FORT MYERS, Fla. - JetBlue flight 467 was the first Boston flight to arrive at Southwest Florida International Airport Tuesday.

It carried runners from the Boston Marathon and residents from Beantown who witnessed Monday's attacks.

Passengers coming off the plane said it was hard not to talk about what they had witnessed.

"It's a city still in mourning," said Daniel Palestrant, a Boston resident. "It's a tragedy. It's the oldest marathon in the world, and it's got a scar on it."

Jennifer Kahn, who recently moved to Fort Myers, arrived at RSW wearing her blue and yellow 2013 Boston Marathon jacket. The 29-year-old completed the race an hour before the twin bombs exploded.

She was about a block away at the time.

"There was a flurry of ambulances. There was a flurry of people running and crying," Kahn said. "Maybe if I hadn't had the race I wanted to have, and finished later, we would have been closer. So it was really scary."

Even though she and some others who were in Boston for the attacks narrowly escaped harm, the same can't be said for the aftermath.

Lynn McDonald, a Boston resident, was handing out water along the race route before the bombing. For her, it's hard to explain to her children what happened.

"It's awful. It's devastating," McDonald said. "I'm glad that (my kids) know we're not trying to hide it from them, but it's sad we have to live this way."
