AF447 crash may have similarities to Aeroperu flight 603. Both had Loss of vital instruments during flight and subsequent loss of control. Both AC were lost over water at night. Both AC had false warnings.
The difference is that AF447 was not in radio contact with anyone and was in bad weather. Would a study of Aeroperu flight 603 be worth consideration?
I'm not saying someone covered AF447's instrument probes with tape, but the end results of these two accidents seem to have some similarities.....
