When watching the video, and looking out the window, the sea is calm, almost glass like in appearance, accounting for the smooth landing as it were. Large swells would have likely caused grave damage to both aircraft and occupants, due to the blunt forces. Skimming versus colliding. Two very different variants.
Agree w you. My sister is an Air Traffic Control Supervisor. She is not so sanguine about sea landing/crashes as some. Particularly w planes that have no retractable landing gear. Waves can wreak havoc w fixed/extended landing gear. Bottom line, I wd not agree to be a passenger on a Cessna that was scheduled to crash-land in the sea. Wdn’t care for my odds at all.
