On 14th Sept. 1983 photos of debris said to have come from KAL-007 were published in the Hokkaido Shimbun. The debris was collected near Mombetsu on northern Hokkaido. The debris clearly shows a Pratt and Whitney “Flying Pig” engine logo.
It’s called the “Flying Pig” as apparently when viewed upside down it resembles a pig instead of a stylised eagle. The issue is this logo was only used by Pratt and Whitney during the period 1982 to 1990. KAL-007’s engines were manufactured in or prior to 1972 where they carried the standard Eagle logo. The standard logo is clearly shown on all photos on file for KAL-007
ICAO reviewed maintenance records and does not mention any engine replacement. Service life show that it would be unlikely KAL-007’s engines did need replacement. This piece of debris thus could not have come from KAL-007. So it appears highly likely another aircraft was involved show how in this incident.
