An airliner grounded at St. Petersburg-Clearwater International Airport while authorities investigated a powdery substance inside the bathroom has been cleared to take off after it was determined the substance does not pose a threat.
Firefighters were called to the airport Tuesday afternoon after the pilot of an Allegiant Air plane noticed the powder, said airport spokeswoman Michele Routh.
"The captain went to use the front lavatory and noticed a white powdery substance, then called the response team," Routh said.
All of the plane's passengers had already disembarked when the dust was found.
A hazardous materials team determined the substance was residue from a new roll of toilet paper.
"It was literally paper dust," Routh said.
Flight 802 from Toledo, Ohio, landed at the airport around 12:30 p.m. and was scheduled to fly out to Plattsburgh, N.Y., at 3:10 p.m.
The plane was delayed, but was cleared for takeoff shortly before 5 p.m., Routh said.
