What carriers? It's been a long time since I've experienced rough landings or even as much TATL/TPAC turbulence as I recall in the past. I assumed that instrumentation has gotten much better.

However, I do sometimes notice (exUSA and certain other countries) major airport flights where I have the impression that the pilot wants to gain altitude as fast as possible and I sometimes wonder whether there's some perceived risk from shoulder fired misses and similar threats to cause this. I first noticed it when flying shortly after 9/11.
