SITUATION: Mission Execution
LOCATION: In The Tunnel
TIME: 1900 hours Local Time, Current Date
In their final approach, Harvey whispered to the assembled group. "My night vision goggles, with the IFR attachment, shows me body heat from at least two guards ahead, one on each side of the tunnel. If they are facing toward us, we will have a devil of a time getting to them before they can raise the alarm. Pearly, what do your instruments tell you about motion sensors and laser beams?"
"I'm not seeing any indication of laser beams, but the motion sensors are definitely active."
"Since that is true, that means that we must stay in the middle of the tunnel on our final approach. That will make us visible to either one or both of the guards. We have to find a way to defeat the motion sensors. Any suggestions?"
Long seconds passed in the dark.
Harvey asked, "Pearly, do you have any suggestions on defeating the motion sensors?"
"Hmm. Anybody have a pair of wire clippers? If you do, we might be able to disable the sensors on one side of the tunnel."
"Aargh!" Pearly grunted. "Come on people. Give me a hand here." Silence echoed in his ears. "Oh, man. There is only one way that I can think of. If I had enough light, I could modify my instruments to send out a signal to create a cone of silence for the sensors."
"How could you do that? I thought that motion sensors detected motion."
"Actually, they don't detect motion. They send out a signal that the receptors on the sensors are on standby waiting to receive feedback from an interrupted sonic wave. If the receptor receives the same signal that the sensor is sending out, it interprets the return beam as motion. With enough light for me to see the insides of my instruments, I can rewire my detection devices to send out a cone of hyper sonic sound that would act as a baffle and would soak up the sonic waves sent out by the sensor. I would need a flashlight, but if we use a flashlight, one of the guards will probably see the light...
