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

The Democratic-controlled House has approved a wide-ranging defense policy bill, even as President Donald Trump renewed his threat to veto the bill unless lawmakers clamp down on social media companies he claims were biased against him during the election. Trump tweeted Tuesday he will veto “the very weak National Defense Authorization Act,″ or NDAA, unless it repeals so-called Section 230, a part of the communications code that shields Twitter, Facebook and other tech giants from content liability. Trump also wants Congress to strip out a provision of the defense bill that allows renaming of military bases that now honor Confederate leaders. The defense bill now goes to the Senate. 699

The Georgia Democratic Party and gubernatorial candidate Stacey Abrams' campaign filed a lawsuit in federal court Sunday asking for rejected absentee ballots and provisional ballots to be counted in the Georgia governor's race.The lawsuit challenges the rejection of more than 1,000 absentee ballots for missing information or mismatching information, like birth dates or addresses.The lawsuit also seeks relief for voters whose provisional ballots were rejected in Gwinnett and Dekalb counties, which are in the Atlanta metro area, because they are registered in a different county.CNN has not projected a winner in the race.Republican candidate Brian Kemp currently leads Abrams with 50.3% of the vote. If Kemp's share dips below 50%, the race automatically goes into a run-off on December 4, even if Kemp is the top vote-getter. For now, Kemp's lead stands at nearly 59,000 votes. 891

The Dow Jones Industrial Average has nearly made a full comeback from the coronavirus doldrums its faced during the spring.After peaking in February at 29,551, the Dow Jones dropped to 18,591 just a month later. On Tuesday, the Dow closed at 29,420 points for its highest close since February 12.The Dow Jones has been spurred by news that Pfizer’s Phase 3 coronavirus vaccine is showing at 90% effectiveness rating. The news has buoyed stocks from across the spectrum in recent days, including travel, technology and entertainment.After a summer of impressive gains, the Dow leveled off for much of the fall as coronavirus cases began to surge throughout the US. 671

The City of San Diego had a system in place to warn-water meter readers of inaccurate or questionable reads on manually read meters.But somehow more than 300 residents in four neighborhoods - Rancho Bernardo, Mira Mesa, Rancho Penasquitos, and Carmel Valley - were still overcharged by an average 0 on recent bills. Their meters were all the manually read type.Meanwhile, residents from Webster to Normal Heights to La Jolla are still questioning the validity of mysteriously high bills. "At this point I don't trust the government. Who is overseeing these departments?" Carmel Valley resident Denise Hornby said in a recent interview over her ,800 water bill. The city has more than 250,000 water meters that need to be read manually. Workers use a handheld electronic device to enter the readings, and get a warning if the numbers don't fall inline with that meter's use from the last billing cycle, said Steven Broyles, a city meter reader of about 18 years. "Based on the pervious use 60 days ago, it was inline," Broyles said after measuring a home in Rancho Bernardo. "So it didn't throw me a failed audit."Workers, however, are able to override the warning and enter the reading.If that happens, the city says the meter's data gets kicked into the city's quality assurance process - a process that could have uncovered the pattern of errors in those four neighborhoods. The city terminated the employee who made the errors that lead to the 300 erroneous bills. A city spokesman, however, declined to comment on whether the system lead to the discovery. The city auditory, meanwhile, is continuing a top-down probe into the water billing department. Results are expected in June.  1744
