Visit sleepnumber.com for a store near you. Southwest airlines plane. About 20 minutes into the flight -- We transported one patient in critical condition. I saw one passenger was brought to the hospital like ok but the whole plane didn't crash. She can't be injured that bad. She's just in a hospital but I can get out there and I can hold her hand and love on her. Reporter: Michael Riordan, married for 21 years to Jennifer, sat down with me on one of those heart wrenching days just after her death. And then two minutes later, I got a phone call from the doctor who said we're sorry we tried everything we could. She couldn't make it. I immediately thought of the kids and how you tell your kids and their mom's gone. Reporter: He gathered his 10-year-old son and 12-year-old daughter at the most comforting place he knew, the church where he and Jennifer had celebrated their kids' baptisms and first communions. I just held their little hands. We took a knee and I said mommy's not going to come home guys and I don't know what that means for the rest of our life yet or tomorrow. But what we're going to live out the rest of our life with mommy in our hearts and in the way that she wanted us to be. Reporter: Starting with this memorial service. Why is everybody so quiet? It's a celebration. Reporter: You spoke at her memorial and said that you didn't want people to be quiet because it was a celebration of life. You already said it. Say it anyway. She's an amazing mom. It was the only time in the last week that I felt at peace. The love in this room, I just want to keep that going for a long time! I felt like she was just looking all over us, with her check box, like "Yes that's what I would've wanted, check! That's what I would have wanted, check!" Jen would be so proud that I'm up here because she always pushed me to be better and stronger and brighter. There's not a conversation I had with her or a text that I exchanged that didn't end with "I love you!" Reporter: Kind, loving, caring and sharing. Those are her words? Those are the words she lived by. That she spoke. There's no better way to explain Jennifer Riordan than kind, loving, caring. She was so close to heaven that the angels recognized her and plucked her from the sky. Jennifer knew this world was a good place. I give thanks today and always, for the life and the love of Jennifer Riordan. I love you! It was just the best hour, hour and a half that I'll have probably for the rest of my life now. Reporter: He said he would eventually welcome a chance to speak with the pilots, but not yet. We wanted to be respectful and let them have some time to mourn without us being public. So we haven't gotten to speak to them, but we do send them our condolences. Reporter: Mike says it's too soon for him to concentrate on the investigation into what happened. But not for others. Reporter: As you look back on what happened, do you have thoughts about the investigation, what they've found, what they haven't found, are you following -- are you tracking that? I've been tracking it, yeah. I have a lot of questions. I think it's incredibly important that they, you know, figure out what caused it. And just ways that they could, they could work to, um, avoid this situation you know, kind of moving forward. The aircraft began a rapid uncommanded left roll. Reporter: NTSB investigators have determined what went wrong. A broken fan blade. The fan blade, it separated in two places. There are 24 fan blades on that engine used to suck in massive amounts of air to propel the plane forward. Cracks, invisible to the naked eye had formed in two places on one of those blades. And when it broke, debris somehow blew apart the protective housing called the cowling. And a piece of that cowling crashed into the window. These blades are made of titanium. They are really strong. It's a really good engine and those fan blades were supposed to last for 60 thousand flights. Reporter: Southwest and the engine manufacturer expressed condolences to all affected and said they're working together to quickly inspect all of these engines in the sw fleet. The bigger picture is these engines have been flying for 20 years on 737s. Generally aviation is safer than it has ever been. Reporter: As a condition of our interview, we agreed not to ask tammie Jo and Darren about the NTSB investigation while it's still pending. But they did say, they have no qualms about flying 737s. Given what you've been through, do you feel safe in that airplane? Oh, yeah. Absolutely. Reporter: Absolutely? Absolutely. Reporter: No, you get in it
