ok there might be sulfor in the fuel but what is the concequence of it passing through a jet engine running at 2500 degrees c?

the melting point of titanium is 1688 c the exsaust gas of a jet at full pelt is aparently 2500 c you are saying sulphor is impervious to this ?

Molten sulfur assumes a dark red color above 200 °C.
The burning of coal and/or petroleum by industry and power plants generates sulfur dioxide (SO2)
so its abundant without the need for planes to help out
