The Tower [was] closed. Our plan was to make six touch and goes on Runway 35L. A Remos small plane had started before the Tower closed and was using Runway 35L. He was talking when we synced our go around with his; then he landed and went to parking (but was still 'talking' on the radio). [There was] also; a helicopter four miles northeast [they were] 'talking' but was not going to land. There may have been a 4th voice; but it was low; quiet and nobody understood who he was or what he was doing.We were announcing 'downwind' left base for Runway 35L when another airplane appeared to takeoff on Runway 17R and quickly turned right under our DA-40 as we were turning final. We could see a red position light as he turned but no landing or white lights. He missed us by about 250 FT and obviously could see us as we had our strobes; landing and taxi lights on. There were green and red 'row' lights showing Runway 35L was preferred. ASOS report 240 degrees/3. He took off on Runway 17. Pretty scary.
A DA-40 private pilot just turning final to land on Runway 35L at HND suffered an NMAC with another unidentified aircraft taking off the opposite direction. The Tower was closed and CTAF communications were muddled.
