The Fourth Annual New Orleans 9/11 Memorial Stair Climb on Saturday, September 21st pays tribute to the 343 firefighters, 60 law enforcement officers, and 8 emergency medical technicians who made the ultimate sacrifice with their lives on September 11, 2001. Newell, who intentionally began his career in radio on September 11, 2017, was honored to have three very special guests in studio today to talk about the event, and share some personal stories about where their lives took them on that terrible day 18 years ago.You've heard stories from heroes on "The Pile," but you may not have heard anything from heroes underneath it. New York firefighters Tim Duffy and Joe Torrillo were both buried alive that day as they ran into the fight to save civilian lives. Joe told the story of being caught underneath the South Tower when it came down."I started running but I didn't make it - a piece of steel hit me in the back of my head and split it wide open. Huge slabs of concrete hit my body, all my ribs were broken, my left arm was snapped in half, my neck and spine were crushed, I was bleeding internally and I was suffocating under tons of steel and concrete, buried with all these other people... they found me later that day and I woke up in an operating room in New Jersey, but I was wearing another firefighters' coat. We write our names on the inside, mine said Tommy McNamara. For three days they didn't know where I was."Tim is the subject of one of the days' most iconic photos, driving his Harley through the rubble in full FDNY gear. He recounted the sensations he experienced of having to crawl through the rubble and dust."It felt like I was stuck inside a bag of cement... it was clumping up in my mouth and I was swallowing clumps but on the way down it was wicking the moisture out of my eyes, my nose, my mouth, my ears. I was starting to suffocate. I was lucky enough to get into the Brooks Brothers at Church and Liberty and did a preliminary search of the first floor, did a preliminary search of the second floor and came down and ran into Billy Quick, who passed away three or four years ago of cancer... I heard this sucking sound and knew somebody was in there with a mask. I ran over to him and took a couple of hits, took a couple of packs of handkerchiefs of the shelf at put one around my face. It helped a little bit but wasn't that great.""We now know that so many of the brothers and sisters that were with you with that day are still losing their lives today," Newell said, referring to the suite of 9/11 related illnesses and cancers that many of the days' first responders have been afflicted with. "I've followed many of them over the years, and their struggles. I'm sure many of them are your friends. It kind of struck me that we had this conversation in Congress about the trials and tribulations folks and their families are going through today. Tell us a little bit about that struggle.""Between police, fire, EMS, ironworkers, I think every day and a half we're losing somebody," Tim replied. "Just a couple of months ago we lost three guys on a Wednesday, three firemen. You do the best you can and hope your clock gets dragged out. Because it's coming. It's only a matter of time.""Joe, from the day of to the years after, when you look back - what are the changes that really strike you the most?" Newell asked.
