Why can't cryogenic oxygen and cryogenic kerosene be "stored" together?

As Organic Marble hints, there is about 140 degrees Celsius between kerosene's freezing point and oxygen's boiling point; there's no temperature at which both are liquid. Even if the propellants were ...

Why can't cryogenic oxygen and cryogenic kerosene be "stored" together?

to put it in 3 words "it will explode." you see fuel burns with oxidiser and mixing the two in the same storage will well let me make it in steps: you ignite the engine... the flame flows into the ...
