Chapter 352 Muggle Jack
Jack didn't think there was anything noteworthy about this. People get motion sickness and airsickness. The plane definitely couldn't fly smoothly before the accident. Isn't it normal for passengers to vomit?
Unexpectedly, Red's words caught the attention of NTSB official Leo Box. He came forward to observe the carpet carefully and nodded in agreement.
"It's an interesting discovery. I also found similar vomit marks in the rear fuselage section before. I thought it was just an exception. It seems that the plane may have experienced an unusual longitudinal turbulence. I will write this speculation in the report middle."
Seeing Jack's confused look, Rhett took the initiative to explain with gestures.
"Longitudinal bumps, like riding a roller coaster, constantly up and down."
Jack waved his hands repeatedly. He was not a fool, so he certainly understood the meaning of the word.
"I mean, isn't it normal for the plane to have this kind of turbulence, or when it encounters bad conditions?"
"So, will you throw up after riding a roller coaster?" Red looked at him like he was looking at a Muggle, which was very unpleasant.
Jack shook his head and resisted the urge to deal with this kid immediately. It seemed that he had neglected to take care of him recently.
"Everyone's tolerance for vertical bumps is different, just like riding a roller coaster. Most normal people would not vomit in mid-air, otherwise" Reid continued to explain.
Jack nodded quickly to express his understanding. The picture was too beautiful, so he had better not imagine it.
"You can think of this longitudinal bump as a frequency. Only when it reaches a certain frequency can normal people have a vomiting reaction in a short period of time." Reid finally reached the key point.
"So under what circumstances would the aircraft experience longitudinal turbulence of this frequency?" Jack asked.
"It was caught in the wake of another large passenger plane, but there was no second plane nearby on the radar at the time." Lillo Box shrugged, denying this speculation.
"Or maybe the slats were opened in mid-air." Rhett offered a different opinion.
Leo Box shook his head and objected, "It is too rare for the slats to open during flight. There are multiple insurances to prevent this from happening."
"It's rare for a large passenger plane to have an air crash, isn't it?" Rhett retorted unconvinced.
"Stop, stop, please explain, what is a slat? Shouldn't it be called a flap or aileron?" Muggle Jack became more and more confused as he listened.
After all, he was also a player of "War Thunder" (an air combat game created by Mao Zi) in his previous life. He had nearly tens of thousands of aircraft shot down and shot down. Why did he suddenly not understand what these two people were talking about?
"It's different. The wing has many different airfoils. The ailerons are installed at the rear of the wing, and the flaps have both leading edge flaps and trailing edge flaps. In addition, there are leading edge slats, flight spoilers, etc. Flow panels, ground spoilers.”
Seeing that mosquito coils had appeared in Jack's eyes, Rhett simply turned over the aerial photo of the scene map in his hand, took out a pen and drew a schematic diagram of an airplane wing on the back.
"The wing composition of large passenger aircraft is relatively complex. For example, leading edge slats are usually only opened when the aircraft takes off and lands, which is used to increase the critical angle of attack of the aircraft and reduce the possibility of stalling."
"But if it suddenly opens in mid-air, it's a disaster."
Jack nodded to show that he understood, and the useless knowledge was +1 again.
"Oh, damn, trouble is coming." Leo Box stopped his discussion with Red, suddenly looked not far away, and then uttered a curse word.
I saw seven or eight news trucks driving into the scene in a row, with the logos of various TV stations printed on the cars.
"It seems I have to excuse myself. The biggest challenge in this type of investigation is to stay ahead of the media and boring conspiracy theories."
Lilo Box said goodbye to the two of them with a look of helplessness.
"Fortunately, this is a joint investigation and there are dedicated people to deal with these guys. Otherwise, I'm afraid Jiejie won't even have time to sleep at night."
Jack sighed, turned around, and Red continued to search for clues at the scene. Of course, they could only glance at many places in a flash.
Analyzing large-scale air crashes is a hard job calculated on a monthly basis, and sometimes it can even last for years. Fortunately, these are the tasks of the NTSB. What the FBI has to do is to rule out terrorist attacks as soon as possible. possible.
After suffering from 9/11, the federal government is frightened by such air crashes. Excluding conspiracy theories, at least within the FBI, such cases are taken extremely seriously.
Once certain unfavorable conclusions are drawn, the FBI will issue a warning as soon as possible and leave it to senior officials to decide whether it is necessary to ground all flights within a short period of time until the possibility of subsequent terrorist attacks is eliminated.
In addition to the smoking wreckage and mutilated corpses, there were also a lot of luggage and passenger belongings scattered around.
The two found some children's toys and even infant bottles and diapers among these things. Although the NTSB has not sent a specific passenger list, it is obvious that these innocent victims include more than A minor.
"I hope this is just a simple accident." Jack sighed. No matter how he killed the murderer, he could only comfort the family of the deceased to a certain extent, but the deceased was gone after all.
Before dark, Jack and Red left the scene. They were now rushing to the hospital to join Jie Jie and Emily who were guarding the hospital.
Hotchner and Rossi, who were at the emergency command center of the Colorado Emergency Management Agency, called and confirmed that Flight 420 should not have passed through Colorado. The crash site and the actual route deviated by 150 miles.
The air controller lost contact with the plane 13 minutes before the crash. In other words, the plane yawed almost as soon as it lost contact with the ground.
Ten minutes after the loss of contact, that is, three minutes before the plane crashed, ACARS (Communications Addressing Reporting System) was shut down without knowing whether it was automatic or manual.
The ACARS system can be regarded as an air-ground data link, used to transmit data between aircraft and ground stations.
For example, when the ACARS subsystem on the aircraft detects an abnormality in the engine, it will automatically generate a message and send it to the ground via the radio transceiver, so that ground maintenance personnel can obtain the data in real time.
Therefore, when ACARS is turned off, the ground airport has no idea what happened in the air and can only analyze the black box data afterwards.
Now Hotchner is working with a military commander from DHS (Department of Homeland Security) to interrogate the witness who reported seeing the so-called 'light band' to the police.
The trouble was that the old man named Petoskey was a typical conspiracy theorist and full of antagonism towards the uniformed military representatives, and the situation temporarily reached a stalemate.
