The Nr Fairy:
A 'perfect touchdown' is seldom the aim. To meet performance criteria you must be at the right speed, the right place at the right pitch attitude and 'G' loading.
Very smooth touchdowns sometimes arise due to excessive speed or too high pitch attitude. A wet runway requires a firm touchdown, for example, to prevent aquaplaning.
Autoland systems provide for a 'firm' touchdown.
It is nice to be appreciated though.
