The Soaring Safety Foundation (SSF) is the Training and Safety arm of the Soaring Society of America (SSA). Our mission is to provide instructors and pilots with the tools needed to teach/learn both the stick & rudder skills and the Aeronautical Decision Making skills needed to safely fly a glider. We also provide information and analysis of incident and accident trends in order to develop better training tools.
and Scenario Database
These videos are introductory in nature and are geared to learning to soar, or a new soaring skill.
and Incident Database
These videos are safety oriented and appropriate for glider pilots of any skill level.
The Soaring Incident Database is now available to help pilots, safety officers, clubs, and commercial operators develop new programs that can help prevent incidents from becoming major accidents. See more incidents by searching the database or register a new incident.

|Incident Description||During TWO attempted launches of the Grob Twin Astir (TA), the Tost ring at the glider end released after the tow plane applied tension. After the first attempt, the front-seated pilot admitted that he might have accidentally pulled the release since his hand was near the release knob. So we tried it again...SAME RESULT...even with the pilot’s hand well away from the knob. We stopped the operation and investigated the problem. We found the AFT release knob and had somehow become lodged UNDER the aft fabric seat cushion which extends forward to the instrument panel. The knob was completely hidden from view. How it got there remains a mystery.|
|Other Comments||Apparently, the Tost release was partially opened, just enough to cause a release behind the tug even after a good pull test by the line crew. This was the third flight of the day for TA so I doubt the problem was a result of a previous maintenance action. It is speculated that the knob was pushed under the seat cushion when the aft-seated pilot got into the cockpit. A better cockpit check by the aft-seated pilot may have prevented this incident.|
