yep, the liquid boils of fast, but the GOX once having saturated the porous material stays in the material for surprising long time and therefore makes it a flammable or even an explosive material.

That's why I always force my students to wear non porous clothes/aprons etc when handling LOX (Along with other stuff like insulated non porous gloves, face shields, non synthetic clothes underneath the apron to avoid electrostatic discharges and in the event of fire the molten plastics does not burn itself through the skin etc)

The liquid rapidly boils off leaving only gas, and frozen organic matter isn't very porous so minimal fire risk once the liquid is gone
plus this was war.
Yes, I love those old models, pretty accurate reproductions. The US copied the design in the Redstone
and Jupiter C launchers.

    remembering my Revell model set :-)

    that was an "inverted aerospike" / tip upside concave cone
