With all due respect Lyman, that's a poor excuse.
Several UAS incidents in the A330/340 preceded this one and none of them ended up in the drink, because in all cases the crew figured out what was going on and either applied the correct procedure or improvised one of their own to get them out of trouble.
If the design was so faulty as to take the crew out of the loop in every case then we'd be looking at more than one fatal incident due to LOC following UAS in an A330.
