CHARLOTTE, N.C. - A Delta Air Lines (NYSE:DAL.N) flight was diverted to Charlotte, North Carolina, on Sunday after passengers mistook prayers being said by two Orthodox Jews on board as a threat, the airport manager said.

Delta Flight 458 from Atlanta to Newark, New Jersey, landed at Charlotte-Douglas International Airport, and passengers were taken off the flight while officials investigated a report of two "Middle Eastern men" creating a disturbance on board.

"Everybody is kind of on edge, and it just doesn't take much to upset a lot of people," Charlotte-Douglas International Airport operations manager Jerry Orr said.

The flight continued to Newark after officials were satisfied there was no threat, he said.

Air passengers have been jittery since the Sept. 11 attacks in which hijackers slammed jetliners into the World Trade Center in New York and the Pentagon near Washington, killing more than 5,000 people.
