A300s.

The company faced its worst crisis in 2004, which led to the suspension of service to many Brazilian cities and the cancellation of flights. As a result, VASP - once a proud, competitive airline - had its domestic market share reduced to 10%. On 27 January 2005, Brazil's then civil aviation regulator, DAC, grounded the airline from operating scheduled services pending a financial investigation. VASP was allowed to operate charter services until April 2005, giving it a chance to prove its financial stability in order to retain its air operator certificate.


As of December 2007, VASP is still not flying. The company's only activity is providing maintenance services to other airlines (in spite of all of VASP's troubles, its maintenance expertise and personnel never ceased to be held in very high regard). It has been operating under the new Brazilian bankruptcy law since July 2006, and had its recovery plan approved in 27 August 2006. VASP had planned to fly again in late 2007, but this did not happen, and there are no signs that it will happen in the near future. Services at time of closure VASP operated services to the following domestic scheduled destinations (as of January 2005): Aracaju, Belém, Brasília, Fortaleza, Foz do Iguaçu, Maceió, Manaus, Natal, Recife, Rio de Janeiro, Salvador, São Luís, São Paulo, Teresina and Porto Alegre. Services ended before closure VASP once had a much more extensive network, which covered virtually every major Brazilian city with an airport and in the 1990s included such international destinations as: Buenos Aires, Quito, Miami, New York, Los Angeles, San Francisco, Toronto, Osaka, Seoul, Casablanca, Barcelona, Brussels and Athens, Frankfurt.

Reflective surface.Paints on Glass

I suppose like most hobbies and art projects, it is first and foremost almost essential to have and interest in design, try and have reasons for liking or disliking certain designs or elements in designs, much like cooking, it is necessary to have a desire to create a flavour and work towards this end. Painting on glass is possibly a very simple process but is at its best when the glass object is part of the design or taken into consideration when planning the design, also the use to which the glass is to be subsequently put, should guide the type of paint and the design. Some acrylics are transparent, others very opaque, can be visualised through the object, or, like a plate, the glass can act as a protective screen. Working in opaque can also mean that you are working in reverse order, painting the highlights first and then working through the mid range to the background colours, no room for mistakes and needing to have the design well sorted out before hand. Transparent colours have also the difficulty of needing to have tested the colour and overlapping colours, in advance, on a trial piece of glass, the quality of the paint and the colours you choose are a factor in the final design.
Glass enamels are in actual fact ground glass with colour that is applied and then fired onto the surface of the glass object, whether in a tradition enamel kiln or with an oven that is set to maximum heat. This requires the glass base to be competitive with the paints for them to bind, the acrylic paint only requires the surface to be degreased, with alcohol or Methylated spirits.

  1. Choose the proper glass paints. There are 2 different types of glass paint- water-based and non-water based. Both have good range of colors and are intermixable within their ranges. Water based paints can be diluted with water, tools are easy to clean, drying time is 20 minutes, fully dry in 2 - 3 days.
    • Non-water based paints can be diluted with ceramic thinner, brushes can be cleaned in white spirit, drying time is 2 hours,fully dry in 8 hours.
  2. Apply the paint. When filling in areas between outlines with a brush, apply paint generously by puddling the paint or using a pipette. This will give a flat,stained glass effect. To get a lighter color paint,dilute with water for water-based paint or gloss varnish for the non-water based paints. Always pour paint into a palette rather than using straight from the jar. This prevents colors becoming dirty or diluted.
    • Sponging is another way of applying glass pain,this is good for covering large areas and blending colors while wet. The first coat can also be allowed to dry,then over sponged with a second color.
  3. Prepare the glass. Before starting to paint,remove any traces of dust and grease from the surface to ensure good adherence. Use a solvent such as white spirit or methylated spirit.
  4. Add a finishing touch. You may want to protect you solvent based paint with a coat of varnish. Glass paint varnish comes in a gloss or matte finish. The gloss varnish can be used as a colorless thinner to obtain pastel shades, without affecting the transparency and depth of color. The matte varnish gives a finish like frosted glass. To add finishing touches to a project,while painting is still wet,you can use tweezers to add beads or sequins. The wet paint will act as a glue.You an also add glitter by sprinkling it over the wet paint. Well, congrats! You have mastered the art of glass painting.

GLASS ENAMELS

Although traditional painting on stained glass is probably the most common way of painting on glass, painting with glass enamels has grown significantly in popularity the last few years. The range of colors is extensive, and the ability to mix colors means that a virtually unlimited palette is available.

These "paints," which like traditional stained glass paints are actually finely ground glass particles with a relatively low melting point, are available in both transparent and opaque colors. They are applied, then fired onto the glass using a kiln.

Because glass enamels are made of tiny glass particles, care must be taken to ensure that they are compatible with the base glass being painted on. As with any other glass, using incompatible enamel will result in cracking or poor adhesion.

Care must also be taken when using glass enamels that the fine particles are not inhaled. A respirator or mask is recommended to prevent this, as inhaling fine glass particles can cause silicosis, a serious and potentially fatal lung condition.

There are a number of ways in which glass enamels may be applied, but in most cases the enamels are applied and fired in several layers. This maintains the integrity of the colors and also helps to achieve effects that would not be possible in a single firing. It is not uncommon for enamels to require four or five or more firings before the work is complete.

