Cirri are somewhat notorious for not having one of their two door
latches pop open in flight (usually because they weren't properly
latched on the ground). I have often wondered if it might be possible
to correct the problem in flight by popping the other latch, opening the
door, and slamming it shut. But I've always been leery of actually
trying it and finding out.

Well, today I was presented with the opportunity of doing this
experiment when I actually forgot to close the pilot-side door before
taking off. (Don't ask.) I am somewhat disappointed to report that,
no, there is absolutely no way to close the door of a Cirrus while
flying. You have to land.

Just in case anyone else was wondering.

P.S. I can also report that the Bose Headset X is really quite superb
at canceling out the sound of air rushing in through an open door on a
Cirrus. I was at nearly 1000 AGL wondering why my climb performance
sucked so badly before I figured out what was going on.
