Chapter 732: Bomb Disposal (Part 1)
"OK, whether it's Clay, Jack, or Jim (Aubrey), strictly speaking, I can't force you to stay here." Dana ·More said seriously.
"No need for this, she is one of us, so I stay voluntarily." Aubrey quickly took the initiative to express his position.
“In fact, I am also counting on someone to become a member of our wanted criminal team in the near future. Hannah should have mentioned it to you before, remember, Alice?
I just don’t know if you will still have the courage to go to Quantico for field agent training when this is all over.”
Jack's half-truth and half-false words made the beautiful technician look up in surprise, and the next moment her eyes were filled with tears, but this time she was more moved.
She clenched her fists fiercely and gritted her teeth and said, "Of course, if I can survive, nothing in this world should scare me anymore."
"Then one It's a promise." Seeing that his words were working, Jack pulled his female boss aside and reported in a low voice the results of his inspection.
“The design of the detonation device is extremely complex. The detonators inserted in the explosives are either real or fake and are difficult to dismantle in a short time. There are two detonation methods. In addition to the bluffing timer, there is also a connection on it.
However, there are two corresponding ways to release it. Enter the correct password on the keyboard under the timer, or release it through the remote control. Of course, the latter is just my guess and needs to be released. You have to disassemble the remote control yourself to confirm.”
Dana Moger keenly grasped the key point, "In other words, there is a suspect lurking near the Federal Building, watching every move here?"
Jack nodded, "No more than one kilometer away. , this wireless radio modified from ordinary civilian walkie-talkies The power of the radio receiver is limited, and in order to observe the entry and exit of the federal building, the suspect will not be too far away."
"We have used radio jammers before in the Emma Kane case. Is it possible this time?" Dana Moge's eyes lit up.
"Yes, but I suggest not to use it for the time being." Jack's words made the female boss stunned.
“Obviously, the purpose of both the timer and the small keyboard used to enter the password is to tell us that only by releasing Vargas can the bomb explode.
The remote control detonation is just a safety net. Once the radio signal is completely blocked, the other party can detect the abnormality by just looking at the mobile phone. At that time, it will be difficult to find them and use the remote control to cancel the countdown. "
Dana Moger lowered his head and thought for a moment, then raised his head again as if he had made some determination, "I leave this to you. Hannah and some field agents who have not entered the building are arriving one after another. Zhu Barr and everyone in the operations center will cooperate with them to identify the suspect. "
The clicking sound of the female boss's high heels left the lobby on the first floor at an unprecedented frequency. Jack turned back to Alice. Aubrey actually told her about the FBI at this time. Joke.
"A teacher met his former student Brian on the street, who is now an FBI agent. He complained that his students were so ridiculous now, and asked them "Uncle Tom's" during class. Who wrote "The Little House"? Everyone answered, "I didn't write it."
Brian said confidently, 'This is a small problem, just leave it to me.' A week later, the FBI excitedly went to the teacher and said, 'The matter is solved, that boy Henry is here. Yes, he did it! ’”
Alice was actually moved to tears by this corny joke transplanted from the Soviet Union. It was obvious that the two of them were trying hard to make the other relax and prevent her from doing irrational behavior, such as trying to go directly Pull off the dense wires and detonators on C4 on the chest.
The other one is also trying to cooperate, trying to divert his attention, trying his best to ignore the explosives on his body and Clay's action of checking the collar.
"How is the situation?" Jack asked directly in front of Alice. At this time, avoiding the person's questioning will only make her more frightened and make Aubrey's previous efforts in vain. Of course, at the same time, Out of confidence in Clay's technology. Clay subconsciously looked at Alice, then at Jack, and immediately understood what he was thinking, and told the truth directly.
"Each pack of C4 contains four electro-sensitive detonators, some real and some fake. At least two of them are fake detonators that are internally connected by thin copper wires to maintain the path. Once you try to remove it, Except it will explode immediately
I calculated the time and found that it would take at least 40 minutes to remove all these detonators. The other party was a master. "
Jack glanced at the timer. Now they have 25 minutes left, but who knows if the time on the timer is accurate. This is not a movie. There is never a rule that the timer on a time bomb must be certain. To be accurate, that thing is just a reference.
"What about removing the collar directly? I can easily get the mechanical lock on it, but I suspect it's a trap. "Jack just made a preliminary inspection and is not too sure yet.
Clay lifted up Alice's long hair to reveal the collar connection on the back of her neck, where there is a mechanical lock into which a key can be inserted.< br>
“I checked and there is nothing wrong with the lock, but there is a section of plastic conduit exposed at the latch. Do you see it? Camouflaged with metallic paint. ”
Jack tried hard to recall the bomb disposal training he had received in Virginia Beach, and then suddenly realized, "Mercury switch?"
The so-called mercury switch uses the conductivity of mercury to install a ring of conduits in the collar, and the conduits are filled Mercury keeps the entire circuit open.
Once someone attempts to violently destroy the collar, causing mercury to leak and the circuit path status to be destroyed, it will explode.
Jack has understood Clay's idea. He found the contacts at both ends of the mercury switch and used a wire as a bridge to maintain the circuit. In this way, the entire explosive collar can be removed smoothly as long as the mechanical lock is opened. , but before that, the mercury in the entire catheter must become solid.
At this time, several FBI colleagues had already moved several boxes over. Inside were the spare equipment of the bomb disposal team upstairs. In addition to various tools, there were also two sets of explosion-proof suits that looked like space suits.
"We need dry ice or liquid nitrogen here. Uh, liquid nitrogen is safer. Get some plasticine and silica gel sheets."
Jack ordered. The freezing point of mercury is minus 39 degrees Celsius, and the silica gel sheets are used. It was placed between Alice's neck and the collar to prevent her from getting frostbite. As for the plasticine, it was of course used to fix the bridge lines.
He thought for a while and continued to add, "In addition, notify the NYPD to prepare a vehicle-mounted explosion-proof canister and park it a block away on standby."
"So, you have a way to dismantle this thing. Right?" Alice, who had been sitting stiffly, had worked in the FBI for several years. Although she couldn't fully understand these words, she could still understand the general meaning.
When she first heard that there was not enough time, her expression was on the verge of despair, but the subsequent conversation between the two rekindled her hope, and her mood seemed to be on a roller coaster.
"Of course, it's a piece of cake." Jack looked confident as he and Clay helped each other put on the explosion-proof suits.
"Do it now?" Clay asked in a low voice while Alice was not paying attention.
Jack took advantage of the action of putting on his helmet and replied in a low voice, "Wait ten minutes, let's make preparations first. Hannah is leading people outside to search for the suspect. It's best to pass the suspect's hand." The remote control device on the detonator disarms the detonator, and the risk of forced dismantling is the greatest.”
