Narrative: Captain and I each received a phone call from company Dispatch for an ASAP trip. As usual; we rushed to gather personal belongings; check out from hotel; call a cab; drive to airport; review flight plan; weather; etc.; on our smart phones while in the cab. At the airport; the Captain goes on to pay for FBO fees while I preflight aircraft; got ATC clearance; and set up GPS/Avionics (this time; however; we decided to depart VFR in VMC conditions because I was not able to make radio contact with ATC on the ground). As we began taxing; I made my first radio call on CTAF from the ramp. Our taxi was hectic as we carried out departure briefing and routine taxi checks. Some chatter was heard on radio; but we did not think much of it. We arrived at the hold short line of approach end of Runway 5. I made another radio call to take the runway for departure. As we taxied onto Runway 5; we visually checked final approach and runway for traffic and did not see any traffic. As we momentarily held position on runway for power adjustment and systems scan; a twin Baron announced on radio he was still on the runway. Captain and I look at each other in complete disbelief. I immediately got on radio. I do not recall exactly what I said but it was something along the lines of 'we are on Runway 5...what is your location? ...say intentions.' As I communicated with the Baron pilot; the Captain was turning the airplane away from the runway and back to the taxiway. The pilot says on the radio; very calmly and professionally; that we can hold position on the runway and do not need to move...he was just completing his landing roll on Runway 23 and will be clear momentarily. We must have been some 4;000 FT apart. Both ends of Runway 5/23 are lower than the center point of the runway and we could not see the Baron from the opposite end of the runway. I do not recall if we actually made it off the runway completely but went on to takeoff a minute or two later after the Baron exited the runway. The Baron had become visible to us as it made a turn on a taxiway. Ultimately; the Captain and I had a conversation after that flight. We believe; due to the on-demand nature of our work; as a crew; we have to operate under immense pressures to get in the air quickly. For the majority of our flying occurs during night hours; we can become complacent about slow traffic at non-towered airports. If we had exercised more vigilance outside the cockpit; we could have become aware sooner that a Baron was in the vicinity and would have never entered Runway 5 when we did.




Synopsis: Turboprop First Officer reports announcing intentions to depart Runway 5 at AND airport then learned that a Baron is rolling out opposite direction.
