Yes. there is a silence. Iberia has a good reputation regarding safety and good airmanship. No body wants to blame a 340 crew with a high level of experience just because a pilot who nobody knows put a post in PPRuNe. I think every body could speak about things we do not like in day to day operation from other airliners and we do not post every thing we see.
This does not seem to be trying to improve safety but just a kind of blame that this pilot should do "face to face" with that captain and not hiding his face in this forum.
Regards.
