Quote from Doors to Automatic:
"By my calculations around 21 seconds to cover 6000ft, meaning 17,142 feet per minute, or around 1 million feet an hour. With 5280ft in a mile that gives an average ground speed of 194mph (169 kts) during the entire landing run.
The runway is actually very slightly longer so the speed was even higher.
It seems like a very high approach speed followed by virtually no deceleration."
Yes (until the end of the runway). Now why didn't I think of doing that? It certainly lends some support to the suggestion elsewhere that - following a very fast approach, possibly with limited flaps, the PF - realising there was insufficient distance remaining on a slippery surface - may have decided to go-around at or soon after touchdown. SOPs vary, but if - for example - the PNF is responsible for selecting the reverse on his own initiative after touchdown, as is (or at least used to be) the case in one large British airline, the PF can find himself faced with a fait-accompli. Any subsequent attempt to re-select forward thrust is likely to result in a grand cock-up...
One of the key points in the investigation will be how much fuel was remaining.
