The United States National Transportation Safety Board (NTSB) has completed its investigation into the ditching of US Airways Flight 1549 into New York’s Hudson River. The fifteen-month probe began after the Airbus A320 performed a water landing when bird strikes damaged both engines in a move dubbed the “Miracle on the Hudson” by the media. Nobody was killed.

The NTSB’s final report, adopted after a board meeting today, concluded that a combination of safety equipment better than the mandatory minimums and good reactions by the crew were the main reasons the 150 passengers and five crew survived. The board stated that the aircraft’s equipment met the standards required for “extended overwater operations”, equipment that was not needed for the January 2009 flight.

The aircraft was equiped with escape slides that doubled as water rafts at the front and aft emergency exits, but the aft ones were rendered unavailable. Airbus assumed when designing the aircraft that only one engine would be inoperative during an emergency ditching, and current emergency checklists assume plenty of prior warning for dual-engine failure since the aircraft would be at a high altitude. The A320 was at just 2,700 feet when the incident occurred, having just taken off when it collided with a flock of Canada geese, almost completely removing the engines’ ability to generate thrust.

The final report has blamed a number of factors for extensive fuselage damage caused in the impact, which cracked a rear bulkhead and caused the aircraft to flood, as well as taking the rear slides out of action. The board said standards aircraft should meet in ditchings — set by the Federal Aviation Authority (FAA) — were inadequate, training in industry was not sufficient for ditchings and the high level of tasks the crew had to focus on made it difficult for the pilot to maintain his airspeed. The pilot’s decision to ditch was credited as being the best possible solution to the emergency.

The NTSB noted that while the rear rafts failed, 64 people climbed into the forward rafts, and said many of these people would have been immersed in the frigid river. The board claimed that this could induce “cold shock”, which can lead to drowning within minutes.

The report found that the good visibility, calm water, nearby ferries which provided rescues within twenty minutes and good cockpit resource management, allowing the crew to maintain control, were further factors that contributed to the survival of those on board. However, it also found that “more creative and effective methods of conveying safety information to passengers” are required after learning that most passengers had not paid attention to the in-flight safety announcement. It also noted that many passengers had difficulty putting on the life vests supplied under the seats.

The report further stated that the accident was hard to predict due to the fact that bird strikes tend to occur much lower, usually below 500 feet. It considered the possibilities of fitting engine screens or redesigning engines to mitigate bird strike risk, but these proposals were rejected after consideration since they were deemed unfeasable.

NTSB Chairman Deborah A.P. Hersman described the circumstances as “a great example of the professionalism of the crewmembers, air traffic controllers and emergency responders who all played a role in preserving the safety of everyone aboard.” She further discussed the safety recommendations the report will contain when it is released. “I believe the safety recommendations that have come out of this investigation have an extraordinary origin – a very serious accident in which everyone survived. Even in an accident where everyone survives, there are lessons learned and areas that could use improvement. Our report today takes these lessons learned so that, if our recommendations are implemented, every passenger and crewmember may have the opportunity to benefit from the advances in safety.” A total of 35 recommendations have been made seeking improved checklists for emergencies, better certification standards for aircraft and their engines, advances in crew training, better safety equipment and improved safety briefings to passengers.

One result of these findings is that the board will likely ask the FAA to require emergency equipment for water landings on all commercial aircraft. The FAA has until now held that such a move would place a disproportionately high cost on airlines.

A six-pound infant born in San Francisco, California has six perfectly formed and functional fingers and toes on his hands and feet, so that it isn’t considered a disability or deformity, say doctors at Saint Luke’s Hospital who were amazed by the oddity.

In a medical rarity, super baby Kamani Hubbard was born two weeks ago with 24 working digits. He is healthy and home with his parents in Daly City, California. Polydactyly, a congenital disorder is not uncommon in humans and animals, including cats, but to happen on both hands and feet is a rare hereditary condition.

“Nurses and doctors, looked so normal they couldn’t tell, they told me he was six pounds in good health, that was all they said,” said Miryoki Gross, Hubbard’s mother. Her baby’s specialness didn’t even show up on prenatal ultrasounds. “I heard nothing before I gave birth so I’m still in shock, kinda,” Gross added. Despite the mother’s shock, Kamani’s father, Kris, was the first to notice the condition.

Polydactyly (from Ancient Greek means ‘?????’ (polus) or “many” + ‘????????’ (daktulos) “finger[s]”), also known as polydactylism, sexdactyly, hexadactyly, or hexadactylism, is a congenital physical disorder consisting of supernumerary fingers or toes.

