Chris,
Would it be possible for you to share a picture of your "means of pulling down on the canopy at the top center of the roll-over."
Thanks,
Howard Swingle

When this topic came up long ago, the description sounded like the latch and striker were not engaging correctly. This could indicate a design issue, a construction issue, or even just an adjustment issue.
I do recall during construction of the latches on the 360 that the fit of the actual parts did not exactly match the layout in the plans. If one were to simply attach parts per the schematic, the latch would not fully engage the striker. This could have easily led to the canopy popping open given the right flexing of the fuselage etc. Some modification was required to match the intent of the design.
I also have a means
of pulling down on the canopy at the top center of the roll-over.

Paul,
I agree that it isn't appropriate to show disrespect for those who have been killed in tragic accidents. I also recognize that flying airplanes that we build is an inherently risky activity. No one wants to loose friends, but we loose them. My own mother died in a automobile accident when I was young. It happens, and yes we want to try to avoid them and learn from them, but they
still happen.
I don't think Mike intended any disrespect but (perhaps untactfully) was trying to make a point. I think what he was trying to say is that we need to be careful and be thinking about what we are doing, or it may kill us. I took it in a tongue-in-cheek sort of way in that he is reminding me to carefully evaluate my decisions so I don't do something that would hurt me or someone else.
Peter Zaccagnino said it best when he said "I have to remember that these things are trying to kill me."
When we try to avoid negative aspects of design it is too easy to come up with dumb solutions like plastic gas cans with those impossible to open spouts. I have spilled more gasoline trying to use those dang things than with the old metal flexing open spouts. My point is that it can be easy to over design something.
On the pilot side of a Cessna 172 Hawker XP (perhaps on others as well) there is this really dumb seat latch. You have to not only hold up the level than allows the seat to slide, but you also have to reach behind you and use your thumb to open a secondary latch. It appears this was added perhaps after a seat unintentionally slid back and was a factor in an accident. It smells like a lawyer designed it.
Can you imagine being in an accident and having to work both latches to get out of the airplane? This is what happens when we try to take the risk out of everything and place walls of protection around us. Pretty soon they have either hurt us or make it so we can't do what we originally intended.
I really like the current canopy design. It opens easily. I really like this feature, I feel safer because
of it.
Thanks
Kevin

Subject: [LML] Re: Legacy Canopy Problem
Do you mean that the people who have had a canopy open are somehow inferior and wlll be naturally removed because they aren't cut out to be pilots? Is that the meaning of your message? Or is that a canopy that can be opened is a way of selecting better pilots in this world. Please explain your Darwin comment to us. I really want to know how that works into the problem here.

PS: for the dolts who can't figure it out, there's another mode of canopy opening that won't be solved with a checklist on the ground. Think outside the cabin should be the first rule on this subject.

Pre-takeoff checklist
Trim, fuel selector, mixture, prop, push up (hard) on the canopy. (five plus one)
This isn't a big deal to me. I don't think drama surrounding the canopy is needed or deserved.
It has been shown that while tricky, the airplane is controllable if you happen to leave the canopy open. Just don't stop flying the airplane. Better yet, don't leave it unlocked.
