In my 30-year journalism career, I’ve covered more major news than I can recall.

In most cases, I’ve experienced an adrenaline rush as I set about to do my job, which I consider as much a calling as a profession.

A few times, though, a particular story has felt absolutely overwhelming, like it dwarfed me and my ability to cover it adequately.

The first time came on April 19, 1995, when my colleagues at The Oklahoman and I suddenly found ourselves reporting on what was then the deadliest terrorist attack on U.S. soil — the bombing of the Alfred P. Murrah Federal Building in Oklahoma City. In all, 168 of our friends and neighbors died that day.

The second time came six years later on Sept. 11, 2001, when terrorist-piloted planes crashed into the World Trade Center, the Pentagon and a field near Shanksville, Pa. The death toll that day: 2,977.

Now, the world finds itself grappling with an invisible killer: COVID-19. As I type this, the global coronavirus pandemic has resulted in more than 10,000 deaths. The number of infections approaches 250,000.

In an interview with Poynter.org, NBC’s Lester Holt — whom I respect — said: “I always thought 9/11 would be the biggest story I would ever cover. But this is the biggest story we have ever seen.”

Wow. That’s an amazing statement from a journalist of Holt’s status.

Is he right? Is this “the biggest story we have ever seen?” I’d humbly suggest that we don’t know yet, as massive and, yes, as absolutely overwhelming as COVID-19 seems at this point.

I asked a few respected colleagues for their insights on that question as well as details on how their news organizations are covering this major, major news.
