Chapter 19 — Between Two Runways

"Hai Au is not private, wind gusts are twenty-seven knots in the approach area, direction changes continuously, confirm the possibility of landing immediately or need more time to evaluate?"

The helicopter pilot's voice responded after a few seconds of consideration, some tension evident despite trying to maintain professionalism. "We can try, Tra Son, but please give absolute priority, do not want to prolong the time in these windy conditions."

Boi Thu looked at the screen, where the helicopter's light dot was closest to the runway, less affected by the remaining traffic. Helicopters, with their greater maneuverability than fixed-wing aircraft, often tolerate wind gusts better under the control of an experienced pilot, but "better" is not the same as "absolutely safe."

"Hai Au is not private, has priority approval for immediate landing, secondary runway, current wind gusting to thirty-five, high humidity, pay attention to the phenomenon of crosswinds in the last thirty seconds of approach."

"Okay, Hai Au is not interested, approach the secondary runway."

She watched the dot of light move slowly and steadily, her eyes never leaving the screen even though her ears were still listening simultaneously to the five other communication streams that Khoat and Van were processing in parallel.

"Touched the ground safely, Hai Au is not worried," the pilot's voice rang out, clearly relieved.

Ung Thuc Lam called from the ground immediately afterward, confirming that the fire team had observed the entire landing process, no abnormalities were recorded, and ambulances were ready to receive patients from the helicopter to transfer to the hospital. Boi Thu briefly thanked her and then immediately returned to the main screen, not allowing herself to stop for too long on any completed goal.

One goal has been resolved. Five left.

"Victor Tango zero sixty nine, current fuel status?" Boi Thu asked the regular flight schedule which was holding altitude and waiting.

"There's about forty minutes left to spare, Victor Tango isn't sixty-nine."

"Receive, continue to maintain altitude, I will enter the approach in eight minutes, after the two diversions from the south have landed."

This was the hardest part of the puzzle: the two flights from the south had more limited fuel and needed priority, but the current gusts were near the safe limit for the type of plane they were flying, and the storm continued to get closer by the minute, which could push the gusts past the threshold at any time.

Khoat, who was handling communications with those two flights, turned to Boi Thu, his voice urgent but not panicked. "The first flight reported feeling strong turbulence at an altitude of three thousand feet. Please allow permission to lower to avoid it."

"Can't go any lower right now, there's still Victor Tango not sixty-nine at twenty-eight hundred below in the waiting area," Boi Thu said, doing a quick calculation in his head. "Have them turn ten degrees left, avoiding the core of the turbulence zone while maintaining altitude. I will take Victor Tango no sixty-nine and leave the holding area immediately to clear space."

"Clear." Change orders immediately.

Boi Thu turned to call Victor Tango no sixty-nine, changing her plan in a split second, a decision that required her to simultaneously visualize the positions of all six targets in three-dimensional space, calculating how to move them like pieces on an ever-changing chessboard.

The next fifteen minutes passed at an unprecedented pace, each decision following another, each command given based on instantaneous calculations of distance, altitude, speed, wind direction, all intertwined like a complex music whose full melody could only be heard by the operator.

Two diversions from the south landed safely, followed by two of the three regularly scheduled flights. Only Victor Tango, zero sixty-nine, remained, on final approach, just as the wind gusts peaked.

"Victor Tango is not sixty-nine, the current wind is thirty-two gusting to forty, the direction is constantly changing," Boi Thu said, her voice tense but still absolutely clear. "Confirmed ability to continue landing."

There was a short silence from the pilot, long enough for Boi Thu to clearly feel her heart beating faster, long enough for a part of her, the part that still carried the memories of thirty seconds eight years ago, to scream and tell them to fly back immediately.

But she waited. She let the pilot, who had all the data about the capabilities of the plane she was flying, make their own assessment first, just as the procedure required, just as she had learned from the mistake eight years ago: not making decisions for others when they had enough information and authority to decide for themselves, only providing them with the most complete and accurate information possible.

"Winds exceed our recommended limits," the pilot replied, his voice calm but decisive. "Victor Tango no sixty nine please do go-around."

"Accepted, go-around approved, fly forty-five hundred feet, keep current direction, we'll wait for the wind to calm down before trying again."

In the moment of giving that command, Boi Thu recognized an uncanny similarity to the fateful ninety seconds two months ago — same phrase, same go-around decision, but this time there was no suffocating feeling of a near-collision situation, only the familiar working rhythm of a process done properly, at the right time, without needing luck to save the situation.

The plane soared, clear of the most dangerous turbulence, and Boi Thu, though her heart was still racing, felt a deep, pervasive sense of relief — not because she had ordered a go-around, but because the pilots had made the right decision, based on their own judgment, just as a safe operating system should work: not one person imposing on another, but many layers of independent judgment working together toward a safe conclusion.

"The storm is moving faster than forecast," Van said, eyes glued to the weather update screen. "It is estimated that the peak of wind gusts will pass in about fifteen minutes, then gradually decrease."

"Then let's let Victor Tango zero sixty-nine wait fifteen minutes," Boi Thu said, already calculating the next plan in his head. "Enough fuel?"

"Just enough, there's about ten minutes left in reserve after landing," Van confirmed after a quick check.

Boi Thu nodded, conveyed the plan to the pilot, then sat back, watching the lonely dot of light left on the screen flying in a slow circle at a safe altitude, waiting for the thunderstorm below to loosen its fury.

Those fifteen minutes passed slower than any fifteen minutes Boi Thu had experienced in her career, each minute marked by rechecking wind data, updating fuel status, and an absolute concentration that did not allow her mind to wander to anything other than the plane circling above their heads.

Bach, sitting in the observation position, closely monitoring the wind gust data, updating the group every two minutes without any prompting, his voice was completely stable, no longer a trace of the tremors of the first weeks. "Wind gusts are gradually decreasing, now there are still two eight gusts three two, the direction is more stable than before."

"Continue watching," Boi Thu said, not taking his eyes off the main screen. "Report immediately if there is a sudden change in the opposite direction."

Vong, still standing in the corner of the room, looked at the clock, then at Boi Thu, said nothing, just nodded slightly, a silent gesture of encouragement that she recognized right in the midst of extreme tension. She responded with a small nod, not taking her eyes off the screen, but enough for both of them to understand each other.

By the twelfth minute, Bach reported that the wind had dropped to below twenty knots, stabilized, and was no longer gusting as strongly as before. Boi Thu checks one last time before making a decision.

"Victor Tango zero six nine, wind now one eight, gusting to two two, has been steady for three minutes straight, second approach cleared when ready."

"Receive, begin approaching, Victor Tango no sixty nine."

The whole room held its breath as they watched the last dot move slowly on the screen, moving closer to the main runway, the altitude gradually decreasing, the speed steady. Boi Thu reads the parameters out loud to the whole team, a habit she maintains throughout the shift so that everyone always knows the overall situation, no one is left behind in the rush of information.

"Two nautical miles left, altitude five hundred feet, steady speed," she said, her voice even but containing a tension that only those sitting closest to her could sense. "One nautical mile to go, two hundred feet of elevation."

Outside the window, the rain had begun to lessen in intensity, only drizzling, and a lighter gray sky was revealing behind the dark clouds that were gradually moving east, leaving behind a much clearer atmosphere than half an hour before.
