NR Fairy, you jinxed me!
Today flying one of our 500's my door popped open, couldnt get it shut , was the top forward latch. Of course the weather was just beauitful, and there was no wind either!

coulnd have happened on a nicer day..... just my luck
ended up landing, slamming her and back to proper business of punching holes in the fog, rain and a blowing westerly
