Sightseeing and Cyclones in Sacramento
On the last weekend in September, 15 DAFers assembled in Sacramento for our September Fly-In. The marine layer in Torrance forced some later-than-planned departures, but everyone was able to make the Friday night Happy Hour. Our group then wandered over to the annual Farm-to-Fork street fair that was happening just a block from our hotel. Getting hungry, most of our group met up for an impromptu dinner at the nearby Il Fornaio where we were seated in our own private dining room.
On Saturday morning, Steve Sappington made arrangements for everyone in the group to rent bikes and tour along the American River trail. The cool, partly cloudy weather was perfect for the bike ride. Everyone completed the 20 mile ride unscathed except for a couple of minor falls (although your author was seriously contemplating heading to the hospital after the ride for an emergency butt replacement).
During Happy Hour on Saturday night, just about everyone received an emergency blast on their phones. It wasn't an Amber Alert, but an alert from the National Weather Service issuing a tornado warning. That's right - a tornado alert in Sacramento! Although advised to seek shelter, the DAFers did what DAFers do - run outside to see what was happening. One part of the sky had a glowing green hue, the other part was black (except when lit up by the frequent lightning). We all walked to the nearby restaurant for our planned group dinner and seated in a covered patio right overlooking the river. Normally this would have been a perfect spot on a late September evening, but the wind and rain forced us to move to a more sheltered table (the restaurant staff was very accommodating). Following a great dinner, we went back to the hotel and enjoyed a well-deserved nightcap.
The weather on Sunday morning couldn't have been more different - a crisp but sunny fall day. Many in the group walked over to the California Railroad Museum (a great attraction), while some went over to the State Capitol and toured the grounds. And then everyone flew or drove home under sunny skies.
Thanks to Larry and Jodie for hosting the fly-in, and to Steve for arranging the bike ride.
FASCINATING ADVENTURES OF TWO BRAVE FIGHTER PILOTS OVER NORTH VIETNAM
Our September 18 dinner meeting presentation offered the dynamic duo of Col. Robert Ettinger and Col. Roy Martin who both served in the Air Force during the Vietnam War. We enjoyed hearing about the adventures they both had during their tours of duty. Col. Robert Ettinger started out the presentation by discussing the nine month period he flew F-4’s in the late 1960’s in a period of the war called Rolling Thunder. During that duty he flew 100 missions over North Vietnam. Robert shared with us about enemy ground defense, their significant number of SA-2 SAM Surface to Air Missiles (one type they called the Flying Telephone Pole), plus their heavy concentration of Anti Aircraft Artillery.
Robert also discussed our defensive tactics against the SA-2 SAM. We learned about USAF tactics along with the Alpha Strike Force timeline. Alpha Strike Force limitations included distance to targets, reliance on aerial refueling and predictable ingress/egress routes. Just introduced to the Air Force was the first terminally guided air-to-ground munition called the AGM-62 Walleye, which included a TV guided glide bomb with a 1,100 lb. shaped charge. A constant challenge included being up against numerous MiG’s which complicated things, as their primary tactic was to disrupt the Alpha Strike Force. Robert also shared with us his Ettinger’s Rules of Survival. They obviously served him well!
We then heard from Col. Roy Martin who served in Vietnam from May 1972 – May 1973 as an F-4 fighter pilot. This period of the war included the names Linebacker I and Linebacker II and had some differences in focus than the previous Rolling Thunder period in which Robert served. At this later time, there was improved laser bomb technology which included higher release altitudes and more precise targeting. There were also improved air to air tactics against MiG threats. Linebacker II included the 11 Days of Christmas (December 18-29, 1972) when peace talks fell apart and we resumed bombing of North Vietnam. The Peace Treaty was signed January 28, 1973.
It was a terrific presentation which kept the audience focused on what Robert and Roy experienced during their two distinct tours of duty during the Vietnam War. A special thank you Robert and Roy for sharing with us this important time of their lives and for their service to our country.
Flyers Down to Rio

A big thanks to Craig and Hanne Ekberg for letting us use their hangar again this year! You are gracious and generous hosts.
Also many thanks to the Hangar Potluck Committee led by Gary Palmer and Nancy Schunke, Mitch for the photo backdrop, all the setup and teardown helpers as well as those that staffed the event. We couldn’t have done it without you! And a final thank you to all that attended, you made it a night in Rio to remember!

AVIATION’S THIRD REVOLUTION: CHALLENGES AND OPPORTUNITIES

Dr. Ying presented an overview of aeronautical innovation trends and highlights that global aviation is seeing. She discussed how the challenges of aviation involve environmental issues of noise and pollutions, economic issues of cost of flight especially for fuel or energy, and the consumers need for reasonable cost and availability of flights. One of the current trends of Aviation’s Third Revolution is electric planes. There have been multiple global companies that are designing electric airplanes. Electric airplanes cost significantly less to fly, mostly due to the energy cost, electricity verses gasoline fuel. Two of the major limitations of the current electric airplanes are short duration of flight and the time needed to re-energize the airplane. Dr. Ying sees the future of electric airplanes for training and shorter commuter flights.
Ampaire has developed a hybrid electrical airplane by retrofitting a twin engine Cessna 337 Skymaster. This hybrid airplane will cut fuel cost by 50% and reduce emissions. This is Ampaire's first step into the electric airplane market. This hybrid is one of the large electrical airplanes capable of carrying additional passengers. Ampaire is currently developing a large all electric airplane capable of carrying 19 passengers.
Dr. Ying’s presentation with her extensive knowledge of aerospace, aviation, and the impact on the economy and environment was simulating to all DAFers, not just our engineering members. We look forward to news of Ampaire in the future. Thank you to Dr. Ying for giving us a better understanding of what is coming our way in the future!
