Rick Mofina - Free Fall

But there it was.

The records didn’t lie.

Somehow that system had been turned off.

Clear River, North Dakota

Veyda was wearing a diaper and a T-shirt, and sucking on her bottle as she toddled into his study. He was working at his computer keyboard and she pressed against his knee, raising a tiny arm, forcing him to hoist her gently to his lap. She snuggled into his chest, falling asleep with her bottle as he worked with one hand while holding her with the other.

Elizabeth had captured the moment on video.

There were a few other videos and photos from their trips to Kitty Hawk and Cape Canaveral but he was often missing from ones taken at Christmas, birthdays and school events.

Looking at them now, on his computer in the gloom of his rented house, Robert Cole swallowed his pain with whiskey, letting the warmth of the alcohol flow through him. No matter how he steeled himself, no matter how much he drank, it tore him apart to look back at what he’d lost.

For not only was Elizabeth gone-he’d lost Veyda, too.

She’d been a brilliant child with an intuitive, analytical mind, an exceptional little girl. In her adolescent years, she’d read her mother’s medical textbooks, his engineering books, then their philosophy books. Plato, Nietzsche, Lao Tzu and Descartes had been her favorites. She’d forever been questioning them on subjects and concepts.

Have you ever seen a person’s soul, Mom?

What is eternal consciousness?

How do jets fly, Dad?

Veyda had loved looking over their shoulders whenever they’d worked at home, absorbing whatever she could.

But those moments had been rare for him because he’d always been at the plant, never around to do normal dad things, like taking Veyda to a museum, or going with her and Elizabeth on a hike, or helping Veyda with the science projects she’d worked so hard on. His job had always come first and before he’d realized it, the years had slipped by and Veyda had left home for college.

Their time together had been all but gone.

As Veyda accumulated one academic achievement after another, he and Elizabeth had seen less of her, which had made the few visits they’d had more meaningful-until the day of the accident.

He drank more whiskey.

Veyda had suffered a serious head injury in the crash. For months after the tragedy she’d undergone treatment and therapy before returning to MIT, determined to get her PhD as her way of honoring her mother’s memory, but in that time she’d grown distant and cold toward him. When he’d flown to Boston to spend time with her, she’d missed a dinner date with him, and had been late meeting him at his hotel. She’d behaved as if she’d resented his presence. It was as if she’d become a different person. Then, after he’d returned to California, she’d sent him an email.

I will never forgive you for what you’ve done. You loved your work more than us. In killing my mother you killed part of me. I no longer want you in my life. I never want to see you again. You are not my father and I am not your daughter. You’re a sad, ordinary man who contributes nothing to this world and I hope you die knowing that.

Her words had pierced him.

Veyda couldn’t have meant what she’d said, he’d thought, blaming it on her injury. In the days and weeks after her email, he’d tried to reach her through the school, her doctors, her therapists and, thinking she might harm herself, even police. But it had been futile. Veyda was an adult and not a threat to herself or others.

I’m afraid this is a private matter, sir, and not one for police, the officer had told him.

All of Cole’s efforts to contact her, find her, speak to her and reconcile their relationship had been in vain. They’d become estranged and she’d vanished from his life, living on her trust fund and a portion of the insurance money they’d received from the crash. Cole had withdrawn into himself. Unable to function professionally, he’d lost his job, sold their house in Burbank and moved here to North Dakota where every day, haunted by her accusations, he tried to drown his guilt with alcohol.

But he failed because what Veyda had said was true.

The evidence stared back at him from the photos he’d saved. There were more pictures of him at work than with his family. At the time of the tragedy, he’d been one of Richlon-Titan’s top quality-assurance engineers overseeing the fly-by-wire system. He’d been a highly regarded expert. He’d been asked to work with the US Air Force and national security organizations on system applications for classified projects, and he had often been called upon to provide technical help to the NTSB on crash investigations. Over the years, he’d developed professional friendships with NTSB and FAA people who’d respected his work.

He took another drink.

There was no denying it-he loved aviation and he’d loved his job. He’d enjoyed going to the RT plant each day in Burbank. Entering the massive hangar where they’d built planes, seeing the sections of fuselage, the scaffolding, the assembly jigs and hearing the rat-a-tat-tat of the riveting guns-he’d loved it all.

Moreover, he’d lived for the challenge of helping design, install and maintain RT’s digital fly-by-wire system, an extraordinarily complex control system that enabled the aircraft to be controlled by electronic signals. The basic principle meant that pilot-initiated flight controls were converted to electronic signals that were then processed by flight control computers.

The system was programmed with flight control laws that provided hazardous flight envelope protection for such things as speed, bank, angle of attack and pitch attitude. The safety features essentially assured that the inputs made by the crew were within the limits of the plane’s capability.

However, if the crew was suddenly confronted with an unusual emergency, RT’s system provided for the safety features to be manually disabled, allowing the crew to manually direct the aircraft to perform beyond programmed safety limits.

Safe operation of RT’s system was paramount. It was backed up five different ways to guard against problems such as a system failure, or the malfunction of any of the onboard computers, or loss of power.

Then there was the question of security.

Ah, yes, security .

He took another drink.

Was the fly-by-wire flight-management system vulnerable to interference by satellite transmissions or solar storms? Cole’s team had ensured that it was protected against such occurrences.

Perhaps the most contentious concern had been the one about the system’s vulnerability to a cyber attack. Was it possible for someone to seize control of the aircraft remotely? Again, based on several overarching facts, Cole’s team had been confident the answer was no. Ultimately, the flight-management system and the autopilot were controlled by the crew. The avionics systems had been designed and built with extremely high levels of security.

From time to time, reports would emerge indicating that the computer systems used in commercial jetliners today could be hacked. But such claims were always baseless.

Then an assertion surfaced at a global IT security conference in Manila that had prompted Cole’s team to reevaluate the security of the RT system. A former pilot and computer security consultant had told the conference that he’d purchased software online that he’d adapted to infiltrate the Aircraft Communications Addressing and Reporting System and the Automatic Dependent Surveillance-Broadcast System. These systems transmitted short messages between aircraft, satellites and ground stations. The consultant had said that by infiltrating the two systems, he had the capability to land or crash any plane in flight. He’d used a flight simulator and given an audiovisual presentation to demonstrate his findings.
