WHO would have thought that the ground your plane roars along during takeoff could be so spectacular from afar?

At first glance, these images look like artworks adorned with striking patterns. But they are actually airport runways around the world, captured by US designer Lauren O’Neil using Google Earth.

From Barcelona to Washington, O’Neil’s photographs offer a new perspective on runways, which are places usually perceived as quite mundane.

“I’ve found even the most humdrum cities or outdated terminals can have beautiful compositions from bird’s-eye,” O’Neil said. “Even Cleveland rocks!”

The intriguing series of images have been posted to O’Neil’s Tumblr page, calledHolding Pattern.

What a Way to Avoid Excess Baggage Charges !!!

UPON discovering their luggage was overweight, these cheeky passengers didn’t carry on. Instead, they got creative.

Traveller Stou Sandalski told news.com.au that he witnessed the duo, who were flying from Singapore to Sydney with budget airline Scoot, being informed that one of their bags was over the “free” weight limit.

Faced with an extra fee of $130, they did what many of us have been tempted to do before but dismissed as simply too ridiculous. They unzipped their bag and put on as many items of clothing as they could possibly squeeze into, until it was no longer overweight.

That included multiple hats piled on top of each other, shoes tucked into one of their waistbands and even jeans tied around their neck.

It was such a comical sight that Sandalski posted this image onto Reddit.

But according to Sandalski, there was an unexpected twist at the check-in desk.

A flight attendant said: “I am going to come to the gate and make sure you are still wearing everything”.

Oh dear.

We pity the passengers who had to sit next to them — it would have been a tight squeeze.

news.com.au has contacted Scoot for comment.

Ebola….A “Must Know” List For Travellers….A simple alert guide …

AS THE Ebola outbreak in West Africa worsens, airlines around the globe are closely monitoring the situation but have yet to make any drastic changes. Below are some key questions about the disease, what airlines are doing and how safe it is to fly.

Q: Why are airlines concerned?

A: Airlines quickly take passengers from one part of the globe to another. With some germs, one sick passenger on a plane could theoretically infect hundreds of people who are connecting to flights to dozens of other countries. Health and airline officials note, however, that Ebola only spreads through direct contact. Outbreaks of diseases that can spread through the air, such as the flu and severe acute respiratory syndrome, or SARS, are more problematic for airlines.

Q: Should people travel to West Africa?

A: The Centers for Disease Control and Prevention issued a warning last week for Americans to avoid non-essential travel to West African nations with the outbreak.

Q: Is Ebola deadly?

A: Very much so. If contracted, there is no vaccine and no specific treatment. The World Health Organization on Friday said this is the largest and longest outbreak ever recorded of Ebola. About 1,700 people have been sickened in Guinea, Liberia, Sierra Leone and Nigeria; nearly 1000 people have died.

Q: How is Ebola transmitted?

A: The virus only spreads through direct contact with the blood or fluids of an infected person, according to the CDC. It can also be spread through objects, such as needles, that have been contaminated with infected fluids. No airborne transmission has been documented.

Q: Are passengers leaving Africa being screened?

A: Since the outbreak erupted, the CDC has sent about two dozen staffers in West Africa to help try to track cases, set up emergency response operations and provide other help to control the outbreak. Last week, CDC officials said the agency will send 50 more in the next month. CDC workers in Africa also are helping to screen passengers at airports, according to CDC director Dr. Tom Frieden.

Q: Are other airports screening arriving passengers?

A: Yes. Immigration and health officials at airports as far away as India, Australia, Russia, the Philippines, Myanmar, Macedonia and elsewhere are screening passengers for signs of sickness or elevated temperatures.

Q: Do US airlines fly to West Africa?

A: Delta Air Lines flies to Dakar, Senegal; Accra, Ghana and Lagos, Nigeria. The airline also flies to Monrovia, Liberia, but for unrelated business reasons previously announced it will cancel that service at the end of September. Delta is letting passengers with flights to the region now until Aug. 15 push back travel until the end of the month. United Airlines also flies to Lagos, but has not issued any travel waiver. American Airlines does not fly to Africa.

Q: What are airlines saying about it?

A: There have been no flight cancellations in the US. All three airlines said they are in regular communication with government agencies and health officials and will follow their recommendations.

European carriers such as Air France-KLM, British Airways and Lufthansa all fly to Western Africa from their hubs in Paris, Amsterdam, London and Frankfurt.

British Airways announced Tuesday that it is suspending flights to and from Liberia and Sierra Leone until Aug. 31 “due to the deteriorating public health situation in both countries”. Passengers with tickets can request a full refund or a flight at a later date. The only other airline, so far, to cancel any flights is the Middle East airline Emirates. It has suspended its service to Conakry, Guinea, until further notice. It is still flying to Dakar.

