High wined aircraft usually have two doors, low winged ones have one,

Mine doesn't have any doors. Or one big clear one wrapped
around the top, depending on how you look at it.

Paul, as much as I like your concept, probably 10 or 20% of the time I climb
into my airplane it's raining. I have enough problem trying to keep the
passanger seat dry with a single door. I think your one big clear one would be
great for recreational flying, but the good news for me is, most of my time
gets paid for out of a corporate pocket, not my own, so utility in not so nice
conditions becomes important.
