I am not a RYR fanboy in any way, and there is a long list of issues about RYR that deserve to be discussed, but I don't think "hard landings" one of them. A landing can be perceived as "soft" if the runway is wet (or otherwise contaminated), and the wheels spin up more slowly. Similarly, hydroplaning could be felt as a very "smooth landing" (until the aircraft skids off the runway that is
). How "soft" or "hard" the landing is, is highly subjective, and while pilots will try take passengers subjective experience into account whenever possible, there are many important variables that need be considered to achieve a safe and successful landing. Sometimes, conditions call for a firm landing - well within the design limits of the aircraft (even though that may be marginally outside a particular toddlers subjective comfort zone). In summary, I think you're right, accusing RYR of "hard landings" is a non-issue.
