"Let's go," Rick said.

He had worked out a plan. The plane could scout the road quickly and easily. By air it was only a short distance to Bontoc, but by road it was several hours of driving because of the twists and turns. If they could spot the truck or a sedan with four men in it, they could return to Baguio and phone, and the vehicles could be held up at one of the many gates.

Scotty's thoughts were apparently the same, because Rick knew exactly what he meant when he said, "The sedan will give us trouble. We'll just have to hope that we can fly low when we see one, and try to catch a look at the people in it."

"That won't be very satisfactory," Rick said. "When we get to the airport, we'll have Angel pump those workmen some more. If they're still there. Like a pair of real meatheads, we forgot to ask for details, such as what color the sedan was."

They were fortunate. The workmen were still pecking away at the runway shoulders. And they did recall the color of the sedan. It was dark green. But they didn't know enough about cars to know the make, and they had noticed no special details.

"Have you flown before?" Rick asked Angel.

"Yes. But not in such a little plane. Only the big PAL planes."

The air-lines office was open now. Rick got his keys, arranged for gasoline, and they moved the Sky Wagon into position. There was plenty of gas for a short trip, but he was taking no chances. He wanted a full tank.

It took time to recheck the plane carefully, to make sure Nangolat had not sabotaged it. Then, finally, they were on their way. Scotty had a map spread across his knees and Angel had another. Scotty's map showed topographical details like the height of mountains and their contours. Angel had an excellent road map distributed by one of the American gasoline companies that maintained service stations in many parts of the islands.

Angel watched the roads and Scotty the mountains, and they got on the Bontoc Road with no trouble. Rick climbed until they could see for miles. It was the only way to follow the tortuous route of the road as it wound between mountains, hugged the side of high peaks, and dipped into forested valleys.
