Just to clearify a few things, the crew didn't know there was a tail strike, however, due to late lift off, the crew suspected the gear might have damaged some runway lighting or equipment, hence asked ANC to check the runway. ANC replied that no damage nor debris were found.
The feeling of a tail strike depends on the magnitude of which, a lighter one can not be felt, this one felt exactly the same as a landing (thus crew suspected a second wheel contact), the damage so far is only a few panel replacement. Not sure what it felt like on SQ flight in AKL 2003.
By the way, does anyone know what happened to the crew on SQ and CX flights that had tail strike in AKL?
