The aircraft stood overnight in the open at the station airstrip ready for an early morning take off. In a
daily inspection made soon after first light, the pilot found that a heavy dew had left beads of moisture
covering the aircraft exterior. This was cleaned off the windscreen, which was also misting internally.
After a normal warm up and ground test the pilot cleaned the inside of the windscreen and lined up for
take off. At this time forward vision was somewhat obscured but the pilot anticipated that outside
condensation would clear as the aircraft gathered speed. The take off was commenced but the pilot found
that the windscreen did not clear as expected and when full power had been applied and at a speed of about
50 knots, moisture blowing back off the nose of the aircraft caused almost complete loss of forward vision.
Finding that the aircraft was moving to the left side of the strip the pilot closed both throttles to abandon the
take off and attempted to brake to the right but was too late to prevent the aircraft from swinging left off
the strip. The wings were damaged by impact with small trees and the aircraft groundlooped to the right and
skidded to a halt. The passengers left by the normal exit and there was no fire.
