The correct url is http://nira.chicago.il.us/ Unfortunately
nira.org|com|net were all taken when we looked for a domain name.
It is a great article, but Bob didn't write it. Bruce Levison wrote
it and the companion piece 'Ablative Blast Deflectors' that was
in the Jan/Feb 99 issue (my first issue as editor, btw). I believe
both articles also appeared in Sports rocketry about the same time.
Both Bruce and Bob write very excellent articles - I just wish they'd
do so more often. Luckily, the Leading Edge has a great talent pool
to draw from for articles.
