Piedmont Airlines Flight 230Saturday August 10, 1968
Crashed on approach to Kanawha County Airport in poor visibility. The aircraft was being operated under VFR when it entered a shallow fog overlying the approach lights. Unrecognized loss of altitude orientation during the final portion of the approach into shallow, dense fog. Disorientation caused by rapid reduction in the ground guidance segment available to the pilot at a point beyond which a go-around could not be initiated.
