India, US should go for pre-emptive strikes, destroy Pak's N-assets: Ex-US senator

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.

Washington, Jan 10: It is “highly likely” that Iran shot down the civilian Ukrainian jetliner that crashed near Tehran late Tuesday, killing all 176 people on board, U.S., Canadian and British officials declared Thursday.

They said the fiery missile strike could well have been a mistake amid rocket launches and high tension throughout the region.

The crash came just a few hours after Iran launched a ballistic attack against Iraqi military bases housing U.S. troops in its violent confrontation with Washington over the U.S. drone strike that killed an Iranian Revolutionary Guard general. The airliner could have been mistaken for a threat, said four U.S. officials, speaking on condition of anonymity to discuss sensitive intelligence.

Canadian prime minister Justin Trudeau, whose country lost at least 63 citizens in the downing, said in Toronto: “We have intelligence from multiple sources including our allies and our own intelligence. The evidence indicates that the plane was shot down by an Iranian surface-to-air missile.”

Likewise, U.K. prime Minister Boris Johnson and Australian prime minister Scott Morrison offered similar statements. Morrison also said it appeared to be a mistake. “All of the intelligence as presented to us today does not suggest an intentional act,” he said.

The assessment that 176 people were killed as collateral damage in the Iranian-U.S. conflict cast a new pall over what had at first appeared to be a relatively calm aftermath following the U.S. military operation that killed Iranian Gen. Qassem Soleimani.

At the White House, U.S. president Donald Trump suggested he believed Iran was responsible for the shootdown and dismissed Iran's initial claim that it was a mechanical issue with the plane.

“Somebody could have made a mistake on the other side.” Trump said, noting the plane was flying in a “pretty rough neighborhood."

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.
