SLSPA member Steele Lipe gave a talk on the use of oxygen. Stan Nelson, SLSPA's new President gave a talk on flying self-launch sailplanes safely. At the SLSPA Breakfast over 77 people were present, including 40 SLSPA members. At this breakfast, Stan presented Pete Williams with a plaque of appreciation for his tenure as founder and president of SLSPA over the past seven years. John Schmidt, Stan Nelson and Pete Williams met with Gene Hammond, SSA's Soaring Safety Foundation chairman to review the FAA A.C. 61-94 covering the recommended training procedures for transition to self-launching sailplanes. John Schmidt, SLSPA's Safety Chairman will be reviewing this A.C. with input from Williams, Nelson and Tom Knauff. The objective being to assist FAA in updating this document with SSA input to preserve the intent of the A.C. to not establish a powered glider rating.