Lufthansa notes that “there is no risk of getting infected by the Ebola virus via air circulation during flight.” Crews on Brussels Airlines flights have access to special thermoscans to check passengers’ temperature, if they feel it’s necessary. Air France has put an Ebola plan into action that includes medical protection kits and disinfectant gel available to the crew.

Passengers leaving Africa must fill out a questionnaire when entering the airport. They then have their temperature taken. They are only given a boarding pass if no symptoms are present.

: Has the airline industry dealt with any outbreaks in the past?

A: In 2003, there was a global outbreak of severe acute respiratory syndrome, or SARS. The disease was first reported in Asia but quickly spread to more than two dozen countries in North America, South America and Europe. Unlike Ebola, SARS can spread when an infected person coughs or sneezes. During the 2003 outbreak, 8,098 people worldwide became sick with SARS; 774 of those died. Airports started screening incoming passengers for fever. The disease was devastating for airlines because fearful passengers stayed home.

Fun facts about flying coming at ya.

Did you know that every day 8.3 million people are cruising the skies on some 93,500 flights? That’s about the population of NYC. Every. SINGLE. Day.

So where are most people travelling?

Our guesses were between Rio and Sao Paulo, between somewhere and Dubai and someplace in Asia. We asked the folks at FlightStats to compile data on the busiest FLIGHT routes around the world over the course of a year, and we had the gurus at FlightAware compile the busiest flight routes over the course of a single day (July 30, in this case).

From January 1, 2013 to December 31, 2013, these were the busiest flight routes around the world:

While these routes were the busiest for the entire calendar year, different routes were more popular for a SINGLE day in 2014. The busiest route for July 30, 2014 was from Seoul’s Gimpo International to Jeju International with 94 flights. The busiest route in America on July 30 was Los Angeles International to San Francisco International with 55 flights.

For the curious, the busiest route between two American cities in all of 2012 was Chicago to New York.

As the saying goes: The more you know.

“Project Jewel ” of Changi Airport Singapore …

Singapore’s Changi Airport is alreadyconsidered to be the world’s best airport. Soon, it will be even better thanks to a “lifestyle destination” addition to connect all three terminals.

Nicknamed Project Jewel, the addition will be a dome-shaped space that will house airport operations, indoor gardens, retail stores, and and hotel facilities.

Project Jewel

Changi Airport Group

Designed by the architect of Singapore’s iconic Marina Bay Sands hotel complex, Moshe Safdie, Project Jewel will bebuilt of glass and steel andshaped like a donut. It will be approximately 1.4 million square feet with five stories.

Project Jewel

Changi Airport Group

Project Jewel will connect the all three of Changi’s terminals via all-glass walkways, and will include green walls to offset the emissions from the planes overhead.

It is set to cost $1.47 billion and will be completed in 2018, according to AsiaOne.

Project Jewel

Image of the Day… Close View of Mercury !!!

Super-close views of Mercury

The MESSENGER spacecraft is now dropping closer to Mercury, and long anticipated, super-close views of the planet are beginning to come in.

Image via NASA / JHU / APL MESSENGER spacecraft

The image above is one of the highest resolution images ever returned of Mercury. MESSENGER acquired it on June 11, 2014. Last Friday – July 25, 2014 – MESSENGER’s periherm(closest point to Mercury) dropped below 100 kilometers / 62 miles. MESSSENGER is the first manmade object ever to come this close to Mercury.

On June 17 – around the time the image above was taken – the periherm had dropped to 113.80 kilometers / 70.80 miles. The image has absolutely incredible 2.90-meter resolution, showing a cluster of tiny secondary craters within the northern intercrater lava plains in a 3.00 kilometer / 1.86 mile wide area within Mercury’s North Polar Borealis Quadrangle.

The craters seen here are a few hundred meters at most in width, many much smaller. These are secondary craters from an impact out of this frame, where impact ejecta fell back on ballistic trajectories forming smaller craters. Many can be hundreds of kilometers away from the primary impact if the impact was large enough.

There are a handful of much smaller craters in the area too.

All of these craters in this image are of the simple bowl shaped type.

The image is a little ‘noisy’ due to the very short exposure required to prevent blurring of the image as MESSENGER was lower and faster than usual above the surface of Mercury.

On August 19, 2014, periherm will drop below 50 kilometers / 31 miles. On September 12, 2014, periherm will have lowered to 25 kilometers / 15.52 miles.

The number of such high resolution and even higher resolution images will increase as periherm continues to lower.

The fuel on board MESSENGER is expected to be depleted on January 21, 2015. MESSENGER is expected to impact Mercury during the last weekend of March, 2015.

Can Malaysia Airlines’ Brand Survive ?

