Flew fires IA with 212/412 that had those stick-on convex mirrors on the inside of the door. Land, open the door, then reference the mirror to place the skids on that rear log. Also helped to see how far down you were sinking into the bog.
Had a log Jill-poke up between the belly tank and the skid once - held the hover until a savvy firefighter chainsawed it outta there. Mirrors help.
