Bruce Carmichael's Barnaby Lecture topic will be "A Half Century of Soaring Technology". BRUCE CARMICHAEL 2000 Barnaby Lecturer (Details on next page) Bruce H. Carmichael was raised in the upper peninsula of Michigan, to a mining family. He was introduced to technology at a very early age. He received his Bachelors Degree in Aero Engineering from the University of Michigan in 1944. Following Naval Service in World War II, he spent over 40 years in industry, working as an applied aerospace and hydrodynamic engineer, specializing in drag reduction with emphasis on both natural and artificially stabilized laminar flow. He assisted leaders in the field such as Dr. August Raspet, Dr. Werner Pfenninger and Dr. Max Kramer. Bruce has extensive experimental experience in low and high speed flight test, low turbulence wind tunnels, water tunnels, towing basins, deep lakes, and the ocean. He served as Aerodynamics Chairman for the SSA and has been the Sailplane Homebuilders Association (SHA) President for three terms. He has published technical papers for Soaring, Swiss Aero Reiew, Technical Soaring, Sail plane Builder, Sport Aviation, Kitplanes, the TWITT Newsletter and French Experimental. Bruce participated in the transfer of laminar drag reduction technology from the sail plane community to advanced power planes. Bruce authored a unique technical book "Personal Aircraft Drag Reduction" and also one on ultralight and light self launching sail planes. He owned and flew a Schweizer 1-26 sailplane in the 1950s and 1960s. Bruce is married and has three grown children, and one grandchild. Hobbies outside of soaring include mountain hiking and aviation history.

Our Thoughts & Wishes

From: Hans Heydrick

Morgan Turner, Jeff's daughter has been undergoing a long series of life-threatening difficulties stemming from a brain tumor surgery that ran into trouble. When it rains it pours. While Morgan has been slowly getting more awake and aware, news came yesterday that her tumor has grown 50% over the last five weeks. We had been considering radiation and rehabilitation in the near term, now we must go back to surgery. Right now we are scheduled For Monday afternoon. This morning she had an angiogram to image the blood vessels in and around the tumor. Luckily, there are no more abnormal blood vessels seen in the tumor. If you will remember, bleeding from the first surgery caused most of her problems. Hopefully, armed with this information the surgeons can avoid trouble this time. Obviously, we are all extremely concerned about the risks of another surgery, but without it she cannot survive for long. I ask that you all keep Morgan in your thoughts and prayers.

Safety Corner

I have inserted 2 accident reports from the NTSB at Suggestions are always welcome!

Report 1 NTSB Identification: CHI00LA188 Accident occurred JUL-04-00 at GREGORY, MI Aircraft: Schleicher ASW-20L, registration: N4804W Injuries: 1 Minor. On July 4, 2000, at 1250 eastern daylight time, a Schleicher ASW-20L, N4804W, piloted by a private pilot, sustained substantial damage during a hard landing on runway 18 (2,450 feet by 100 feet, dry/turf) at the Richmond Field Airport (69G), Gregory, Michigan. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR Part 91 and was not on a flight plan. The pilot, the sole occupant, reported minor injuries. The flight had just departed 69G prior to the accident. According to the pilot, while flying the aero-tow he noticed that his pitch control was diminished and that the elevator control inputs were unresponsive. The pilot reported that he stayed on the aero-tow but was unable to remain clear of the tow-plane's propeller wash, and subsequently decided to release from the tow-plane, at proximately 1,000 feet above ground level (agl), on a downwind departure. Witnesses to the accident stated that the aircraft approached the airport at a high decent rate without any extended high-drag devices. The witnesses described the landing as a hard, and that the aircraft then bounced back into the air, approximately 50 feet agl, followed by a full-stop landing.

Report 2 Accident occurred JUL-29-00 at WALLER, TX Aircraft: Let L-23 SUPER BLANKIT, registration: N105LW Injuries: 1 Fatal. On July 29, 2000, at 1500 central daylight time, a LET L-23 Super Blankit non-powered glider, was destroyed when it impacted trees during the initial takeoff climb from the Skydive Houston Airport, Waller, Texas. The glider was registered to and operated by The Soaring Club of Houston, of Houston, Texas. The private pilot, who held a glider rating, sustained fatal injuries. Visual meteorological conditions prevailed for the 14 Code of Federal Regulations Part 91 personal flight, for which a flight plan was not filed. The local flight was originating at the time of the accident. According to witnesses, the glider departed and reached a height approximately 250 feet agl, when the tow-rope "broke." The glider then entered a nose high pitch attitude and "stalled." Subsequently, the glider impacted trees and the ground.

In Memory of Diane Webber

Cross Country Mentoring

Once again response has been very favorable to the XC mentoring program. Soaring XC is very alive and active in Arizona! To date we have 12 pilots for each weekend signed up as follows: Estrella on 10/7 &10/8 - Jeff Reynolds, Jim Swauger, Russ Youngblood, Mike Stringfellow, Barbara Maclean, Jim Tagliani, Tony Smolder, Nigel Cripps, Arnd Wussing, Alan Reeter, Gil Kirkpatrick, and John Weber Turf on 10/21 & 10/22 - John Goodman, Casey Lenox, Jeff Reynolds, Jim Swauger, Barbara Maclean, Mike Stringfellow, Tony Smolder, Nigel Cripps, Arnd Wussing, Alan Reeter, Gil Kirkpatrick, and John Weber

The format will be the same as the spring edition where we will have a 30 minute talk each morning by a mentor, followed by a briefing of the days weather and a suggested task. To prepare a more detailed agenda I would like to ask each mentor to e-mail me with his or her topic of discussion. The first 4 topics I receive win the daily prize of giving a 30 minute talk! What a deal! Of course it is a given that at the end of each day a thorough de-brief session will require mandatory attendance, accompanied by a wide selection of favorite beverages.

Looking forward to a great time,



1 - 26 Championships Bob von Hellens came in second in the 1-26 Championship at TSA in Jul. Region 9 Standard Class Bob von Hellens came in third at the standard class at Region 9 contest at Hobbs. 18 Meter Nationals Alan Reeter "71" came in 1st place for the day (357 miles at 87 mph) and 1st overall!!!!
