MARK SPENCER

Arizona State Liaison and Public Lands Liaison

Mark has lived in Arizona since 1974 and has had a long career in the Aerospace industry beginning with Sperry Flight Systems in the early 80’s. From Sperry he moved on to W.L. Gore & Associates where he was involved in microwave coaxial interconnect designs used in avionics, radar and medical devices. If you had asked Mark at age 12 what he wanted to be when he grew up he would have said “an inventor!” He is named as “Inventor” or “Co-Inventor” on 13 U.S. and European Patents so it looks like he fulfilled this dream pretty well. Mark has always been an entrepreneur owning several businesses on the side of his engineering career including an auto-body shop, photography and a small skiing and rafting tour business. In 2000 Mark ventured out completely on his own with his current business, an engineering consulting and manufacturing representative business in RF Microwave, where he is still involved heavily in the aerospace industry in Arizona and New Mexico.

Mark and his wife Stefanie are both private pilots currently living in the backcountry of southeastern Arizona near an old ghost town called Pearce. Mark and Sefanie have four grown children.

With the purchase of their Cub Crafter’s Top Cub, Mark got very excited about backcountry flying and jumped in with both feet and spearheaded the effort to add aviation to Arizona’s recreational use statute.

BILL DUGAN IS NEW NEBRASKA LIAISON

By lellington • December 21, 2025
Bill credits aviation for much of his success in business and the ability to serve his companies and family. What began in a Champ, and a Tri-Pacer owned by five people, turned into what Bill calls, “a key business tool” in which he accumulated 9,000 hours – in a Cheyenne, a Pilatus, and a TBM, where ninety-five percent of his flying was for business. “My retirement enabled me to recall ‘Why I Learned to Fly’, a slogan from an old RAF video.” Bill’s son, Patrick, purchased the C185 they now share. “While attending a business function, some associates arrived in corporate jets. As they joined up on the tarmac, the jet pilots gathered around Patrick’s 185, and one of the passengers asked, ‘What’s special about this?’ No explanation needed for this RAF audience,” Bill says. “My involvement in the RAF is, in a partial way, repaying the rewards aviation has endowed me with. Having been involved in many worthwhile nonprofits, this is one where financial support is only part of the picture. Physically participating in great projects that have a lasting effect, with good people, returns a great personal benefit,” he says. “My only regret is that I wasn’t there at the start.” Bill and his wife Jane are privileged to be able to split time between their long-time home in eastern Nebraska and Scottsdale, Arizona. While still serving on several boards, he enjoys golf “about every third shot,” biking, cars, and reading, but always looks forward to the time he can be involved in the RAF. “It’s flying with a purpose,” he adds.

RAF ADDS MICHIGAN LIAISON SCOTT ANTTILA

By Taylin Trafton • December 11, 2025
A Christmas gift of flight lessons from his parents started Scott Anttila’s aviation journey in 1985. “I learned at Johnson Field, a small grass strip tucked into the woods in Michigan’s Upper Peninsula, and that early exposure to simple backcountry flying stuck with me,” Scott says. Growing up in the U.P., he spent a lot of time outdoors and found that flying was another way to get to the places he liked to explore—especially the ones most people never saw. As he earned more ratings and eventually moved to the Detroit area for work, Scott realized he needed a way to stay connected to northern Michigan. He bought an airplane and used it to get back to the smaller airstrips and lake country he enjoyed. Along the way, he also flew gliders out of Frankfort, soaring along the Sleeping Bear Dunes and towing sailplanes over the Great Lakes. “Those flights gave me a different appreciation for the landscape and made me even more interested in the small, out-of-the-way airports scattered around the state,” he says. Visiting those kinds of places, Scott first came across the Recreational Aviation Foundation. He started using RAF-supported airstrips both inside and outside Michigan. “I noticed how well-kept they were and how much access they opened up,” he says, adding, ”Over the years, I’ve watched a number of grass strips close, which made the RAF’s mission feel especially important to me. Maintaining these airstrips keeps aviation connected to the outdoors and makes it possible for more people to reach the quiet, remote areas that inspired me to fly in the first place.” Scott joins the other two RAF Michigan Liaisons, General Grant and Tanmoy Ganguly.
