ATHENS, Oct 14 (AFP) - Four Greek air force members were feared dead after debris of a Greek F-16 fighter jet was found in central Greece, while another one was missing.
Debris of one jet was found on a slope at Mount Pilio, central Greece, according to air force spokesman Constantinos Prionas.
Authorities have received no sign of life from the two planes` crews, and it was still unclear whether they ejected to safety.
Three military helicopters were combing the area for survivors.
The fully manned two-seater planes departed for a training flight from the Larissa military airport in central Greece and disappeared from radar screens over Pilio at around 3:00 pm (1200 GMT).
Crashes are relatively frequent in the Greek air force. The country`s air force chief of staff was sacked in September following the crash of a military helicopter that killed the Greek Orthodox Patriarch of Alexandria and 16 others, including priests and military crew members.
A Mirage 2000 warplane crashed in the Aegean sea in a training flight in September, but the pilot escaped injuries by ejecting to safety.
In November 2003, another military aircraft of the same type on a training flight crashed into the Aegean, while a month earlier an A-7 Corsair went down in southwestern Greece after mechanical failure. Its pilots escaped unharmed.
