Do water landings for non seaplanes seem rather abrupt?
« on: May 06, 2024, 08:01:17 AM »

When non seaplanes are forced to land on water it seems to me that they come to a stop rather abruptly. The final contact with the water (if there has been a bounce prior) has the plane stop in a distance not much longer than a fuselage length or two. Hard stops like that should be expected to tear off a piece or two, such as low-slung engines. If the plane is to remain intact (as it always seems to), wouldn't a somewhat less severe deceleration be more appropriate?

That clip certainly serves nicely; thanks!

After the first skip, during which the velocity had not been retarded too appreciably, for the second contact the downward pitch angle certainly resulted in more 'digging' and a stoppage within about two plane lengths.

Another example. A very abrupt landing indeed, with consequences.


I think there are so many variables, not just a mass-speed-angle, but also the shape of the lower fuselage plays a significant role. And a mass distribution: tail heavy or nose heavy, etc. And then the sea condition: wave height/length and direction.

By the way, it is interesting to see how B-24 connects with water, almost like a flying boat. More graceful than B-29.

And the famous one. It's a poor quality, but it gives an idea.
