A plane was forced to make an emergency landing after a passenger struck a match to cover up the smell of her breaking wind.
The American Airlines flight from Washington to Dallas made an unscheduled stop in Nashville on Tuesday after travellers smelled struck matches.
All 99 passengers and five crew members were led off the aircraft, along with their luggage, while sniffer dogs checked for explosives.
After the police dogs found burned-out matches, the woman passenger admitted to FBI agents she had lit the flames.
The Texan, who lives near Dallas, said she struck the matches in a bid to try and conceal the odour.
Lynne Lowrance, a spokeswoman for the Nashville International Airport Authority, said the woman, who suffers from a medical condition, had not been allowed back on the flight.
Although the woman was released without charge, she added: "American has banned her for a long time."
The spokeswoman said that while passengers could carry up to four books of paper safety matches on to an aircraft, it was illegal to strike one on board.
It is believed the effects of passing wind on a plane are made more drastic by cabin pressurisation.
