Klenow, I gave you the only possible
answer. This 'DynaSoar' guy is 'grinding
an axe', and has Falsely commented on
the discussions I posted in reply to your

And, BTW, if you are quoted Correctly,
below, then you've misspoken with re-
spect to what the article you've cited says.

It describes an =increase= in the kindling
threshold, not a decrease.

Cheers, ken [k. p. collins]
