FAA investigating Delta jet fuel-dumping on schoolkids in LA – By Associated Press (FOX Business) / Jan 15 2020
CUDAHY, Calif. (AP) — Federal authorities will investigate why an airliner with engine trouble dumped jet fuel over a densely populated area of Southern California while making an emergency return to the airport, dousing dozens of schoolchildren in a smelly vapor.
Delta Air Lines Flight 89 to Shanghai, with 181 passengers and crew on board, turned back to Los Angeles International Airport only minutes after taking off Tuesday.

The pilot reported a compressor stall in the right engine — damage to a jet turbine that can occur through malfunction or when a foreign object such as a bird hits an engine. The damage can reduce engine thrust or, in worst cases, lead to a fire. Planes can take off weighted down for their journey, but if they must land early because of an emergency, it can be necessary to dump fuel so that the aircraft is lighter to avoid damage.
Air traffic control asked the aircrew if they wanted to return to LAX immediately or remain over the ocean “to hold and burn fuel,” according to a recording of the radio communications.
“We’re going to go ahead,” the pilot or co-pilot responds. “We’ve got it back under control. … We’re not critical.”
“OK, so you don’t need to hold or dump fuel or anything like that?” the controller asks.
