It was a beautiful day in New York. The towering urban forest of buildings was under a heavy rain cover the night before, but the breaking day ushered in a sky as brilliant as a robin's egg. Cloudless and crisp, it was a picture-perfect morning. I ducked out of the subway station's cover into lower Manhattan's cacophony, my mind buzzing through a checklist of appointments and tasks filling my day. As a senior account executive for Genesis Exhibits (then Skyline Manhattan), my day-to-day was a never-ending scroll of exhibit preparation. On my mind that morning was my crew, currently floating in the middle of the ocean. The team of seven was on the ship Queen Elizabeth 2 (QE2) for a first-of-its-kind floating trade show. My client, a special event company, brought more than 700 attendees onto the British passenger ship for a three-day cruise full of exhibits and social engagements. Appointments filled the days, while formal banquets occupied the nights. Limited communication with the outside world kept attendees immersed in brand messaging 24/7. The ship was sailing back to the Port of New York the next day.

My thoughts were interrupted by a high-pitched mechanical keen cutting through downtown's clamor. It was the unmistakable banshee howl of a jet engine, but it seemed to be wailing above my head instead of coming from the clouds.

I shot a glance through the spines of buildings surrounding me and glimpsed an airplane speeding through the skyline. The aircraft impaled the North Tower of the World Trade Center (WTC) in an explosion of glass and metal. Hands flew to open-jawed mouths and people watched in horror as black smoke billowed from the tower's wound. The shutter clicks of front-page moments unfolded around me. Everyone who lived through that day remembers where they were at that exact moment.

I raced to my company's office on 18th Street as soon as my brain could control my feet again and scrambled to call my wife from the office line. Cell phones in every back pocket weren't commonplace in 2001, so the moments between the crash and the call felt like an eternity. My wife of almost 10 years was newly pregnant; we had just learned the news. When she answered the call and assured me that she and the baby were safe, I almost wept. Someone wheeled an old TV into the office and the team watched history unfold. It wasn't until after the towers fell and shock gave way to rational thought that I remembered the crew and the clients on QE2.

Long-time pros are familiar with the jolt of adrenaline that accompanies a problem. “We have a job to do,” I thought. I picked up the phone.

The first call I made was to my client. In the short breath between the plane attacks and the port closures, QE2's fleet owner, Cunard, had been required to point the ship to Boston Harbor. I was relieved to learn that the client's attendees would have shelter and transportation upon arrival. It allowed me to focus on the next task: bringing my crew home.

I made another call to a phone number I had dialed many times, first when I was a music promoter in Montclair, NJ. The number belonged to Pat Alapa, owner of PCA Audio Design and Engineering. Alapa was the sound engineer and lighting director for many of the concerts I produced in my early career. Over time, we developed a trusted groove, and our natural partnership followed us through evolving job titles and companies. When the QE2 gig needed an electrician, I called him because he was someone I could count on. That same trust drove me to call him again on September 11.

We needed to help bring our team and equipment home, but everything was at a standstill. North America's airspace was grounded. Mass transit was suspended or impeded. Officials shuttered bus terminals. Ports were closed. Bridges and tunnels were limited to emergency vehicles. We needed a truck to reach our people, so we turned to our community of trusted contacts.

Alapa had a friend he worked with for years who owned a trucking company, and he was returning one of the fleet's trucks when he saw the plane hit the second tower. When I told him the QE2 crew was stranded, he called his friend, returned to the yard, and grabbed the keys. He mapped an alternative route around the labyrinth of road closures, got behind the wheel, and drove off to bring the team and equipment home. He drove from New Jersey to Boston and back again as rubble smoldered in Manhattan and ashes floated in the sky.

In the months that followed, our community — and the world — heard more stories about the people we lost and those who made it out of that unimaginable day. Mitzi Sperando, a client who had become a friend, exhibited in the Windows of the World restaurant that fateful morning. She had only been with her new company for a month, and we delivered her first exhibit to the WTC the day prior. She didn't survive the attack. Months later, I discovered that another contact, who had been on the 65th floor of Tower 2, did. When the first plane hit, she left the building despite reassurances that the second tower was unaffected. She experienced the 1993 WTC bombing, so despite advice to stay put, she grabbed her things and went home. Her company lost 65 people that morning. These are just a few of that day's thousands of painful memories we all share.

My post-9/11 all-hands-on-deck experience reminds me of the daily commitment required in the event installation and dismantle industry. Because I'm a music man, a Jackson Browne lyric comes to mind. In the song “The Load Out,” Browne pays tribute to the roadies who shoulder the heavy lifting before a single note gets played. “They're the first to come and the last to leave,” Browne sings, and that's the critical below-the-iceberg work done in the invisible industry. Having people you trust on those teams can make the difference in the face of disaster.

In the event industry, good planning is essential. You always have to have a Plan B in case the unexpected happens. You also need a trusted partner with experience and resources to make things happen. The event world is surprisingly small, and you never know when a handshake can turn into a helping hand. When Alapa and I exchanged numbers a decade ago, I didn't know how important he'd be to me. On a day no one could plan for, the people you can't do without make all the difference.
