A female passenger became unruly after smoking in the restroom and made A Hawaii-bound Delta Air Lines Inc. jet divert to San Francisco .
The witness, Elizabeth Oglesby, told The Associated Press that the woman hit a pilot in the chest after he left the cockpit to check on her.
"She appeared to be out of her mind. Upset. Belligerent," Oglesby said. "He threatened to handcuff her if she didn't calm down. At that point she hit him in the chest."
Officials with the U.S. Transportation Security Administration and Federal Aviation Administration did not immediately release the name of the passenger, and it was not clear if she would face criminal charges. It is a federal crime to smoke on a commercial flight.
Delta Flight 511 originated in Cincinnati and was supposed to fly nonstop to Honolulu.
The woman was given oxygen and taken to a hospital.
Delta spokeswoman Chris Kelly said the plane resumed its flight about an hour later.
