"The men found in it are killed," continued Hal "'killed by the shrapnel fire—also, of course, they burn with the aeroplane. It is, to all observers, a bombing biplane shot down in flames."
"And you think such a plan will succeed?" asked the captain.
"I feel sure of it, sir."
"Well," said Captain O'Neill, "you are the two who must take the chances. You have my permission to adopt your own plans."
CHAPTER XXVIII
OVER THE LINES
"You will carry these with you, of course," said Captain O'Neill, "those who will be found in, the plane?"
"Yes, sir," said Hal. "They need not be aviators, but merely in uniform."
"You drop from the machine as she strikes, I suppose?" said the captain. "She will run after that, of course."
"Certainly it will leave us unsuspected," said Chester. "It will aid our escape. Certainly no one would suspect a man had planned to fall in flames."
