In light of today's accident in New York, I was thinking about escape and floatation equipment. I can understand how life vests and detachable slide rafts work. But I'm confused about how one could use rafts that are kept in overhead compartments.

The scenario would be as follows: the plane is falling from the sky, about to hit water. You have to find the raft, get it out of the compartment, get it out the window, inflate it, then get in it. It seems somewhat implausible.

Can anyone comment on this?

Quoting Mats (Thread starter):

Mats, you pretty much answered your own question. The alternative to this is automatic deployment, which is not only costly to own but costly to maintain.

The manufacturers have instead focus on producing aircraft that can meet FAA (and other) standards for minimum time afloat, etc. vs. rapid release items. Ditching is quite literally the last of last options when it comes to landing, and is usually done as a forced option (no land in range) or a forced-choice option (water ditching is safer than attempting a small field or road landing in a metropolitan area).

You don't get the raft out of the bin until after you've stopped. Then you pitch the bundle through an open exit, and yank the lanyard. At 6:58 in the following, a small raft is being inflated:
