NEW YORK - Things are back to normal for air travel after another computer glitch hit many busy U.S. airports on Wednesday, including John F. Kennedy Airport.

This time it was a Department of Homeland Security system that went down in New York, Atlanta and Boston.

Passengers had to fill out information in long hand after the system that looks at the terror watch list was down for about 90 minutes.

So far, no word on what caused the disruption, but officials say it was not malicious.
