I assume that you mean smooth vs. rough.
I have had a lot of smooth landings, I don't remember any one in particular.
The most frightening landing that I can recall was an MU
737-300 from PEK
-LHW. I don't recall any problems on approach. Right when we hit the ground, we swerved hard to the right. Everyone screamed, but the pilot recovered. I still have no idea what happened. It was the only time that I have thought that I might not make it.
In one month, I will be flying SXM
, which should be an interesting landing.