BRUSH APPLICATION

To apply enamels with a brush, you must first mix the glass particles with a liquid (called a "medium") to obtain a paint-like consistency. Mediums may be oil or water-based, but water-based mediums have the advantage of generally being safer and easier to clean up. The key criterion is that the medium fires clear without leaving a residue. Commercial preparations are available, but good results have been reported from using substances as common as 7-UP (or Sprite, if you prefer).

The proper consistency for painting is approximately one part enamel to two parts medium, but this can vary depending on the particular enamels used. It's a good idea to mix the paints on a smooth surface (a sheet of window glass is ideal), adding the water drop by drop until the desired consistency is reached. Sometimes the paint will dry out a bit during painting and you will need to add a few extra drops of water.

Any brush may be used, but recognize that transparent enamels tend to show brush marks. Take advantage of this by using the brush to create desirable patterns and textures. (Opaque enamels are less likely to exhibit this trait.)

Once application is complete, the enamels should be allowed to dry prior to being kiln-fired. Enamels will mature at various temperatures, with opaques generally requiring higher temperatures (around 1450 degrees Fahrenheit) and transparents needing only to be fired to around 1200 degrees F. For enamels that fire at this lower temperature, it is possible to both slump and fire on enamels in the same firing. Many of these lower-firing enamels contain lead, so care should be taken not to use them on food-bearing surfaces.

It's possible to achieve significantly different results by varying the method of brush application. The enamels can be mixed very thin and splattered onto the glass a la Jackson Pollock. They can be applied, allowed to dry, then scratched partially off to yield interesting patterns. Often, the best results come from very thin applications and multiple firings; thicker applications tend to result in a dark, muddy appearance.

Also, many glass artists use "reverse painting" techniques. This approach, which is contrary to "normal" painting techniques which start with the background and add details as a final step, starts on the backside of the sheet of glass. Working from the top layers to the bottom, successive layers of paint are added and fired until the picture is complete. Although the approach appears strange at first, it results in a work with an exceptionally clear and glossy surface.

Remember that when firing enamels you must follow the normal warm glass procedures to heat, anneal, and cool the glass to prevent cracking and thermal shock. Fired properly, the enamels will bond to the glass, resulting in a permanent, lustrous finish.

DRY APPLICATION

Glass enamels can also be applied dry. To do this, simply place a small amount of enamel powder in a sifter and sift. You can add interest by drawing patterns in the sifted powder or masking off a portion of the glass "canvas" to control where the powder goes.

If you work with glass enamels, it's a good idea to wear a mask to keep from inhaling the glass particles. This is especially good advice if you are sifting and working with dry enamels, which can easily become airborne.

Glass Types and Forms

In addition to compatibility, glass artists also differentiate among different types of glass in many different ways. One of the major criteria for differentiation is the transparency of the glass. Opaque glasses that do not transmit light are generally referred to as "opaques", as "opalescent" glasses, or as "opals." See-through glasses of various colors are usually called "transparent" or "cathedral" glasses. Combining more than one different opalescent or cathedral glass or color in a single kiln-formed work is common.

Several different companies offer lines of tested compatible glass, with the largest and most popular being Bullseye and Spectrum. Other companies offering tested compatible glass include Uroboros, Effetre (Moretti), Wasser, and Gaffer.

Bullseye, which has produced tested compatible glass since the 1970's, is generally acknowledged as the market leader, with a broader product offering than Spectrum or other brands. Spectrum's tested compatible program, initially launched in Spring 2000, contained glasses made by both Spectrum and Uroboros, and is marketed under the "System 96" name. Although the two product lines behave similarly in the kiln, they are not compatible, so most glass artists and hobbyists choose one or the other brand as their primary glass for fusing and slumping.

It should be noted that Bullseye, Spectrum, Uroboros, and many other firms also manufacture glass that is not guaranteed compatible. (A complete list would also include companies such as Armstrong, Desag, Freemont, GNA, Kokomo, Wissmach, and Youghiogheny. Sometimes the glasses made by these companies tests compatible for fusing, but often it does not. If you wish to use any of these glasses for kiln-forming projects involving more than a single sheet of glass, you will need to test for compatibility.

Virtually any stained glass, whether tested compatible or not, can be treated with an iridescent coating that causes the treated side of the glass to take on a metallic sheen. Some liken this effect to a shimmering rainbow. The shimmer goes away when the piece is lit from behind, allowing the normal color of the glass to shine through.

Another popular kind of glass coating, called "dichroic", has the unusual property of reflecting one color while it transmits another. This means that the different colors can be viewed by examining the glass at different angles. This unique glass is manufactured by spraying a thin chemical film on the glass. This must be done in a controlled environment in a vacuum chamber, making dichroic glass one of the most expensive glasses made for kiln-forming. Because of this expense, dichroic glass is more commonly used in jewelry and similar items, or as an accent in larger scale fusing projects.

One final type of glass that is often used for kiln-forming is "float" glass. Made by "floating" molten glass on a bath of molten tin, float glass is better known as common window glass. It is inexpensive and widely available. It also works well in the kiln, but care should be taken to test for compatibility if different brands and types of float glass are mixed together. If at all possible, cut pieces to be fused together from the same glass sheet.

Although some colored varieties of float glass are available, it is most commonly found in a clear (often slightly greenish) formulation. It tends to slump and fuse at slightly higher temperatures than most art glass (about 75 to 100 degrees F higher), and can be prone to devitrification. Its COE depends on the specific formulation used and can be as low as 83 or as high as 90, but it generally ranges from 85 to 87.
