It definitely is a use once ;-]  They shoot the charges 4-12km and each
shot costs
at least $75+. The idea is to allow an air burst so the full concussive
force hits the
snow. Its more effective than the standard fusing which simply hits and
buries into
the snow and explodes. The snow actually dampens the force enough to be
noticeable.

This would be a secondary fusing system so that if it was set right it
would go off just
above the snow but if it failed it will have the standard fusing. If it
works right they can
reduce the size of the charges or have to make fewer shots and more than
pay for the
pic.
