Ok, but what about landing?

There is often wind at the surface during landing as well. If the wind is
significant, the pilot must adjust for it as he lands the aircraft (most
landings are done manually by the pilot, although many modern airliners can
land themselves if the pilot configures them to do so). If the wind is
steady, the pilot applies a constant correction to keep the aircraft aligned
with the runway. If it is gusting, he may have to constantly adjust the
controls to maintain alignment. You would see this as continual changes in
attitude, with slight rolling to one side or the other (the aircraft must roll
in order to turn).

The landing runway wasn't in the same
direction of the rest of the flight, so the wind probably was blowing
in a different direction.

Winds often blow in different directions at different altitudes, including at
the surface, so the correction applied must change as the altitude changes.

My sensation was that, at the moment of landing, the pilot was really
not able to have a good trim due to a decise clockwise roll, that he
was really not able to correct with the normal actions, despite of
various tentatives.

The sensations are often stronger than the actual corrections applied. Most
airliners are flown in an exceedingly docile way, which gives no hint of the
maneuvers that they can safely undertake. If the pilot had to make greater
than usual corrections, this could easily give the impression that the
aircraft is moving dramatically, even though it is not. It's moving more than
it normally does, but it is not moving in any unsafe way. It's just that
normal flight is so gentle (deliberately so, since this helps ensure the
comfort of passengers) that any departure from this seems extreme in
comparison.

The impression was like that the right engine was
not enough "powerful", or the airplane was heavier on the right side.
Of course, impressions of a not-expert people.

The engines are more than powerful enough to ensure safe flight. Pilots are
able to land a twin-engine aircraft with just one engine, and aircraft with
more than two engines are even easier to land with an engine out. However,
engines almost never fail (most airline pilots will go through their entire
careers without experiencing an engine failure), so it's unlikely that an
engine problem occurred in this case.

But since I had a large number of flights in my life and I know what
happens in case of lateral wind, also during landing, I repeat that my
sensation was not of lateral wind.

You can't feel a lateral wind. You can only feel corrections made for it, and
sometimes not even that. Without being in the cockpit and seeing the
instruments, it can be difficult to determine just how the aircraft is moving,
from the viewpoint of a passenger with only a small window on one side of the
plane.

Ok, thank you: I was really calm during the flight, only after landing
I was wondering about what has happened and I was curious about that.

Do you have a fear of flying? People who become concerned about a few
centimeters of movement in a wingtip or who interpret unusual experiences as
possible engine failures often do.
