Narrative:

After crew loaded aircraft, a passenger opened the cargo door and put an additional bag on board. The crew had already secured the doors up front and was in the process of securing the rear cargo area. The aircraft was taxied out to the runway and en route got a cargo door unlock light for 15 seconds then it went out. Takeoff was performed and at approximately 50 ft the left cargo door came unlatched and a bag fell out. The aircraft was flown to an immediate left downwind and landed on the takeoff runway without incident. The crew inspected the aircraft for damage and found none. An airport security vehicle recovered the bag on the runway. Another bag landed off airport. No civil damage. Cause of event was failure of the captain (me) to do a walkaround inspection of the aircraft to assure all baggage doors were secured. Other factor is allowing passenger to load baggage. This is now a no-no in our operations SOP -- only the crew is allowed to load baggage and open/secure baggage doors.
