Several commercial airline pilots reported seeing a small bunch of helium balloons near Dallas/Fort Worth International Airport Thursday afternoon, the Federal Aviation Administration says.
The balloons, which were seen at an altitude of about 3,000 feet, were also spotted by controllers in a tower on the west side of the airport, the FAA said.
At least one pilot may have had to change course to avoid the balloons.
Initial reports to the FAA said a camera may have been suspended beneath the balloons.
At last check, the balloons had drifted northwest, away from the airport.
Departures at D/FW Airport, which are currently to the south, are continuing and not affected, the FAA said.
