American Alek Skarlatos' 1st Thought During Paris-Bound Train Was 'Just Trying Not to Die'

"I immediately recognized what was happening," Alek Skarlatos said.

"Then we just acted, and I didn’t have another conscious thought for the next two minutes.”

Skarlatos described his initial decision to jump in and help as a "gut reaction,” noting that his military training didn't kick in until later.

"We were just acting on adrenaline and doing what we had to do to survive," he said.

"Once we were able to think again, that was kind of when training kicked in, but before that, we were just trying not to die.”

After the train was stopped and the gunman was in custody, he said the magnitude of the event still hadn't hit him.

"I thought they would just question us and then put us on the next train to Paris," Skarlatos said. "I didn’t think it was going to be this big at all."

And when Skarlatos finally returned to the United States this week, he was shocked to see law enforcement officers at the airport lining up to shake his hand.

"I was so grateful to everybody that showed up for that. That was just amazing," he said. "That many law enforcement officers showing up ... it meant a lot to me."

"He’s still stuck in Ramstein, but he’s doing great," Skarlatos said today of Stone. "He's in high spirits. He just couldn’t be here today, unfortunately."

Skarlatos doesn't know what's next for him, but said, "I’m probably going to go back to Germany and hang out with Spencer."
