Narrative:

Cabin door came open at approximately 300 ft AGL on takeoff from kissimmee airport (ism). Emergency was declared and radar vectors were secured from orlando approach control for a landing at mco. This event occurred at night, in the rain. The door went to the full open position and remained there for the duration of the flight. Total flight time was 8 mins. The open door caused tremendous wind noise and made communications between the crew and with the ground very difficult. Additionally, several pieces of paper left the flight deck. Anything not secured may become unavailable in an instant. The departure and emergency return procedures had been thoroughly briefed and that helped under difficult communication circumstances. Crew coordination during this event was aided by the fact that we train together in the simulator and have specific company procedures. Although incidents such as this are extremely rare, you cannot be overprepared for such an event. I would urge all flcs to look, then look again, at what they can do to better prepare for an emergency situation.
