Why do jets leave a white trail behind them.

If jet fuel is full of water, how do you get it to burn? When I took
chemistry, hydrocarbon fuels contained .... drum roll please ... carbon
and hydrogen. No water of any level of significance.


For it to burn, there must be oxygen present, right? And hydrogen and
oxygen give you what?

Hint: the oxygen doesn't come from the fuel. Hence the fuel isn't full
of oxygen. The fuel is full of hydrogen. That is only half of what you
need to make water.
