A Japanese method in bombing operations is to send a fleet of bombers over the objective
and drop no bombs at all. However, these are followed within a short period, from ten to
fifteen minutes, by another fleet of bombers which do all the damage.
The Japanese also employ a method known as the "hidden fighter." This consists of an
attack by a group of bombers which brings the British planes into the air. Then all but
one of the Japanese bombers leave. The remaining bomber lurks in the vicinity behind hills
until sufficient time has passed to allow the British fighters to land at their airfield, at
which time the Japanese bomber comes out of the shadows and destroys the British planes on
the ground. This deceptive method was used very effectively in Singapore, not only in the
destruction of buildings but in causing great casualties among the people.
In a recent raid on Port Moresby, five Japanese fighters arrived 90 seconds prior to the
appearance of bombers and traced a cross of white smoke. When the bombers appeared, they
flew through the center of the smoke pattern and released their bombs
approximately 12 seconds afterward.
