Date & Time: August 15, 2021, 18:47 Local

Posted on Kathryn's Report
On August 15, about 1847 mountain daylight time, a Cessna 182H, N8477S, was destroyed when it was involved in an accident near Bountiful, Utah. The pilot and two passengers were fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

According to friends and family of the occupants, the airplane owner planned to take the two passengers on a local tour flight, in celebration of their one-year wedding anniversary. The owner had recently been awarded his certified flight instructor certificate (CFI), and during his training, he had received flight instruction from one of the passengers, who was also a CFI.

The airplane was serviced with 20 gallons of fuel just before departure, at about 1835. The fuel was purchased using the credit card of one of the passengers. 

The departure airport’s elevation was 4,237 ft mean sea level (msl) and located within the northern confines of the Salt Lake Valley between the Great Salt Lake and the Wasatch Mountain Range. Preliminary ADS-B data indicated that the airplane departed Skypark Airport at 1641, and after reaching the end of runway 35, began a climbing right turn to the northeast toward the foothills of the Sessions Mountains. For the next 3 minutes, the airplane continued to climb at a rate of about 700 ft per minute (fpm) and a speed of 90 knots until it reached the entrance to a canyon located about 4.5 miles northeast of their departure airport. For the first minute, the airplane remained about level with the tops of the canyon walls as the climb progressed. The airplane continued its northeast track up through the canyon, while maintaining the same climb rate into rising terrain. As the flight progressed, the height of the canyon walls began to increase such that by 1846:28, although the airplane had reached an altitude of 7,300 ft msl, it was now about 800 ft below the rims to the north and south. The airplane then entered a 1-mile-wide bowl at the end of the canyon, where for the last 8 seconds it slowed to about 64 knots and turned left to the north. The last ADS-B target was recorded at 1846:36.

The wreckage was located at an elevation of 7,225 ft, about 150 ft below and 350 ft beyond, the last ADS-B target. It came to rest facing downhill on a 50° southwest facing slope, about 1,100 ft below the summit of the surrounding canyon walls. The wreckage was within a densely forested area composed of loose shale, rock, and pine trees.

The debris field was confined within a 30 by 30 ft perimeter, at the base of a 70-ft-tall pine tree. When viewed from above, a near-vertical slash mark was observed cutting through the upper limbs of the tree, leading directly to a ground disruption and the wreckage, which was surrounded by freshly cut tree branches.

The entire cabin from the firewall through to the leading edge of the vertical stabilizer, along with both inboard wing sections was consumed by fire. The remnants of both wings were located on either side of the cabin.

Throughout the day of the accident, a forest fire had resulted in smoke and reduced visibility within the entire Salt Lake City area. The closest aviation weather observation station to the accident site was at Salt Lake City International Airport, 14 miles southwest. An aviation routine weather report was recorded at 1854, and indicated visibility of 5 miles with moderate smoke and haze.

A High-Resolution Rapid Refresh (HRRR) model sounding was created for the accident time and location, with the modeled surface elevation at 7,552 ft msl. The model indicated at that elevation, the temperature was about 22.9°C and the dewpoint was about 3.4°C, with a relative humidity of 28 percent, and wind from 307° at 7 knots. The wind remained between 7 and 12 knots through 9,000 ft msl with the wind direction from 307 to 339°. The model did not indicate any downdrafts or updrafts below 11,000 ft msl.

Tyson and Kallie Peterson
August 15, 2021

Kallie Ann Edwards Peterson was welcomed home by her Father in Heaven, along with her husband, Tyson R. Peterson, on Sunday, August 15, 2021. Kallie and Tyson left this life far sooner than anyone ever imagined, but the many people who love them can hopefully find comfort in believing that together, they are embarking on an eternal journey of joy and peace.

Kallie was born November 22, 1996 to Mark and Kori Ann Edwards in Murray, Utah. She lived in Kaysville until she was five, when her family moved to Hooper, where she grew up enjoying fresh air, drives on country roads, and a loving community. A talented dancer and tumbler, Kallie found some of her closest friends through dance and cheer, including three years cheering for the Silverwolves at Fremont High School. Her good friends helped her become a beautiful young woman, inside and out.

After high school, Kallie graduated from Utah State University with a bachelor’s degree in Aviation Technology, joining a proud line of Aggie alums. Her passion for flying led her to become a certified flight instructor for the university, and she was deeply committed to her students. She had just been hired at SkyWest Airlines with a ground school date of November 20, 2021 where she would have started her flying career with her dad in the E-175 jet. She inspired her younger sister to become a pilot as well, and they loved taking any opportunity they could to fly together.

While living in Logan, Kallie worked for Pepsi and led the Pepsi Posse, and for Lucky Slice pizzeria. As with all she did, Kallie brought her enthusiasm and hard work ethic, and came to truly love her coworkers.

