An explosion rocked a chemical plant early Wednesday in Texas, causing extensive damage across the small city of Port Neches and leaving at least three employees injured.A chemical fire continues to burn at the site, and a mandatory evacuation order has been issued within a half mile of the TPC Group plant, about 90 miles east of Houston, the Nederland Volunteer Fire Department said."There's extensive damage throughout the City," Port Neches Police Department said in a statement. "Please stay off the roads anywhere near the refineries. Obey all the barricades that are in place. We are doing everything we can to keep everyone safe and informed."Personnel have been evacuated from the plant, which makes products for chemical and petroleum companies, said TPC Group, which runs the Port Neches Operations site. About 13,000 people live in Port Neches, and some said their home windows were blown out by the blast. The fire is burning a chemical called butadiene, police said. A colorless gas, butadiene is considered a health hazard, according to the US National Library of Medicine. It is made from processing petroleum and is used to make synthetic rubber and plastics."Our focus is on protecting the safety of responders and the public, and minimizing any impact to the environment," TPC Group said.The injured employees are undergoing treatment, the company said.'Then I noticed an orange glow'Tyler Shawn Dunlap was sleeping when the explosion rocked his house."I heard and felt my house shake. I first thought people were coming to break in 'cause of our intense security," he told CNN. "I went to Dad's room, and he thought our generator blew up, so we checked that, then I noticed an orange glow from the clouds."Trent Lee said the explosion sounded like a nuke and shook everything in Port Neches. The blast was also captured on Mia Hubert's 1869

As the coronavirus spread globally, a canceled work trip here and there turned into a worldwide shutdown for business travel by air.The global airline industry is now on the brink of collapse. And while pressing pause for a few days or a week is strange enough, a freeze on business-class travel that lasts for several weeks or months has the potential to reshape why people fly. After a decade of huge growth, airlines are preparing for a staggering drop in revenue worldwide. Concerns over the coronavirus have crippled demand for flights, which in turn has caused many airlines to ground their fleets and lay-off staff.Recently JetBlue CEO Robin Hayes called this financial situation for airlines, "at least as bad as 9/11 if not worse."But even with a bailout, it could take months for travelers to fully return to the skies. In the meantime, a lot of business will go on without air travel.With huge advances in telecommuting and a growing acceptance of working from home, businesses have taken to platforms like Slack, Zoom and Skype to carry on with meetings while many miles apart.To understand the impact of losing business class travel, you have to understand how valuable business class tickets are to airlines. It might just be a few seats, but on many flights, premium seats actually account for most of the money the flight will make. Let's explain.Let’s look at a roundtrip flight scheduled for the first week in August between JFK and LAX. The round trip fare for an economy passenger costs 9. For a business class passenger that seat is ,867. And finally for a first class passenger the cost is ,032. In total, if everyone pays full price for their ticket, the airline makes ,362.But notice the distribution. If you do the math, you see that although business and first class travelers only make up 28% of the passengers on the flight, they account for 60% of the flight's revenue. This model doesn't describe every flight. But when it comes to airline economics, business and first class passengers have an outsized impact on many airlines' revenue. "They care a lot about business class travelers," says airline pricing expert Andy Boyd. "The other part about the business class travelers is not just the seat but business travelers become very connected with their brand and they fly a lot. It’s not just the money they make from the one seat, but what they get over time."Boyd literally wrote the book on airline ticket pricing. He believes airlines could bounce back, but he also says the virus could accelerate some trends already in motion for business travel."It could be a catalyst," Boyd says. "But what is really interesting, the new generation has grown up with technology, with cell phones. The fact that you are doing what many older people would call, very informal communication is more and more accepted as formal communication. So as young people who have grown up with technology get older, they may find that they are just as happy doing things over the phone as they are getting on a plane and going somewhere."Those combined factors could spell long-term impacts for the airline industry beyond the spread of the coronavirus. "Normally I would tend to say we would just get over it and the world would just get back to normal," Boyd says. "But with this particular virus and the way that people have responded to it, we may see some actual real changes to the way that both business and economy travelers travel." 3474

Another person has died from an outbreak of Legionnaires' disease in North Carolina, bringing the death toll to four. None of the victims have been identified by authorities and health officials have not discussed the circumstances of their deaths.There have been 141 confirmed cases of Legionnaires' disease, an airborne lung infection, or Pontiac Fever, a milder form of the disease since last month. Health officials said nearly all of those infected were attending the NC Mountain State Fair in Fletcher between September 6 and 15.The outbreak has been linked to a hot tubs display in one events center and officials said it took place during the last five days of the fair, a preliminary report shows. In addition to the four deaths, 94 people were hospitalized. There were no other significant sources of aerosolized water -- small droplets of water or mist that can be inhaled -- at the event center, and no other ongoing potential sources of exposure identified, the health department has said.Legionnaires' disease is a lung infection contracted when people breathe in the Legionella bacteria through a mist or by accidentally getting water into their lungs that contains the bacteria.The disease is serious but can be treated with antibiotics, the department said. About 1 in 10 people who get sick from Legionnaires' disease die, a recent government report found.Legionella bacteria are found naturally in the environment but can become a health concern when they "spread in human-made water systems like hot water tanks, cooling towers of air conditioning systems, decorative fountains and hot tubs or spas that are not properly maintained," the North Carolina health department said. 1708
