SARASOTA (FOX 13) - Mark Grevelding is still processing what happened to him. The Sarasota aquatic instructor was in Belgium for a conference. He had just celebrated his birthday and was coming home. Friends dropped him off at the Brussels Airport and he headed to his gate.
"I had just walked away with the tickets in my hand," he recalled Monday afternoon. "There was a huge orange flash and a huge explosion."
Grevelding found himself in the middle of a terrorist attack. A wall protected him from the last, but the ceiling fell down, hitting him.
"It was just pitch black, the smoke and the dust. You didn't hear everything for just a few seconds and then the whole place came alive with people screaming and crying," he continued. "I knew it was a bomb, I knew it was terrorism. And then when the second one I thought are they going to blow up this whole airport?"
With an injured leg, he struggled to climb out of the debris.
"You just couldn't see. There was a lot of blood on the floor. A lot of debris to climb over to get out," he said.
Once he saw light, he found himself surrounded by carnage.
"You could see people helping and carrying other wounded people out...People were asking if I was in pain and compared to what I was seeing, I felt perfectly fine," he said.
Grevelding also saw the best of humanity that day. And he says nothing will ever stop him from traveling again.
"When I will always chose to think about is what people did afterward and how they helped, not what happened or why it happened. That's just hate and it can't win," he added. "It was the love of the people helping each other that you want to focus on."
