Hi,
I am sorry but this is now becoming stupid. Reading some comments here you would think aviation safety has just taken a nose dive.
The fact is that the aviation safety will (or be feel) taking a nose dive .. when pilots are not good enough for cope with emergency situations.
In the case of AF477 .. my feeling is that the pilots were maybe good .. but not good enough for cope with a unusual ? (the UAS is not a new event BTW) situation
