411A is a LONG-RETIRED, former airline pilot (questionable) who lives in front of his PC. He gets his rocks off by tormenting anyone who'll respond to his drivel. It's the credibility he so desperately needs, the recognition he no longer has.
His frame of reference is an obsolete type (L1011) that was brilliant in the 80's but becoming more of a museum piece by the day. The moment the conversation turns to modern aircraft types, his vitriol against GLASS and AIRBOOS picks up, even although he's never flown either. He understands neither.
He can say ANYTHING, claim to be ANYONE, all under the shield of anonymity the Internet affords lurking cretins.
If he bothers you, ignore him. It will upset him more than anything if no-one responds to his claptrap.
It's liberating and empowering to put him on your ignore list.
His identity is dead easy to discover, if you wish to - but DON'T. He'll revel in the attention. It's what he wants.
He NEEDS attention, just like The Guvnor did.
