This note from Steve about drilling holes in the spar web - at least inboard
where structural integrity is so important - is really scary. We're all test
pilots to a certain degree, but adding such a BIG unknown to your wing spar
puts you right up there with some of the guys at Edwards AFB - except they
can eject if something breaks.

I like Don as a person and I'm sure he has a lot of experience flying these
things, but I'd sure want to see some real (not "thumb-in-the-wind") data on
stress concentrations once one puts holes in a perfectly sound spar web.

All may be perfectly OK, however, if not, you'll be the owner of some very
interesting (and totally useless) failure data - for the length of time it
takes you to get to the ground!
