Here we go...ATC audio:
http://abcnews.go.com/US/video/mayday-call-passenger-falls-plane-20893799

Passenger fell from the aircraft about eight miles southeast of Tamiami Airport, about one mile offshore at around 1:30 p.m The plane flew on to Tamiami Airport and landed safely, the FAA said. In the mayday call to air traffic controllers posted on the website LiveATC.net, the pilot said: "I have a door ajar, and a passenger that fell down. I am six miles from Tamiami." A little later in the exchange, the air traffic controller asks: "So you said you had a passenger who fell out of your plane?" That is correct, sir. He opened the back door, and he just fall down the plane," the pilot said.

I once owned a B58 Baron which had a front passenger - it popped open in flight. I can tell you that it trailed about 4" open and was virtually impossible to close in flight, even at stall speed with a slip to the right. Conversely it was also virtually impossible to open into the wind stream.

My best guess is that this had to be an intentional act.

Lots of PA-46 versions. The picture looks like a piston version which could be either pressurized or not. If pressurized, the door can not be easily opened. The door also has a top and bottom half that have independent latches that must be operated to open with the top one being first. You cannot really accidentally fall out. You would have to make the conscience effort to either fit yourself through the top half of the door or take the further step of opening the bottom half to jump out. At 2000' even a pressurized version wouldn't have enough differential to blow you out if either door latch failed. Bottom line, suicide, homicide, or made up story.

I guess if you drink enough Malibu, you could fall out of one...

It is either George Bush's fault or that Evil Marijuana

Would be interesting ATC audio. I read the initial report was an "open door" and on a second call he declared an emergency and stated someone fell out of the plane.

don't understand, I own an airplane with the same door configuration and there is no "ajar" it is either open or closed and if the guy fell than it was open. It also seems like his call to atc was not obscured by wind noise as would be expected. I think the may day call should have focused on the guy that "fell" and not the door "ajar" open. I question if the passenger was ever on board.

“He opened the back door and he just fall down the plane,” the pilot said, according a recording of his conversation with air traffic controllers.

The pilot reported that he was flying at 1,800 feet six miles from Kendall-Tamiami Executive Airport when the man fell on Thursday afternoon, officials said.

Questions????? Air pressure against the door? Seat Belt? Tail Number? Where did the pilot land? Interview of the pilot? There is so much missing in this report.

Body found in mangrove presumed to be that of passenger who fell from plane...not out at sea. Hmmmm?

Any news about the fallen angel ?

One other tidbit!!! Tamiami is more then 6nm inland!!!!!
Just my $.02

Uhhhhhh........ SOOOOOOO crazy I'm gonna go out on a limb and suggest 'cover up' for an 'intentional act'?

Evidence would be well ruined (if found) but you'd make yourself forever venerable to police scrutiny.

Or a nutty 'prank call'???? Dumb cuz you're busted.

Who knows? (Yet)

Ooops...
