CHICAGO – Aviation officials say a passenger doing her nails was the source of a mysterious odor that forced a flight from Chicago to San Diego to be diverted to Denver Saturday.
Federal Aviation Administration spokesman Allen Kenitzer says the pilot noticed that his cargo included several five-liter containers of acetone, a hazardous substance.
A check found none of the containers leaking.
Authorities later determined the odor came from a passenger who was doing her nails on the flight.
It's unknown if she was using nail polish or remover — both contain acetone.
Kenitzer says nail polish is allowed aboard commercial flights.
