Can a spark cause jet fuel to explode?

A spark alone typically won't cause jet fuel to explode, as jet fuel is not highly volatile and requires specific conditions for combustion. However, if the spark occurs in an environment with a sufficient concentration of fuel vapor and an appropriate air mixture, it could ignite the fuel, leading to a fire or explosion. Factors such as temperature, pressure, and the presence of an ignition source play crucial roles in the potential for an explosive reaction.
