Tom,
glad to please and to bring back fond memories. Personally though the thought of throwing yourself out of a perfectly good aircraft on a bedsheet scares the sh*t out of me. each to thier own though. <img src="images/graemlins/cool.gif" alt="" />
On a lighter note I liberated one of the natick stoves in Kosovo and use it all the time now, working and hillwalking. All I did was flare the narrow(top)out a bit and it sits on a folded piece of heavy tin foil. For its simplicity its great. Just a shame we (british) didnt think of it first. Oops nothing new there then.
