F-16 engine damage
BRUSSELS (AP) -- A senior Western diplomat says several NATO F-16 fighters suffered engine damage after flying through the volcanic ash cloud covering large parts of Europe.
The official declined to provide more details on the military flights, except to say that glasslike deposits were found inside the planes' engines after they patroled over European airspace.
