Chapter 22 — Between Two Runways

The sound of drilling machines rang out from the area where the new radar antenna was located, about three hundred meters from the command room, regularly since seven o'clock in the morning, an unfamiliar sound that had become familiar to Boi Thu over the past three weeks, since the day the first construction team arrived to erect the scaffolding.

Nine months have passed since the stormy night on the Vinh Ky range. The new radar system, according to the schedule recorded in the documents approved by the investment committee, is entering the final installation phase, scheduled for trial operation in the next six weeks.

"The secondary runway is temporarily closed in the west area for the next two hours for construction," Boi Thu said into the microphone, an order she was familiar with since the construction site began operations. "All agricultural and training flights adjust schedules accordingly."

This morning's shift was uneventful: four regularly scheduled commercial trips, two training trips, and clear, cloudless weather, the kind of weather any controller would call an "easy shift." Kha Viet Bach sat in the main position next to her, no longer in the observation position of a student - three months ago, he had completed the full training program, officially received his access controller certificate, and was now on duty with her as a colleague, not a mentor.

"How different do you think the new radar will be?" Bach asked, in a short silence between two flights.

"I wasn't sure until I used it myself," Boi Thu said. "But I think the biggest difference is not the scanning speed or accuracy, but the feeling of no longer having to automatically compensate for lag in my head every time I look at the screen. That feeling, I'm so used to that I don't realize it's a burden, until I think about not needing it anymore."

Bach nodded, didn't say anything more, just returned to his work, and Boi Thu looked at him for a moment — the hesitant student she once taught in the simulation training room, had now become a steady controller, with quick reflexes, no trace of the hesitation that had caused them both to relearn the same lesson in different ways.

Fifteen minutes later, a training flight requested permission to change altitude because it encountered slight turbulence from hot air rising from the construction site area. Bach acted immediately, his voice was firm, without any hesitation, giving new orders within less than three seconds of receiving the request.

"Good," Boi Thu said, not needing to look back at the screen to know he did it right. "You no longer need me to double-check every step like before."

"I still like you to check," Bach said, smiling a little. "It's just that now there are fewer mistakes for me to fix."

"That's exactly the goal of the entire training process," Boi Thu said. "Not so that you never need anyone to check, but so that you are confident enough to know when you're right, and humble enough to still want to be checked."

Than Van Khoat stopped by the radar room in the middle of his shift, bringing two cups of tea, a new habit he has maintained for several months now. "I heard that next week the construction site will finish installing the main antenna," he said, placing his cup of tea next to Boi Thu. "I doubted you quite a bit when you first came back. Now, looking at you sitting here, teaching Bach to handle every situation so smoothly, I think I was wrong."

"You're not wrong," Boi Thu said, accepting the cup of tea. "You're just being careful when you need to be careful. I think that's why this station has remained safe all these years, not because no one ever suspected, but because there were always people who dared to voice their doubts instead of staying silent."

In the middle of the shift, the internal phone rang. Banh Nghien Thao, called to confirm the schedule for the final three-month long-term follow-up psychological evaluation, completed last week.

"The assessment results have been sent to your file," Thao said. "No further follow-up is required. You have officially closed the entire process following the incident."

"Thank you," Boi Thu said, feeling a small but certain relief, no longer the rush of emotion like the first few months, but a quiet recognition that a chapter had truly closed.

"I heard that your case, anonymously, has been included in the reporting culture training documents for the entire industry, just as investigator Khoi once proposed," Thao added. "I thought you should know, because it's part of your achievements that you deserve to be recognized for."

"Thank you for letting me know," Boi Thu said. "I still remember the question you asked me in the first session — if I could come back tomorrow, would I want to come back? At that time I answered a beat slower. Now, if you asked me that question again, I think I would answer immediately, without any hesitation."

"That's the best sign I could expect from any case I've ever followed," Thao said, her voice warmer than usual. "Wishing you safe shifts ahead, Controller Ky."

Boi Thu hung up the phone, sat quietly for a moment, just looking out the glass window, where the new radar construction site was still in operation, the steady sound of drilling machines echoed in, mingling with the sound of airplane engines rolling on the main runway.

At the end of the shift, when Dieu Van came in to receive the handover, Boi Thu stood up, stretched, feeling the usual fatigue of an eight-hour shift, no more, no less - no longer the familiar trembling that had accompanied her every time she left her duty chair in the first months back.

"Last shift before you take two weeks off, right?" Van asked, taking a seat, eyes quickly scanning the traffic monitoring board.

"That's right. This is the first time I've taken a full leave of absence since I started working here." Boi Thu smiled, a light smile, without further explanation, this was also a sign that she had learned to trust that the station still operated well even when she was not present.

"Are you going out somewhere?" Van asked, curious.

"I plan to return to Bach Lung for a few days," Boi Thu said. "Miss Van - Mr. Thuyen's wife - invited me to visit when I have free time. I think it's time."

Van nodded, didn't ask further, just put his hand on her shoulder for a moment, a gesture that had become a private language between the two of them over the past months.

"What are you going to say to Miss Van?" Van asked further, sincerely curious.

"I don't know exactly yet," Boi Thu admitted. "Perhaps it's as simple as telling you how things have been since I last came in—first shift back, storm over Vinh Ky, new radar nearing completion. I think you deserve to know that the story doesn't stop with the pain, but continues, in a better direction."

"You've changed a lot since the day I first met you seven years ago," Van said, smiling. "Not the kind of loud change. The kind of change that is silent, but certain."

"I hope it's a good change," Boi Thu said.

"Absolutely," Van replied, without hesitation.

Boi Thu walked out of the radar room, along the familiar hallway, past Chuong Ba Vong's office - the door was open, he was on the phone, gently waving to her through the door frame - then out to the parking lot, where the sound of drilling machines from the new radar site still echoed in the distance, a sound of change slowly taking shape, not loudly announced, just quietly progressing day by day.

Along the hallway, she passed by the shift board posted on the wall, where her name now appeared regularly again as before, without any handwritten dashes, and next to it, the name Kha Viet Bach also appeared, no longer accompanied by the word "student" like before, but standing on par with the other veteran names in the station, a small detail but made her stop and look for a second before continuing to walk.

Before getting in the car, she stood for a moment, looking towards the command post, where just ten minutes ago she was sitting in her familiar position, the headset was now put back in the right place on the console, next to the position where Van was continuing her shift, ready for the next person to put it on, continuing a rhythm that never stops, shift after shift, day after day, between the two runways of a small airport located quietly between two mountain ranges.

She opened the car door, sat in the driver's seat, but did not immediately start the engine. Through the windshield, she looked at the new radar construction site scaffolding silhouetted against the morning sky, the workers moving steadily between the steel bars, and further away, another plane was taking off, its fuselage reflecting the morning sunlight, gently leaving the runway, carrying on a normal journey with none of the passengers on board knowing what had been going on in the small room below for the past nine months.

That's what she realized she loved most about this job — where she relearned, in the slowest and most difficult way possible, that silence is never a safer option than a voice, and that one can fall and get back up, not by forgetting what happened, but by carrying it along, more gently, as a part of oneself.
