A previous post on this topic referrred to the CVR being not usable because of the duration of the flight (report from newspaper - yes,I know how inacurate the general press is on aviation matters). Does anyone know:
(1) whether this 340 had a digital CVR, and what are it's characteristics
(2) I have heard of enhancements of tape loops to retrieve previous data (back 5-6-7 loops as I recall). Anyone have info on this capability?
