Just an additional comment.  It is fairly easy to add a canopy open
warning system.  I added a micro switch to the latch and get a
annunciator light if the canopy is open.  In addition, I added an
aural (and more pronounced visual warning) if the canopy is unlatched
and I have attained 30 kts airspeed.  Just one way of trying to
mitigate the problem.  Be happy to share schematics if any one is
interested.
