A day after a Delta Air Lines plane dumped jet fuel over several Los Angeles schools, federal authorities said the pilots of Delta Flight 89 did not ask for approval to release the fuel as part of their emergency landing. Air crews will typically notify air traffic control of an emergency and indicate they need to dump fuel, the Federal Aviation Administration said. Air traffic controllers direct the plane to the appropriate fuel-dumping area. "A review of yesterday's air traffic control communications shows the Delta Flight 89 crew did not tell air traffic control that they needed to dump fuel," the FAA said in a statement. Delta spokesman Adrian Gee said the airline didn't have comment because the investigation is ongoing.
