In Plane Sight by Franklin W. Dixon

it is will have to stop, and if the person has a gun or any weapons, we can hold him.”
    â€œSounds like a plan,” Frank said. “I’d be more than happy to pay that guy back for what he put us through.”
    The brothers quickly searched the brush on either side of the road. In no time Joe located a big rotting log. The two of them hauled it out of the woods and dropped it across the dirt road. They picked up a couple of stout branches to use as weapons and took up positions on either side of the rutted track. The boys chose concealed spots close to the road. That way, when the car stopped and the shooter got out, they’d be able to jump him from behind.
    They tried not to shiver as they waited for the approaching vehicle.
    The green-and-brown four-by-four roared out of the fog. The driver spotted the big log laid across the road and skidded the vehicle to a halt. He got out to look at the blockage. The man was dressed in a tan park ranger’s uniform and hat.
    The Hardys came out of the woods and hailed the man. They held on to their sticks, since they’d never gotten a good look at the sniper. It seemed unlikely that this ranger would be the shooter, but . . .
    â€œHey!” Joe said. “Are you with the park service?”
    The driver turned, surprised to see them. The brothers noticed that he wasn’t wearing a sidearm and surreptitiously dropped their sticks. The ranger peered at them through the fog and darkness.
    â€œAre you Frank and Joe Hardy?” the man asked.
    The brothers exchanged a puzzled glance. “That’s us,” Frank said.
    The ranger smiled. “I was sent out to look for you boys,” he said, “but they told me you’d be out by Lake Kendall. How’d you get this far south?”
    â€œThat’s a long, wet story,” Frank said.
    â€œWe’d be happy to tell you once we’re in a nice, warm car, though,” Joe added.
    â€œHop in,” the ranger said. “I’ll get some blankets out of the back.”
    The brothers helped the ranger move the big log out of the road, then the three of them got into theJeep. The ranger grabbed some blankets from the back of the four-by-four. The brothers huddled together as the ranger turned up the heat inside the vehicle.
    â€œThat was pretty clever, putting that log across the road to get me to stop,” the ranger said. “You guys must be pretty resourceful. To tell you the truth, I’m surprised to find you alive. They told me that you jumped out of a plane, and one of you didn’t have a parachute.”
    â€œTwo planes, actually,” Joe said.
    â€œWe were chasing some airplane thieves,” Frank said, “but they got away.”
    â€œThey stole a plane belonging to one of our friends,” Joe added.
    â€œOut at Scott Field,” the ranger said, nodding. “I heard about that on the news. They said the plane stolen this afternoon disappeared over the park.”
    â€œHave there been any other planes that disappeared over the park before?” Frank asked.
    â€œYou mean aside from the one stolen last night?” the ranger asked. “Not that I’ve heard.”
    â€œWe were thinking of sometime earlier—this year or maybe last,” Joe explained. “Maybe even longer ago than that.”
    â€œNot that I’m aware of,” the ranger said, “and I’ve been working here for five years. Why do you ask?”
    Joe and Frank exchanged furtive glances and decided not to mention the plane under the iceat the moment. “No reason,” Frank said. “We’re just trying to see if there’s a pattern here.”
    â€œCould we use your cell phone?” Frank then asked, noting one plugged into the cigarette lighter next to the Jeep’s two-way radio.
    â€œBe my guest,” the ranger said. “The reception is pretty spotty out here, but I think we’re close enough to the relay tower for
