Subject: Burning Jet fuel to cool Beer?

A friend recently told me he and his Army buddies used to bury hot beer (during 
the Vietnam war) a few inches underground and then sperad jet fuel over the 
area and ignite it.
He claimed that after a brief period, the jet fuel extingushed itself (probably 
all fuel being consumed) and when the beer was immediately excavated, it was 
remarkably cooler.
I understand heat transfer, vaporization heat exchange etc.
It sounds almost like it could actually work.
Does it? If so, what could be the approximate temperature drop?
Thanks, I love this site!
