Very cool picture and easily possible with a decent length exposure. I took a similar picture with my digital camera out shooting an eclipse of the moon. I saw a small plane coming over and so I quickly turned around the camera to try it out. The steady lights do appear as streaks, however because strobes and beacons are only on for a very short period they appear as dots in the final image. Lots of fun doing exposure shots....make yourself appear as a ghost in a fully lit room by running in front of the camera, stopping for a moment, and running out the other side!
