CNN(CNN) -- A suspicious white substance in an airplane bathroom?
It could be anthrax, could be explosive residue or -- as authorities in California learned Friday -- it could be toilet paper.
The white dust appeared in the back lavatory of Alaska Airline's Flight 508 soon after it took off Friday afternoon from Seattle, said Bobbie Eagan, a spokeswoman for the carrier. Sometime during the 1,000-mile flight, the flight's crew notified authorities about the unknown substance and asked for help.
