Die Lösung ist verblüffend

[Jens Holzkämper]

Tach,

Das spricht gegen die Dokumentation bzw. deren Autoren. Notwassern ist zwar nicht tägliche Routine, aber doch immerhin eine mehr oder weniger übliche Methode, ein Flugzeug "runter zu bekommen". Sowas sollte in der Sammlung der Checklisten durchaus schnell zu finden sein.

selbst wenn es schnell zu finden wäre, der gesamte Flug dauerte von Start bis zur Notwasserung 6 Minuten, die ersten 2 davon war alles gut. Vom Ausfall der Triebwerke bis zum Aufsetzen waren also etwa 4 Minuten Zeit in denen der Copilot sicher auch noch anderes getan hat, als nur Checklisten zu lesen.

Und der Captain sieht das ähnlich:
"Air & Space: So your first officer would have found that procedure and had a checklist to go through for the ditching procedure?

Sullenberger: Not in this case. Time would not allow it. The higher priority procedure to follow was for the loss of both engines. The ditching would have been far secondary to that. Not only did we not have time to go through a ditching checklist, we didn’t have time to even finish the checklist for loss of thrust in both engines. That was a three-page checklist, and we didn’t even have time to finish the first page. That’s how time-compressed this was." - http://www.airspacemag.com/flight-today/Sullys-Tale.html

Vom Wasserdicht-Knopf hält er übrigens immer noch nichts:
"Air & Space: Did the airplane have a ditch button that would have sealed certain openings in the cabin?

Sullenberger: Yes, it’s called a ditching push button. And there was not time. We never got to the ditching push button on the checklist. It wouldn’t have mattered anyway. The vents that are normally open are small. And once the airplane touched the water, the contact opened holes in the bottom of the airplane much, much larger than all of the vents that this ditching push button was designed to close.
I cannot conceive of any ditching or water landing where it would help. Theoretically I understand why the engineers included it. It sounded like a good idea, but not in practice. We had a successful water landing, and even then, from seeing pictures of [the airplane] being removed from the river by a crane, there were much larger holes than the vents this button was designed to close." - s.o.
