...roughest landing I ever had was in I Mexico city about 25 years ago.
Mexicana Air.... thought the landing gear was gonna come up through the floor...very hard
The scariest landing I experienced was at SFO. The airport had been closed by high winds for hours. Even the Golden Gate Bridge had been closed.
When my older model 737 entered final approach, it became evident that winds were still high and turbulent. Aircraft was bouncing and rolling. What scared me was when it began to yaw, as well. Landed safely, even though rough and bouncy.
After parking at the gate, as the stews walked up the isle, I overheard the boss tell the others that during final approach the captain had told her to prepare to ditch.
