Narrative:

As we were taxiing for takeoff in homer; ak; we cleared the runway clear right/left. I made a radio call stating we were departing runway 3. Another aircraft came on the radio and said he was on short final for runway 21; on the captain's side. We immediately came to a stop short of the runway and not across the hold line. While we were waiting for the taildragger (I believe it was a champ); I pointed out to the captain a cessna turning base for runway 3. As the champ was rolling out on runway 21; the captain started taxiing onto the runway for departure. I told him the plane was still rolling out on runway 21 and the other aircraft was turning final for runway 3. He said it wasn't going to be a problem and made a radio call. Homer radio came on the radio and said there was a plane still on runway 21. The captain said 'I think he is turning off on taxiway a.' the cessna for runway 3 ended up going around and re-entering downwind for runway 3. This situation was very dangerous and we never should have taxied onto the runway. After this happened; I realized that I really should've used the brakes and stopped the plane from taxiing onto the runway. The captain had the attitude that we are an airline and the other planes should let us be the first to depart.