In February 2019, Kallie met Tyson, and it was quickly clear he was the love of her life. Kallie’s family immediately fell in love with Tyson as well, and looked forward to the life the two would build together. After a beautiful courtship, Kallie and Tyson were married in Bountiful on August 14, 2020 and were later sealed for all eternity in the Bountiful Temple on April 21, 2021. They shared one year and one day of marriage on this earth, and their happiness and love was clear to everyone around them. Together they worked hard, laughed often, and supported one another in their goals. The life that lay ahead of them was filled with promise and joy.

Kallie was a devoted member of The Church of Jesus Christ of Latter-day Saints, and was a seminary graduate. She and Tyson attended the Foothills 1st Ward in Logan, where they enjoyed teaching the Sunbeams together.

While Kallie was full of personality and energy, with an infectious laugh and a smile that lit up any room, in her family she was the peacemaker. She had a special relationship with each family member, especially her sister Kenna and brother Danny. She loved spending time with her family, especially making beautiful memories with them on trips and enjoying special traditions together. Her grandparents, aunts, uncles and cousins were an important part of her life. Family was her priority.

She is survived by her parents, Mark and Kori Ann Edwards, her sister, McKenna Elizabeth Edwards, her brother, Daniel Mark Edwards, her grandparents, Dan and Brenda Jensen (South Ogden), her grandmother, Carole C. Edwards (Farmington), and many aunts, uncles and cousins. She is preceded in death by her grandfather, Dr. Charles B. Edwards (Farmington).

The family would like to thank the many friends and family for all their love and support during this difficult time, as well as all the dedicated search and rescue workers who responded to this tragic accident.

Funeral services for Kallie and Tyson will be held Thursday, August 26, 2021 at 11 a.m. at the Hooper Pioneer Trails Stake Center, 4979 S. 5100 W. A viewing will take place Wednesday, August 25, from 6-8 p.m. at Lindquist’s Mortuary in Roy, 3333 W. 5600 S., and Thursday at the church prior to the funeral from 9:30-10:30 a.m. Interment, Farmington Cemetery.

Tyson Ronald Peterson, 25, of Logan, UT died on August 15, 2021 in a catastrophic plane crash in the mountains east of Bountiful, UT. He was joined in death by his sweet wife, Kallie Edwards Peterson. The family is shocked and deeply saddened by this tragic event.

Tyson was born on July 24, 1996 to Ronald Brook Peterson and Jackie Carver Gold in Logan, UT. Tyson attended Chaparral High School in Parker, CO. After graduating from high school, Tyson served a mission for The Church of Jesus Christ of Latter-day Saints, serving in the Mexico, Villahermosa Mission.

Tyson was attending Utah State University, working on a business degree. He had just taken the DAT (Dental Admissions Test) and planned to attend dental school following his graduation from Utah State.

Anyone who knew Tyson, knew that he was kind, loving, intelligent, and was a child at heart. Children gravitated to him naturally as he focused on them and their happiness. He enjoyed time with friends and family. Fly fishing became a recent passion for him. Tyson’s family and friends will miss him more than words can say.

Tyson is survived by his parents, R. Brook and Mary Peterson / Jackie and Lee Gold, his siblings Jason Peterson, Brycen Gold, Kailey Gold, Taylor Gold, Mckinlee Gold, Christopher Harper, Stuart Carson, Ian Carson, and Elizabeth Carson.

A scholarship fund in Tyson and Kallie’s name is being established to honor their legacy, although details are not available at this time. Those wishing to make donations to honor Tyson and Kallie are encouraged to monitor news and social media sites for forthcoming details.

Funeral services will be held on Thursday, August 26, 2021 beginning with a Remembrance at 9:30 AM and the Funeral Service at 11:00 AM, at the Hooper Pioneer Trails Stake Center, 4979 S 5100 W, Hooper, UT 84315. The family will meet with friends Wednesday, August 25th from 6 to 8 p.m. at Lindquist’s Roy Mortuary, 3333 West 5600 South and Thursday from 9:30 to 10:30 a.m. at the Stake Center. Interment, Farmington Cemetery.

J. Parker Christensen
1992 ~ 2021 (age 28)

As a little boy, J. Parker Christensen asked his parents to change his name to "Bad to the Bone," and while his parents decided to stick with their original naming, had they agreed to the change, it would have fit Parker's personality perfectly.

Parker was born with a distinct and idyllic balance - the balance between loving his people more than life itself and living life itself to his absolute highest level of joy and fulfillment. Each dream of his moved the earth, and he ensured that his loved ones were right there in the thrill of it all. It was never 'one man for himself' - only 'leave no man behind.' Those who were in his corner were the lucky ones. Life could never be boring, could never be dull - Parker had three billion things to be eager about on any given day. Each dream was his for the taking, and he had no intention of slowing down.

