I live near a major airport and see commercial planes with huge front headlights shining in the night sky. What could they be good for way up in the sky, though? I get that when they are taking off/landing headlights are necessary. Why not give them lights like a boat, with a green in front and a red in back?
Ha, I was going to comment on this.
Boats are also supposed to have white lights at the stern and (if they have one) at the top of the mast.
