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.

Sometimes one needs to look no further than one's incoming correspondence to find inspiration. Just this past week, folks passionate about the RAF mission reached out to me with suggestions that would bring resources to the RAF. Whether they be one-off items that we might offer, or events like large fundraisers, these folks are offering some thoughts on how we might continue to pay the bills. Additionally, we’re receiving word from folks with new destinations on their mind, and some pretty cool ones at that. Along the way, my inbox – as well as my calendar – is filled with updates on our Expanding the Map effort, with an emphasis on Fly Rocky Top. The Fly Rocky Top initiative in Tennessee is generating strong interest, and for good reason. It feels great. Folks are showing up to pitch in, with significant work projects planned. Trish and I, along with other board members, will be there to lend a hand to this exciting project. We are coming up on our annual year-end letter, which you will be seeing not long from now. In addition to showcasing a few more of our successful projects, we will be seeking your support. Stand by. I’ll wrap this up by letting you know that we could not be more pleased with how you all are doing your part. Thank you. It is so healthy to have an organization that uses passion as a primary energy source. - John McKenna, RAF Chairman Submitted September 14, 2026

“We had a busy day at Garrison Dam Recreational Airpark, as we continue to work on the underwing camping area,” RAF North Dakota Liaison Brian Rau reported. Rau was awarded an RAF grant in spring of 2026 to convert an adjacent day-use park into an airport camping area, and had organized volunteers who began the project in May. The airport, 37N, is closed while the runway and taxiway are being upgraded by a contractor for the ND Aeronautics Commission.

You know the feeling. You set the airplane down somewhere spectacular, shut off the engine, and enjoy the pristine landscape in front of you. This is why you fly. Keeping airstrips pristine is everyone's responsibility. But one item that doesn’t always make it into the airplane is a good trash bag. Not for the trash you planned to make. For the trash you didn’t. Cans left in a fire ring, fishing line along the river, or food wrappers working their way through the brush. None of it came in your airplane, but you have the ability to get it out. That’s reason enough to tuck a couple of heavy-duty contractor bags in with your tie-down gear. They earn their space in other ways, too. A contractor bag can keep wet or muddy gear out of the baggage compartment, cover equipment in a downpour, collect rainwater, or become an emergency poncho or windbreak. It weighs almost nothing and takes up very little room. Throw a few in the airplane and leave them there. You may not need one for your own trash, but there is a good chance you’ll find another use for it—or find something worth carrying out.
