A Delta Airlines ‘flight 89’ dumped fuel over a Los Angeles schools as it attempted an emergency landing at LAX on 14 January 2020.
It is claimed around 60 people including children was exposed to the fuel dump and was treated for breathing problems and skin irritation, fortunately no one had to go to the hospital.
It is very unusual for a aircraft to be dumping fuel in this way, normally the aircraft would do a go around and dump fuel over sea or on land where no houses or schools are,
The Boeing 777 took off from Los Angeles Airport towards China with all going well when suddenly something went wrong and the stall warning indicated so they had to quickly land, according to what we have read ATC (AIr Traffic Control) asked the pilot if they wanted to dump fuel over the Pacific Ocean to which the captain declined and continued it was then the fuel was dumped which one captain said would have been around 15-20,000 gallons of jet fuel.
When an aircraft dumps fuel it forms a mist which by the time it reaches ground level it will have no effect, however as in this case it is dumped on populated areas then it is easily breathed in and will cause irritation to exposed skin.
The FAA are currently investigating the incident.
