The American bombers must be in some kind of distress. He speculates that they are low on fuel, or desperately lost, or have been chased down below the cloud cover by Zeros. Whatever the reason, he knows they have not come here to attack the convoy because American bombers attack by flying overhead at a great altitude, raining down bombs. The bombs always miss because the Americans’ bombsights are so poor and the crews so inept. No, the arrival of American planes here is just one of those bizarre accidents of war; the convoy has been shielded under heavy clouds since early yesterday.
