In a previous article, "Bob Kuykendall" said:
Plastic (in this case, composites) is relatively expensive stuff. Most
of it is based on petrochems, so it's going to rise in cost with the
price of oil. And if there's any carbon to it, watch out! Right now the
Airbus A380 and Boeing 787 projects are competing for all the available
carbon, so supplies for bit players like kit aircraft makers are
getting quite pricey.

Some people I know who build canoes say that it's hard to get kevlar these
days because the military is buying it all up. Kevlar makes good light
structures for canoes, you'd think it would make good LSAs as well.

I use shell scripts at ork. Some cow-orkers refuse to touch them, their
excuse is usually "I don't understand perl". Their fear of perl is such
that all things unknown are also perl. -- Andrew Dalgleish
