The Federal Aviation Administration has issued a safety alert about flying with dry ice onboard, in anticipation of the huge nationwide distribution project anticipated to start in the next few days once the Pfizer COVID-19 vaccine is approved for use.The Pfizer and Moderna vaccines both need to be kept at extremely cold temperatures, requiring the use of dry ice during transit.Dry ice is frozen carbon dioxide that is pressed into blocks or pellets. It doesn’t melt into a liquid, it moves directly from a solid to a gas and that process can happen quickly at high altitudes.That can cause problems onboard a plane, such as causing the plane to weigh less at times during the flight and change its center of gravity.“CO2 sensors installed or carried in the aircraft or worn by the pilots and other crewmembers will assist the operator and crew in recognizing hazardous concentrations of CO2 and implementing effective risk controls,” the FAA’s safety alert recommends.In addition, they encourage maximum ventilation onboard while on the ground and in the air, asking crewmembers to check air conditioning units and auxiliary power units before flight.Exposure to elevated levels of CO2 can cause drowsiness or dizziness, and higher levels can impact breathing eventually leading to hypoxia and death.The FAA also recommends that “pilot training on specific conditions and procedures can improve pilot decision-making in the event of a CO2 detector alert or other system abnormalities.”Friday morning, Health and Human Services Director Alex Azar said Americans could begin getting the COVID-19 vaccine next week once the FDA and CDC give it emergency use approval. 1676

No injuries are reported."Scanning machines at the facilities detected the suspicious materials upon receipt and the packages are being examined at the FBI lab in Quantico, Virginia, the law enforcement official said.The National Defense University at Fort McNair was cleared for re-entry after K-9 sweep and personnel returned to the building by 1:15 pm ET.Another Army spokesman confirmed a suspicious package incident at Fort Belvoir and said that package has been rendered safe. 1296

The COVID-19 pandemic is putting vacations on hold across the country. Luckily, Airbnb Experiences is offering a getaway that doesn't require leaving the house.The new program offers worldly activities with chefs, fitness trainers and other experts from various fields.Like coffee? Take a coffee lesson from a national judge. Need to relax? Try meditation, "guided with sleepy sheep." Or, learn how to meditate with a Buddhist Monk.There's yoga, wine tasting and cooking classes — but the dogs of Chernobyl experience is getting the most attention. The experience, guided by a Ukrainian native, introduces users to the dogs of Chernobyl — the second- and third-generation of wild dogs who were in the region when the nuclear disaster took place.It's been a rough year for Airbnb. In a business reliant on travel, COVID-19 was a huge hit for the company."When you're in travel and tourism and you get hit with a global pandemic there is no necessary playbook for that," said Chris Lehane, the Senior Vice President for Policy and Communications at Airbnb.But Airbnb has adapted. They've realized that people still need a way to escape while stuck at home.Airbnb has also seen a rise in customers traveling to rural areas within driving distance."Sixty percent of traveling in Airbnb is within 300 miles of where someone lives," Lehane said. "I say this as a father of two teenage boys — people are looking to get in their car and drive without stopping."Airbnb says one of its top "trending" destinations is southwest Michigan. Hannah Heyn and her family rent out four different places in Sawyer, Michigan on Airbnb."It's very special in the sense that there's a lot of breweries, wineries, beaches, trails," Heyn said, "It's a little treasure in our Midwest area, and when you love your area, you want to share it with others. And we love doing that."Airbnb is their primary source of income, and they're just now coming back from the rough stay-at-home spring. Now Heyn is booked through August, and the "Superhost" is learning new things about the place she calls home."We had a guy coming to learn how to make better and fancier chocolates, and I didn't know we had that," she said. "He was meeting with a top chef here to learn how to make delicate designs on chocolate."Airbnb has also introduced an "Enhanced Clean" option, which Lehane says gives hosts more control over their environments and allows vacationers to feel more comfortable."The protocol includes the types of equipment to use when cleaning, the type of chemicals you should use...really explaining and educating and providing protocol about the difference between cleaning, picking up clutter and dust-and-sanitizing," Lehane said. 2711
