Donald Trump pulls US out of Trans-Pacific deal, loosening Asia ties

Karachi, May 25: The pilot of the Pakistan International Airlines (PIA)'s crashed plane ignored three warnings from the air traffic controllers about the aircraft's altitude and speed before the landing, saying he was satisfied and would handle the situation, according to a report on Monday.

The national flag carrier's PK-8303 tragedy on Friday, in which 97 people were killed and two miraculously survived, is one of the most catastrophic aviation disasters in the country's history.

The Airbus A-320 from Lahore to Karachi was 15 nautical miles from the Jinnah International Airport, flying at an altitude of 10,000 feet above the ground instead of 7,000 when the Air Traffic Control (ATC) issued its first warning to lower the plane's altitude, Geo News quoted an ATC report as saying.

Instead of lowering the altitude, the pilot responded by saying that he was satisfied. When only 10 nautical miles were left till the airport, the plane was at an altitude of 7,000 feet instead of 3,000 feet, it said.

The ATC issued a second warning to the pilot to lower the plane's altitude. However, the pilot responded again by stating that he was satisfied and would handle the situation, saying he was ready for landing, the report said.

The report said that the plane had enough fuel to fly for two hours and 34 minutes, while its total flying time was recorded at one hour and 33 minutes.

Pakistani investigators are trying to find out if the crash is attributable to a pilot error or a technical glitch.

According to a report prepared by the country's Civil Aviation Authority (CAA), the plane's engines had scraped the runway thrice on the pilot's first attempt to land, causing friction and sparks recorded by the experts.

When the aircraft scraped the ground on the first failed attempt at landing, the engine's oil tank and fuel pump may have been damaged and started to leak, preventing the pilot from achieving the required thrust and speed to raise the aircraft to safety, the report said.

The pilot made a decision "on his own" to undertake a "go-around" after he failed to land the first time. It was only during the go-around that the ATC was informed that landing gear was not deploying, it said.

"The pilot was directed by the air traffic controller to take the aircraft to 3,000 feet, but he managed only 1,800. When the cockpit was reminded to go for the 3,000 feet level, the first officer said 'we are trying'," the report said.

Experts said that the failure to achieve the directed height indicates that the engines were not responding. The aircraft, thereafter, tilted and crashed suddenly.

The flight crashed at the Jinnah Garden area near Model Colony in Malir on Friday afternoon, minutes before its landing in Karachi's Jinnah International Airport. Eleven people on the ground were injured.

The probe team, headed by Air Commodore Muhammad Usman Ghani, President of the Aircraft Accident and Investigation Board, is expected to submit a full report in about three months.

According to the PIA's engineering and maintenance department, the last check of the plane was done on March 21 this year and it had flown from Muscat to Lahore a day before the crash.

In the wake of the COVID-19 pandemic, the Pakistan government had allowed the limited domestic flight operations from five major airports - Islamabad, Karachi, Lahore, Peshawar and Quetta - from May 16.

After the plane tragedy, the PIA has called off its domestic operation.

Jun 25: Tencent Holdings Ltd.'s $40 billion surge this week and the recent ascent of Pinduoduo Inc. have reshuffled the ranking of China's richest people.

The country's largest game developer has surpassed Alibaba Group Holding Ltd. as Asia's most-valuable company, with its shares rising above HK$500 in intraday trading Wednesday for the first time. Pinduoduo, a Groupon-like shopping app also known as PDD, has more than doubled this year.

The rallies have propelled the wealth of their founders, with an added twist: Tencent's Pony Ma, worth $50 billion, has surpassed Jack Ma's $48 billion fortune, becoming China's richest person. And Colin Huang of PDD, whose net worth stands at $43 billion, has squeezed real estate mogul Hui Ka Yan of China Evergrande Group out of the top three earlier this year, according to the Bloomberg Billionaires Index.

The coronavirus pandemic has accelerated the digitization of the workplace and changed consumers' habits, boosting shares of many internet companies. Now tech tycoons are dominating the ranks of China's richest people. They occupy four of the top five spots: Ding Lei of Tencent peer NetEase Inc. follows China Evergrande's Hui.

‘Perform Strongly'

Tencent has come a long way since hitting a low in 2018, when China froze the approval process for new games. Since then, the stock has almost doubled, and last month the tech giant reported a 26 per cent jump in first-quarter revenue.

“Tencent's online games segment will probably perform strongly through the Covid-19 pandemic, and most of its other businesses are relatively unscathed,” said Vey-Sern Ling, a Bloomberg Intelligence analyst.

That has been a boon for Pony Ma, 48, who owns a 7 per cent stake in the company and pocketed about $757 million from selling some 14.6 million of his Tencent shares this year, data complied by Bloomberg show.

The native of China's southern Guangdong province studied computer science at Shenzhen University and was a software developer at a supplier of telecom services and products before co-founding Tencent with four others in the late 1990s. At the time, the company focused on instant-messaging services.

It has been a long comeback for Pony Ma. He overtook real estate tycoon Wang Jianlin as China's second-richest person in 2013 and topped Baidu Inc.'s Robin Li as the wealthiest in early 2014. Later that year, Alibaba went public in the U.S., catapulting Jack Ma's fortune.

Bloomberg Intelligence's Ling notes, however, that Tencent's jump this year has lagged behind some internet peers, especially those in e-commerce, games and online entertainment. Just consider: Tencent shares have climbed 31 per cent in 2020, while PDD's American depositary receipts have more than doubled. Alibaba, meanwhile, has advanced just 6.9 per cent.

May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.
