Might have, I don't read that magazine all that often... just
occasionally in line at the supermarket while getting yet more cat
litter.

I'm actually waiting patiently for ceramics and composites to become
"regular".  Most of these materials don't retain or reflect heat as well
as aluminum/iron/steel, and certainly weight a lot less.

Less heat retention = less detonation = more boost :)
