Had it happens many years ago on the cabin door of a 206B, with pax in the back. Caused great excitement amongst the pax, particularly because of the explosive burst of sound from rushing air that accompanied the actual opening. Rather than trying to brief already excited pax on what to do next (the pre-departure brief told them how to open the door, not to close it in flight!) I just aimed it into the nearest field and sorted it on the ground.
Also had a caption on a 109E one time because the upper pin on the pilot's side cockpit door hadn't gone properly home while closing it on the ground. Shortly after take-off, the buffetting got enough to pull the door out a little at the top, enought to activate the switch and give me a caption.
I just left the controls alone, the aircraft was already established in the cimb-out and the Force Trim held them just where they were, and proceeded to release the door with a view to closing it properly.
However, even passing 40kts, once the door was actually open, even just a little bit, it caused an awesome racket, was extremely difficult to get closed and I thought "Right, I won't be doing that again!!"
It's such a tragedy the pilot didn't just leave it and get it down first, particularly as a colleague had the same or a similar problem and was able to bring the aircraft to the hover without incident.