Can Malaysia Airlines’ brand survive?

Can Malaysia Airlines salvage its brand after MH370 and MH17

 tragedies?

MALAYSIA Airlines is in uncharted territory after the disappearance of Flight MH370 in March with 239 people aboard was followed by the downing of MH17 carrying 298 people over Ukraine.

Before the disasters the carrier had among the worst financial performance of any airline. An even bigger question mark now hangs over the future of Malaysia Airlines, with its brand tied to two almost unfathomable tragedies.

Some analysts say the state-owned airline won’t survive a year without a substantial cash injection from the Malaysian government.

A bailout would address the airline’s immediate financial problems but without far-reaching changes it could remain a burden on taxpayers and shrivel into regional obscurity.

Several experts give their views on the airline’s crisis.

HOW BAD IS THE SITUATION FOR MALAYSIA AIRLINES?

Other airlines have come back from disasters but none have experienced two tragedies of such magnitude within the space of four months.

“There’s no historical precedent,” said Mohshin Aziz, aviation analyst at Maybank. “It’s completely not their fault, but right now if you ask any customers would they fly with Malaysia Airlines, they’d just have that negative sentiment of ‘I’d rather choose something else’.”

The airline was already losing about $1.6 million a day and has been in the red for the past three years. The disappearance of MH370 with many Chinese passengers on board also caused a backlash in the crucial Chinese market. Experts don’t see any short cuts to recovery.

“It cannot be a quick fix,” said Aziz. “So the second question is do they have the financial resources to survive a year, two years? And the answer is, unfortunately, no.”

IS MALAYSIA AIRLINES TO BLAME?

The airline was blasted for its erratic response to the disappearance of Flight 370 en route to Beijing from Kuala Lumpur. Because the location of the plane was unknown, Malaysia Airlines had little meaningful information for the families of passengers. Communication of what information it did have was often mishandled, compounding the anguish of relatives.

The plane, believed to have crashed far off course in the southern reaches of the Indian Ocean, still hasn’t been found.

The fate this week of Flight 17, heading to Kuala Lumpur from Amsterdam, is far more clear-cut. It was shot out of the sky over an area of Ukraine controlled by pro-Russian separatist rebels.

“They are a victim this time, so it is very different from a situation where they have no answers,” said Caroline Sapriel, managing director of CS&A, a company that specialises in reputation management in crisis situations. “The whole world is going to be sympathetic to them.”

But another narrative questions why airlines continued to fly over the conflict zone. Some airlines were avoiding it, which involves taking a longer, fuel-guzzling route, but most were not. Malaysia Airlines may face more scrutiny about its risk-management decisions once the initial shock of the tragedy dissipates.

“It is unthinkable from a risk management point of view that the plane was flying where it was,” said Kuniyoshi Shirai, crisis management expert at A.C.E. Consulting.

“Their brand is going to suffer serious damage,” he said. “There is even a possibility the airline will go out of business.”

HOW SHOULD MALAYSIA AIRLINES HANDLE THE LATEST TRAGEDY?

Clear, consistent and compassionate communications are essential, experts say.

“I think their immediate response has been consistent and caring. They are communicating on Twitter and Facebook, they are definitely going out on the commercial media,” said Sapriel of CS&A. That’s important, she said, because “if they weren’t getting the immediate response right, then it just would be the nail in the coffin for them.”

Others say that being open and transparent, continuing to assist the families of passengers and crew members while also running a punctual and reliable business will help the airline build on the sympathy about its plight.

Malaysia Airlines “appears to have learnt lessons from its halting slowness to react to the MH370 tragedy and is already applying those lessons,” said aviation consultant Robert Mann.

WHAT CAN THE AIRLINE DO TO REBUILD ITS BRAND?

The airline needs far-reaching changes.

“I think the Malaysian government is going to look at it eventually and say ‘Do we keep this same name or do we rebrand them?’ Maybe they will feel that they need a new name,” said Sapriel, the reputation management expert.

Because of its financial struggles, some analysts had advocated the sale of the state-owned airline to bring in fresh capital, ideas and expertise. Like all international airlines, Malaysia Airlines needs to renew its fleet with modern jets to be competitive, which requires substantial investment. Its capacity to make those investments is further compromised if travellers avoid the airline because of the disasters. But even a partial sale of the airline is unpopular with the airline’s union, the government and sections of the Malaysian public.

There are other ways it could make a break with the past, such as installing a new executive leadership.

“Malaysia needs to bring in a new CEO and head of flight operations to restore employee and consumer trust in the airline,” said travel consultant Henry Harteveldt of Atmosphere Research.

Beyond that, the carrier needs to demonstrate an absolute commitment to safety to overcome negative perceptions and rebuild confidence.

