I have a book on the Convair CV880 and CV990, and it shows a picture on one of the pages of an 880 that was converted for cargo-carrying, landing at an airport with the cargo door open. Caption says: Photographer Larry Ivan Potoski was down to his last frame on Sept. 22, 1979 when the unbelievable appeared in his view finder. Monarch's N8816E was returning to Miami International with its cargo door fully open, proving how good the door hinges really were. This turned out to be number 38 on a 36-exposure roll of flim.
Basically, what must have happened to the DC-8 and the Convair is that the cargo door was not properly latched, and swung open on its own. The lack of total pressurisation at sea level vs. cruising altitude would allow the door to open outward if not properly latched. Thankfully, there were no severe consequences to either the CV880 I mentioned or the DC-8 in the photo.

Yes, things like this have happened. Several AD's have been written to prevent occurances. The worst case of this was on a DC-9-33F (I believe at Ellington AFB before it was deactivated, near Houston,TX). The airplane went inverted; needless to say, the results were not good.

When I worked at FIne Air my buddy had a cargo door open up on him also.
The deal with the door is such.... When the cam locks rotate sometimes they grab the bottom of the bar instead of rotating around it.
The locking pins engage which is one of the things checked when the door is closed. The locking pins will appear to have been closed.
The door when improperly latched will give a secure indication on the safety pins.
The door light will also extinguish as the contact will have been made.
My friend was an excellent engineer and stated he was absolutley positive that he visually checked both. There's no doubt that's what he did.
Upon rotation the fuselage flexes, and the door pops open.
He heard a loud pop, and heard a lot of wind noise. Not sure weather going back there to make an inspection would have been a good idea the captain elected to make an immediate return to the airport. Upon arrival the crew called the tower and said someone blew some plane parts all over the runway unaware it ewas them.
Upon pulling onto the ramp a huge croud had gathered and was gawking at the plane. My buddy still had no idea what had happened until walking out of the plane.

Yup, definitely real, see the FAA Incident Database System report number 19890714050329G. It was apparently a training flight. The door opened during rotation, the aircraft returned. The cause was not determined.
