Ed,

How well does the position of the break line up with your exhaust port?
Are
there any tiny chips near the break that look like they may have been
around
a while?

I'm thinking of the possibility of a piece of debris chipping the seal in
the vicinity of where it flexes as it crosses over the exhaust hole.
Stress
riser, being the unpredicable ^%&# they are, will always give out just as
you cross the limit of not being able to glide home.


A good point, Ernest, I'll have to go back out and check the pieces in
better light or better yet bring them in the house where i have a couple of
magnifying glasses.

Ed
