At Palm Beach International Airport, it was business as usual on Wednesday.
However, what happened aboard Southwest Flight 1380 in Philadelphia on Tuesday was on everyone's mind.
"It's everyone's worst nightmare," said Stuart Clow. "It's unsettling."
Tuesday there was an engine failure on a Southwest flight and a woman died after the window was broken by a metal fragment from the engine and she was almost sucked out of the plane.
Art Kamm, a commercial pilot, said these incidents are extremely rare. There are more than 20,000 flights a day in the United States.
He said NTSB's investigation is critical as they look into maybe why evidence of metal fatigue was not detected prior to take off.
"What exactly happened and if there will be any changes in the future," said Kamm.
