DENVER, Colorado — More than half a million students throughout the Front Range will go back to school Thursday, after more than a hundred schools and districts were forced to cancel classes Wednesday in response to a credible threat allegedly made by a Florida woman whom authorities said was 307

For Tammi Fitzgerald, being a flight attendant was an adventure. So much so, she thought she’d never want to retire from American Airlines. "I don't think there's a flight attendant out there that doesn't have a love affair with what they are doing," Fitzgerald says.But things took a turn after a strange incident in 2010. While on one flight, Fitzgerald says she smelled an unusual odor that made her sick. "My eyes were watering,” she describes. “I had a headache that was like on the front of my head, and it was just a bass drum and my nose started dripping." Fitzgerald compared the smell to the odor of moldy socks. Since then, Fitzgerald says she experienced several of what the airline industry calls "fume events.” "It's like kind of sticking and exhaust pipe out your car into your cabin and not doing anything about it," says Dr. Susan Michaelis, an aviation health and safety consultant. Michaelis, a former pilot, has a PHD in safety science. Some of her research on fume events has been published by the World Health Organization. Some experts say fume events happen because part of the air passengers breathe is pulled through the jet's engine. If it mixes with oils and chemicals and then goes into the cabin, they say it can make people sick. According to research done at Kansas State University, there are on average five fume events a day in the U.S. Judith Anderson with the Association of Flight Attendants worries it's a larger problem. "Because airlines are not required to report what are called fume events when they happen on the ground, that estimate of five or so per day is an underestimate of what's actually happening," Anderson says. Boeing disputes this, saying “cabin air is safe to breathe" and "exposure to trace levels of organophosphate contamination" is not harmful. "The initial symptoms can be flu-like symptoms, stomach cramping so you might think, ‘I’m coming down with something,’” Anderson says. “Many people report symptoms consistent with exposure to carbon monoxide gas, like headache, dizziness, fainting, disorientation, those sorts of symptoms." American Airlines told us they train crews to report fume events. Southwest says they use the modern Boeing 737, which has systems to keep the cabin safe. JetBlue didn't have an answer to our questions. Several airlines didn't respond at all. As for Fitzgerald, she says she had to take leave from her job because of fume events, and she eventually retired. Medical records show she was suffering from inhalation irritation. Fitzgerald says she’s still dealing with health issues and wants others to be aware. 2622

View this post on Instagram Excited, humble and hungry ...if there is one thing I have learned about football, it’s that nobody cares what you did last year or the year before that...you earn the trust and respect of those around through your commitment every single day. I’m starting a new football journey and thankful for the @buccaneers for giving me an opportunity to do what I love to do. I look forward to meeting all my new teammates and coaches and proving to them that they can believe and trust in me...I have always believed that well done is better than well said, so I’m gonna not gonna say much more - I’m just gonna get to work! #Year1 p.s.

A 72-year old woman was gored by a bison in Yellowstone National Park on Thursday, June 25.A news release from park officials says the tourist approached within 10 feet of a bison several times to take its photo, and the bison gored her. It happened Thursday evening at the woman's campsite at Bridge Bay Campground.Rangers provided immediate medical care to the woman who sustained numerous goring wounds. She was then flown via helicopter to Eastern Idaho Regional Medical Center.“The series of events that led to the goring suggest the bison was threatened by being repeatedly approached to within 10 feet,” said Yellowstone’s senior bison biologist, Chris Geremia. “Bison are wild animals that respond to threats by displaying aggressive behaviors like pawing the ground, snorting, bobbing their head, bellowing, and raising their tail. If that doesn’t make the threat (in this instance it was a person) move away, a threatened bison may charge. To be safe around bison, stay at least 25 yards away, move away if they approach, and run away or find cover if they charge.”This is the second incident of a bison injuring a visitor in 2020; the park re-opened several weeks ago after a prolonged COVID-19 closure.Several recent incidents involving visitors and wildlife at Yellowstone:Earlier this month, a visitor was knocked to the ground after getting too close to a bison.In July 2019, a group of about 50 people got too close to a bison, which then charged and knocked a 9-year-old girl into the air. Click here for details and video.A visitor to Yellowstone recorded in May of 2019 a small dog running around and barking at two bison .In July of 2018, a man was caught on camera taunting a bison on a road in Hayden Valley. He was later sentenced to 130 days in jail by a federal judge in Wyoming.In September of 2018, a man was knocked down by an elk while standing on the side of the road. He was not injured.Park officials say that animals in Yellowstone National Park are wild. When an animal is near a trail, boardwalk, parking lot, or in a developed area, visitors must give it space. Stay 25 yards away from all large animals – bison, elk, bighorn sheep, deer, moose, and coyotes - and at least 100 yards away from bears and wolves.The Bison is the largest mammal in North America. Males can weigh up to 2,000 pounds and stand up to six feet tall, according to the Department of Interior. This article was written by David Sherman for KRTV. 2477
