Hunter, I inferred, perhaps incorrectly, that the pilot's remark "we have lost the speeds" was a response to an indication failure of his airspeed indicator, which I presume, also perhaps incorrectly, would be something like an "off flag" or "red X" or other marked change in presentation.
It may have seemed far too obvious a detail for the BEA to dwell on?
If I am off the mark here, please advise.