“You need an expert on risk management at the top, who has the power equal to a chief executive,” said Shirai, the crisis management executive.

“You have to change people’s consciousness. And while you’re doing all that, you have to keep the whole process transparent. Otherwise, you cannot regain the trust of either consumers or investors.”

Ukranian Airspace after MH 17 Incident…

On a normal travel day, the airspace over Ukraine is some of the most congested in the world. It serves as a major cross roads for flights connecting major hubs in Europe with megacities in Asia.

However, after Malaysia Airlines Flight MH17 was reportedly shot down earlier today, most of the world’s major airlines have ordered their planes to avoid the area completely.

The above map, which was tweeted by Newsweek, shows Ukranian airspace a few hours after MH17 lost contact with radar.

Two of Europe’s largest airlines, Lufthansa and British Airways, have both told Business Insider that they have ordered their planes away from the disputed region.

To avoid the Russian-Ukraine conflict altogether, Lufthansa has specifically ordered their planes to take a southerly route over Romania.

Geologic map of planet Mars

USGS released this cool geologic map of Mars this week, which was prepared for NASA. What to see first? Notice impact craters, in yellow.

USGS released this geologic map of Mars yesterday (July 14, 2015), which was prepared for NASA. If you click to the map at USGS’ site, and use the tools at the lower right, you can explore Mars. Popular Science has a good explanation of what you’ll be seeing:

All the different colored parts represent areas of crust that were formed at different times and from different processes. For example, the extensive green area near the north pole represents lowland plains formed during the Red Planet’s Hesperian Epoch, about 3.7 billion to 3 billion years ago. Scientists think those northern plains are covered in sediment from what were once Martian rivers and lakes. You can learn more about the green area, or any other colored area, in the extensive key on the right side of the map sheet.

One easy thing to spot are impact craters, which are roundish and marked on the map in bright yellow. Can you find Gale Crater, the site where NASA’s Curiosity rover landed? Gale Crater is just southwest of Elysium Planitia, which is the mostly pink area on the right side of the map.

” Why MH 17 was flying over Eastern Ukraine ? …”

 

The site of the Malaysia Airlines plane crash in eastern Ukraine.The site of the Malaysia Airlines plane crash in eastern Ukraine.

The former head of safety at Qantas has questioned whether Malaysia Airlines flight MH17 should have been flying over the eastern Ukraine given the heightened state of the conflict with Russia.

Ron Bartsch, who now heads international aviation consultancy AvLaw International, said airline network planners had a choice over whether they wanted to fly over dangerous areas or to go around them, even if it would require more fuel.

Mr Bartsch said that while bodies like the International Air Transport Association issued advisories and warnings from time to time, incidents like MH17 “really hit home that it is up to individual airlines to continually monitor and assess the risk on a daily basis”.

Ultimately it was up to the airlines themselves to determine whether potential hazards on their routes were within “an acceptable level of safety”, he said.

Mr Bartsch said there had been instances, such as a volcano eruption in Chile, when Australian airlines had chosen not to fly even though the airspace was declared safe by authorities.

“You can use the analogy of a policeman can’t be there to tell you when to cross the road and when not to,” he said. “It is up to the individual, in the case of airlines, to make that assessment.”

European air traffic control group Eurocontrol said Ukrainian authorities had closed the airspace from the ground level to 32,000 feet but the airspace at 33,000 feet, where MH17 was flying at the time it was shot down, had remained open.

Malaysia Airlines said the usual flight route was earlier declared safe by the International Civil Aviation Organisation. The International Air Transportation Association has stated that the airspace the aircraft was traversing was not subject to restrictions.

However, other airlines had chosen to avoid that airspace. Qantas said none of its flight paths track across the Ukraine and its London to Dubai services flew 400 nautical miles south of the region, having been rerouted several months ago amid the conflict between Russia and Ukraine.

Emirates said it had suspended flights from Dubai to Kiev subject to further notice, but added its flights to and from Europe and the US flew a different route outside the zone where MH17 was shot down. Cathay Pacific confirmed its flights did not fly over the concerned airspace.

Singapore Airlines would not say whether it had been flying over Ukraine until the incident occurred.

“We generally have a number of pre-existing flight paths for our flights to and from the destinations that we are operating to,” a Singapore spokeswoman said. “At this point, we are no longer using Ukrainian airspace and have re-routed all our flights to alternative flight paths that are away from the region.”

Mr Bartsch said deciding not to fly over a conflict zone such as Ukraine, Syria, Israel, Libya or Iraq would come at a commercial cost to an airline, because more fuel would be required at a time of high fuel prices.

“Obviously with airline operations now, they are increasingly commercially competitive,” he said.

“It means that unless they perceive a risk that is sufficient, they are not going to do anything other than the lowest cost route.”
