Thanks Snakecharma. We've had several instances of 'firm' landings that weren't reported at the time but were subsequently determined to be 'hard' when the data was analysed. We've had it drummed into us that if there's any doubt it should written up as a hard landing and investigated accordingly. Mind you - I work for a big international airline wih engineering resources at every port, so it's relatively easy to complete the initial inspection of the aircraft. Not sure if the same applies to Virgin's operation at Apia.