Parker was the perfect big brother and took his role to heart. No one could torment his younger siblings, Sydney and Cade, better, and no one ever had their back more. His love for them was apparent to all, and not a day went by where he wasn't proud of them. Parker was always the one cheering loudest for them, no matter what they were doing. His love of nature and adventure came from his dad, Stewart, who was his idol and ski partner. His mom, Dawn, was his first true love. He could never enter or leave the room without wrapping her in his arms with one of his famous hugs. His grandparent's adored spending time with him, from joking and laughing with his Grandpa Randy, or enjoying his Grandma Connie's posole, to date nights at Market Street with his Grandma Shirley, Parker had a special connection with all of his grandparents. To his cousins, Parker was the ultimate protector. He always ensured his cousins were included in all of his crazy adventures and knew the locations of his favorite fishing spots. His cousins knew that if they had a problem, Parker would be the first one to help. Even spending time teaching a little cousin the scary story of "Click Jaw" over the phone so he wouldn't show up to summer camp unprepared.  Every aunt and uncle he leaves behind considered him one of their own, but none more so than his Uncle Josh, his mentor, a business partner, and one of his greatest friends, Josh and Parker, were inseparable in most things.

Parker was a consummate storyteller, known for telling a scary story so well; he'd keep himself up at night. And no one laughed harder at his own jokes than Park.

A life-long member of The Church of Jesus Christ of Latter-day Saints, Parker always had an enormous love for his family, friends, and country. Obtaining his Eagle Scout as a young teen was just one of his early accomplishments. 

We aren't sure if he was born with his love of our nation or having a birthday on 9/11 cemented his patriotism, but by the time Parker was in high school, he knew the path he wanted his life to take. While a senior at Bonneville High, Parker was one of the youngest applicants to gain acceptance into the Navy Seals program, and from 2011 to 2015, Parker valiantly served his nation in the US Navy. While healing from a significant leg injury during training, Parker was reassigned and became a search and rescue swimmer. As a plank owner, he was a member of the first crew and helped commission the USS Michael Murphy in New York City, October of 2012. The ship was based out of Pearl Harbor, Hawaii, and Parker was part of the ship's maiden deployment to patrol the West China Sea.

After leaving the Navy, Parker was trained and worked as a commercial deep-sea diver from Seattle to Lake Tahoe, but his true passion did not lie in the deep depths of the water but in flying the skies over the land he loved as a pilot. His favorite destinations ranged from the rivers and lakes of Montana to the desert landscape of his childhood adventures in Southern Utah, most notably Lake Powell and Zions.

Being a pilot was where Parker found his greatest joy. While working as a private and commercial pilot and founding Apache Air, Parker returned to school and was just weeks from obtaining his CFI from Utah State. Park had just negotiated with the BLM a new rural airstrip serving the communities near East Zion National Park. His military and aviation careers took him to many places around the world. He often fell in love with one place after another while fantasizing about building roots in many of the places he visited. He truly found beauty and excitement in every place he went. 

One of Parker's favorite quotes was by Leonardo Da Vinci, "Once you have tasted flight, you will forever walk the earth with your eyes turned skyward. For there you have been, and there you will always long to return." On August 15, 2021, while piloting his former flight instructor on an anniversary flight for her and her husband, Parker returned to the sky to fly high forever.

Parker trained with some of the Navy’s finest warriors, chased pirates, dove to the darkest depths, flew to the greatest heights, all while giving all of his love to his family and friends. He never missed a single opportunity to have a new adventure, chase a new goal or tell those he cared about just how much he loved them. In his almost 29 years, Parker lived more than most could dream of accomplishing in over 100. Parker was fond of saying, "If your dreams don't scare you, they aren't big enough." Parker had visions and dreams far beyond where he was. He exuded confidence and determination, always picking himself up when he was knocked down. He knew grit like no one else.

In lieu of flowers, Parker's family would request that you honor Parker by living a life worthy of his memory. Stop putting off your dreams and start chasing them. Dance in the rain while everyone else watches. Sing loudly to your favorite songs, even if no one else approves of your choice of music. As Parker wrote, "Get out, Explore, LIVE…Chase the dream, don't run out of time." Catch bigger fish, jump higher cliffs. Hug tighter, laugh louder, tell better stories. Meet more strangers, make more friends. Linger around the campfire and under the stars longer. Buy the ticket, take the ride. Go boldly.

We love you Parker. Thank you for being the inspiration we all need. You were the best of us. Fly high and rest your oars. Let's roll. 

In keeping with Parker's motto, a celebration of his life will be held on Friday, August 20, 2021 from 6 to 9 p.m. at a private residence in Farmington. Funeral Services will be on Saturday, August 21st at 11 a.m. at the Spring Canyon Ward Chapel, 6350 Combe Road, Ogden, Utah 84403. Arrangements entrusted to Lindquist’s Ogden Mortuary.
