The father of the American Airlines co-pilot who died in a midair collision near Reagan National Airport in January told FOX Business Thursday a “culture of complacency” allowed the disaster to happen. 

Tim Lilley spoke about his son, First Officer Sam Lilley, ahead of a Senate hearing on the Jan. 29 collision involving an Army helicopter. National Transportation Safety Board Chair Jennifer Homendy told lawmakers the families and friends of the 67 victims “are here today,” and “I can only imagine what they’re going through.” 

“My son was an outstanding young man whose career and his life was just taking off, and we were not ready to lose him, and we never would be. And there’s 66 other families that are going through this same thing. This accident was so preventable,” Lilley told FOX Business.

Homendy opened her testimony Thursday by saying “it’s important that we remember today that those who died at DCA and in other accidents we investigate aren’t numbers. … These are mothers, fathers, sons, daughters, wives, husbands, cousins, best friends who won’t be there with their loved ones for Easter egg hunts, Passover Seders, the end of Ramadan, Mother’s Day, Father’s Day, graduation, all of life’s celebrations.

“Their families and friends, whether in person or online, are here today. I can only imagine what they’re going through, and I want to take a moment to again express our deepest sympathies to each of them,” she said. “Please know that we keep you in our hearts as we diligently work to determine how this tragedy happened. So, no one, no one experiences the deeply significant loss you must feel today.” 

Dailey Crafton, the brother of victim Casey Crafton, told FOX Business, “I think for myself, and I think most of the families, we’re looking for accountability for what happened from whatever agency needs to have accountability.

“We’re devastated. It’s a big gaping hole in our lives, and it comes in waves,” he added. “Some days are all right. Some days you can, like, you barely don’t even want to get out of bed, and you know you can’t stop thinking about it and feeling just anxious and stressed out and everything. So, it’s a roller coaster.”

Maxim Naumov, a figure skater whose parents, former Olympians Evgenia Shishkova and Vadim Naumov, died in the midair collision, told NBC’s “Today” show Thursday the last message he heard from his mother was to “let me know that they’re switching flights and that if I could pick them up.”
