(9) At 02:12:02, several thousand feet below FL350, does the PF's comment that he had no more indications indicate that his ASI reading had only just dropped to a value that he no longer believed? Is it remotely possible that, perhaps unlike the others, the drain hole of his pitot tube had blocked at the same time as the intake? During the initial climb, could he have thought that his ASI was still valid, and that he was trying to avoid an overspeed? [See (6) & (7), above.]

PNF "...we've lost the speeds" "...alternate law"
No acknowledgement from PF.

02:12:02
PF "I don't have any more indications"
PNF "We have no valid indications"
First sign of PF identifying problem with indications.
PNF acknowledges.
