Frontier Airlines officials believe a suspicious substance found aboard a flight from Phoenix to Milwaukee that prompted a response from the Milwaukee Fire Department's Hazardous Materials Unit is actually baby powder.
The white powdery substance was found on a diaper changing counter in one of the aircraft's lavatories by a flight attendant making her final check before landing on Friday afternoon, Frontier spokesman Peter Kowalchuk said.
The powder appeared to be in a dotted pattern, there was as diaper in a waste bin and there were two infants onboard the flight, Kowalchuk said. "We contacted the Transportation Safety Administration out of an abundance of caution," Kowalchuk said.
"We're confident the substance was baby powder and that at no time was anybody in danger," he said. During the incident the airport terminal was not evacuated, the runways remained open and other arriving and department flights were not affected, he said.
