“We’ll take Scottie’s plane!” Mary exclaimed. “It’s gassed and oiled, ammunition, everything. I helped him get it in shape last night. It’s really fast and a real fighter!”

“Come on, then!” Once again Sparky led the way.

“All right, Mary,” he called. “Not much time. What about your jacket, oxygen mask, and all that?”

“They’re all here. Scottie’s are there, too, for you. We left them. I—I don’t know why.”

“That’s great! Get in and let’s ramble. Okay, boys, turn us loose!”
