FAA initial report:

IDENTIFICATION
Regis#: 747JN Make/Model: 4M Description: SCHEMP-HIRTH
NIMBUS-4M
Date: 05/04/2008 Time: 2122

Event Type: Accident Highest Injury: Minor Mid Air: N
Missing: N
Damage: Substantial

LOCATION
City: EPHRATA State: WA Country: US

DESCRIPTION
AIRCRAFT ON TAKEOFF ROLL, WING STRUCK THE PAVEMENT AND THE AIRCRAFT
CARTWHEELED, EPHRATA, WA

In somewhat of a contradiction to the FAA report, newspaper and
eyewitness accounts state that the glider was on initial climb after
takeoff and was at 40 or 50 feet when it experienced an uncontrolled
roll. Extreme deflection of the wings on impact reportedly reduced
the damage and injuries.
