To be honest, cracked mirrors blamed on "poor pilot landing techniques" does seem pretty farcical and more like an introduction to some sort of joke or wind up. Can't see anyone saying this.
I HOPE it's not true. I mean, could you imagine an airline exec being so dense as to say such a thing ? Effectively saying "our guys prang them in so hard they're breaking the mirrors and fragile stuff in the jet."
I guess it's ONE form of expectation management of sorts. "Well, THAT wasn't so bad."
Normally the boasts go the other way--with sometimes poor results in that the Aviation gods do abhor arrogance and tend to teach humility.
