This was part of my night training for my PPL in Paine Field, WA. Land on a runway with lights out and no landing light. It is important to use a long runway because you can use a floatplane glassy water technique. Pitch for the correct, nose-up attitude, set power to maintain a descent of about 150ft/min and wait for the landing. Very good job by the pilot!
In training I wasn't sure if I could do that in a real emergency... (Now as a floatplane pilot I think I could. Hopefully.)
