## Probable cause

The loss of thermal lift during cruise flight that resulted in a forced landing.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight encounter with weather, cruise - normal
  - precautionary landing - attempted, pilot in command
  - weather condition - no thermal lift (cause)
- On ground/water collision with object, emergency landing
  - object - undetermined

## Analysis

The pilot reported that during a glider flight, the glider lost available lift.  The pilot force landed the glider in a field, short of the airport.  During the landing, the right wing impacted an unknown object and the empennage section separated from the remainder of the airframe at the tailboom.  The pilot reported no mechanical malfunctions.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