In Kamani’s case, however, all of the digits are perfectly formed and function or work normally. “I was in amazement, it took a little time for me to take it all in,” said Kris, a postal worker, who has a family history of polydactylism, but none of his relatives can remember it happening on both hands and feet.

Mostly, cases of polydactyly are surgically corrected. Kris himself had nubs of sixth digits, which were removed during his early childhood, for having been non-functional. “My son has six fingers then I saw toes, and I thought, this is quite unique. Some family members have had six fingers, not completely developed. But not the toes,” Kris noted.

“I would be tempted to leave those fingers in place. I realize children would tease each other over the slightest things, and having extra digits on each hand is more than slight. But imagine what sort of a pianist a 12-fingered person would be imagine what sort of a flamenco guitarist, if nothing else think of their typing skills,” Dr. Treece remarked.

“I just want him to see what greatness will be in store for him,” said Kris.

Fully developed and functional extra digits on both hands and feet are considered very rare as a genetic trait in medical history, amid some partial development of an extra digit occurs about twice in every 1,000 white male births. Ordinarily, polydactylism appears as an extra piece of non-functional tissue, typically occurring as an extra finger, sometimes with a bone, but no joint.

“It’s merely an interesting and beautiful variation rather than a worrisome thing,” said Dr. Michael Treece, a St. Luke’s Hospital pediatrician, and the OBGYN who delivered Kamani. He has postaxial polydactyly, which is 10 times more likely to occur in black children, and also more likely to appear in boys.

Goliath, a figure in Old Testament, was depicted as having had six fingers on each hand and six toes on each foot.

Blues guitarist Hound Dog Taylor, Get Carter, Little Tich, Toyotomi Hideyoshi and several other figures in history have had polydactyly. Sid Wilson, a turntablist of Slipknot, had been born with an extra finger and toe on his hands and feet which were removed shortly after his birth as doctors considered them to be dead.

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

Yesterday, NASA announced their spacecraft Juno has reached Jupiter orbit. It was launched almost five years ago to investigate the largest planet of the Solar System, especially its past.

Charles Bolden, NASA administrator, said, “Independence Day always is something to celebrate, but today we can add to America’s birthday another reason to cheer — Juno is at Jupiter”. He also added the spacecraft would help study the evolution of the Solar System and explore Jupiter’s radiation belts.

NASA spent US$1.1 billion for Juno. The Jet Propulsion Laboratory (JPL) reported Juno was confirmed in Jupiter’s orbit at 0353 UTC. Including the camera, the probe has nine scientific instruments. Juno has covered 2.7 billion kilometres (1.7 billion miles) to reach Jupiter.

NASA said non-essential equipment was turned off for the approach. They expect photos in some days. The first orbital revolution period is 53 days. Juno is expected to orbit the planet 37 times keeping an altitude of 5000 kilometres (3100 miles) above the Jovian clouds and then fall into the planet in 2018.

NASA’s Galileo, launched in 1989, found evidence of saline water on Jovian satellites Europa, Ganymede, and Callisto.

The electronics have been encased in titanium to protect them from high-energy radiation.

Visibly relieved and sobbing as the verdict was read, Robert Blake was acquitted on all counts and walked out of the courtroom yesterday a free man.

Charged with murdering his wife, the jury acquitted Blake due to lack of evidence. He was also charged with two counts of soliciting to have his wife Bonnie Lee Bakley killed. The jury acquitted him on one count, and the judge dismissed the second after the jury became deadlocked in an 11-1 vote.

He was greeted by a crowd of cheering supporters outside the courthouse. The star of the television series Baretta crushed out one of his trademark cigarettes and spoke to the gathering, thanking his lawyers and private investigators who he described as, “This small band of dedicated warriors that saved my life.”

In a speech that lasted 30 minutes, he talked of having to spend $10 million for his defense and said that he was now a poor man who needed a job. The 71 year-old actor also said he was ready to “cowboy it…Get in a motor home or van, feel the wind in my hair and find a little bar in Arizona or someplace.”

The prosecution, which did not seek the death penalty, painted Blake as caught in a loveless marriage with Bakley. Tricked into marrying her by his love of their daughter Rosie, now 4, they claimed that he had felt trapped by a woman who had a history of being a low-life grifter. They alleged that Blake, frustrated after trying to find someone to kill his wife for him, killed her himself. They also claimed that he was the trigger man who, after dining with his wife in their favorite restaurant, put two bullets in her head as the two of them sat in their car outside.

The jury foreman in the trial, Thomas Nicholson, described the prosecution case against Blake as “flimsy.” He said “they could never connect all the links in the chain. We couldn’t put the gun in his hand.” Blake’s defense team was also able to successfully discredit witnesses who testified on the solicitation charges.
