I saw a piece on the the DC10. Apparently, the hardware for an outer cargo hold door would warp when trying to seal
the door if it wasn't really secured, sending a false signal that the door wasn't a jar.

So, the plane might depressurized suddenly, collapsing the passenger floor...

The end of it was once the hardware was replaced, (automatic vents for the floor, too) it was too late for the
passenger days of the DC10.

They are now an efficient cargo transporter, though.

The end of the DC-10 in passenger service had nothing to do with the cargo door problems. The aircraft simply reached the end of its service life and coupled with their higher fuel burn made them uneconomical to operate as passenger aircraft.

However, you can still find DC-10's flying passengers including with Northwest Airlines. Although this is true for only a few more months as the last DC-10's are heading out of the fleet fairly soon.
