Interesting in that I have seen a sudden loss of airspeed on a couple of occasions. If I hadn't pitched down immediately & got the airspeed increasing. Well you would be reading about it on here. Jet streams & surprise CAT are not uncommon so IMHO get the nose down so you know your airspeed will be increasing & then asses, confirm the situation & act appropriately. To ignor seems to be an odd thing to do.
Well I guess Boeing suspect pilots can no longer fly so will end up crashing anyway.
