Closing the door on a Cirrus in flight

Incidentally, it was not my son who had played with the window that caused
it to pop (he is not the type), but rather a mechanic who had worked on my
aircraft the previous day and had opened the window for cooling, but failed
to slam it closed for the lock to catch. I then concluded that this was a
previously undetected weak point in my preflight checklist.

Nice fairly uneventful way to find a new checklist item!
