After an interval of a fortnight, the Germans resumed their
day- light air raids early last Sunday morning. A squadron estimated at from fifteen to twenty-one aeroplanes attacked Felixstowe and Harwich. At Felixstowe the raid only lasted a few- minutes ; the material damage was slight, but thirteen persons were killed and twenty-six wounded by bombs. No casualties were reported from Harwich; the raiders were driven off, and one of them was brought down at sea on the return journey. Warnings weregiven in London. People were roused from bed or breakfast by the sound of explosions. and believed themselves to be in the middle of a raid. Fortunately. as it was Sunday, there was not much business to be interrupted by these warnings of a raid that was nowhere near London. The Home Secretary has admitted that " inconvenience " was caused. He agreed that in future the warning must be delayed until the enemy aircraft camenearer, and that the number of signals might well be reduced. The great objection to the soand.bomb is that it is almost indistinguishable from the real thing. If sound in to be effective as a warning, it should be of a wholly different quality from that of the bomb that falls from the skies.
