There is some evidence that the Japanese may be using captured U.S. planes
with U.S. markings for reconnaissance purposes.
On two distinct occasions an unidentified U.S. Navy PBY has been seen hovering
around the edge of a U.S. Navy task force for a good part of the day. The Air
Officer of a U.S. carrier believes this PBY may have been captured by the Japanese
and is being used by them for reconnaissance. On an earlier occasion, a U.S. plane
tried to identify the personnel of a PBY and reported that the personnel turned
their faces away. Two other pilots reported that a PBY gave them the incorrect
signal but showed the proper lights and a third pilot said that a PBY gave him
the correct signal but showed the wrong lights. Bombing pilots reported similar
incidents where a PBY circled for a long time before giving recognition signals.
