a town—not a fortress, as the Huns call London. That isn't fair game for us."
But half an hour later the pilot spoke sharply, and gave an order. He pointed downward and ahead and there a faint glow, and one that spread over a considerable area, could be made out.
"That is where we are to drop the bombs," said Tom to Jack.
The other machine, which had flown somewhat behind the one in which were the two chums, now swerved over at greater speed. Her pilot, too, had picked up the objective.
And now began the most dangerous part of the mission. For it would not do to drop the bombs from too great a height. There was too much risk of missing the mark. The planes must descend, and then they would be within range of the defensive guns.
But it had to be done, and the order was given. As Jack and Tom went lower, in company with the other plane, they observed that they were over a great extent of factory buildings, where German war work was going on.
And now the noise of their motors was heard. Searchlights flashed out below them, and stray beams picked them up. Then the anti-aircraft guns began to bark.
"We're in for a hot time!" cried Jack.
