I think that you are being unjust Iain. Most SLF are able to recognise a bone-shattering arrival when they experience it.
To answer your question pcascio; All airlines have very strict rules about the reporting, and subsequent actions after a heavy landing. The maintenance action will depend on the aircraft type and the severity of the impact, and varies between a visual inspection to a complete structural integrity check including removing appropriate panels. Different aircraft types have different maximum 'g' limits which generally are between 1.6g and 2.0g.
Most modern aircraft have an system called ACMS, which will automatically send a report to the maintenance HQ of the airline. It will also give a printout of the 'g' readings if the maximum levels were exceded. The heavy landing will also be recorded on the CMC (Central Maintenance Computer) so there is no point in trying to deny it.
I'm sure that the crew in your case would have taken the appropriate action as it is in their interest as well as yours to ensure that the aircraft has been checked.
Hope this helps
