Word started to spread to old friends that there was a Jeremy Glick on the fateful flight, and nobody had to hear it twice to believe it was their Jeremy Glick. He was an all-state wrestler for Saddle River Day School in Northern, N.J., a judo champion. Josh Denbeaux, a lawyer and high school buddy of Jeremy's oldest brother, Jonah, insisted: "Those attackers are pretty f----, sorry, because they ran into the toughest son of a bitch I've ever known ... He wasn't just going to be fighting them, he was going to be the leader of it."
...
"Immediately, I knew he was one of the guys who took them down," said Joe Augineillo, who coached Glick's high school soccer team. "I guarantee it. He was a tough, hard-nosed kid. He was my captain, the protector on my team, and if you gave him a bloody nose, and knocked his teeth out, he'd still be coming after you again. He wasn't the most talented kid on the team, but Lord, you never wanted to be in that kid's way."
