Four teachers are suing Delta Air Lines after one of its aircraft dumped fuel over schools as it made an emergency landing.
The flight was forced to return to Los Angeles International Airport because of engine problems.
Delta confirmed the plane had dumped the fuel to reduce its landing weight. Nearly 60 people were treated at six local schools, many of them children.
The four teachers are now seeking unspecified damages over the incident.
“The plaintiffs could feel the fuel on their clothes, their flesh, their eyes and their skin,” a lawyer for the teachers said, adding that the fuel “penetrated their mouths and noses as well, producing a lasting and severe irritation”.
