“Mexico?”

After listening to Jack’s analysis, May 47 quickly asked, “Inspector Li, what do you mean, when we go to the United States to perform a mission, the plane will land first in Mexico, and then we move into the United States by land?”

“Yes.” Jack nodded and said, “This is the most reliable way for me. Other methods are too difficult since they use planes to transport you. You must have a landing site, and neither the United States nor Canada can allow them to bypass customs and enter quietly, and only Mexico has this condition.”

May 47 asked in confusion, “The plane enters Mexico, what does it mean? Don’t you need to go through customs?”

Jack explained, “There are two steps to enter the airport, one is air traffic control, the other is customs, air traffic control is to control the aircraft before the plane lands, and the custom is to control the passengers and goods after the plane lands. In the world, no one can completely hide the whereabouts of the plane unless he is dead because the current density of civil airliners is too high. The flight must be arranged and dispatched by air traffic control, otherwise it is very likely to have a collision, so I speculate the plane that sent you at the beginning must be a normally registered plane and applied for a route in compliance with the regulations.”

After speaking, Jack added, “But the advantage of them choosing Mexico is that after the plane lands, they have to get to Mexico. It must be much easier than the United States and Canada to transport your soldiers out of the customs.”

May 47 nodded lightly and asked Jack, “Inspector Li, what are you going to do next? You just said that the plane can’t hide its whereabouts, so start the investigation from the plane?”
