A successful ditching, with no distress beacons, on a moonless night? In an aircraft not able to continue on its way or head for an airfield?
Doesn't sound very likely.
While you'd want to aviate first, if you were going into the sea, having a word with someone might help, at least to let them know what time you were going into the sea, so they could use a piece of string and a ruler to come and find the debris afterwards.
