90% true + 10% false
Reading Langewiesche - supposed expert "human factors" - in Vanity Fair in October 2014 and the Airliners.net forum commenting on the same ... vulgar article ... shows that the forum PPRuNe is still better than that of Airliners.net !
I am appalled that a "specialist" human factors as Langewiesche could write so much against facts. The manipulators write beautiful texts, with 90% true and 10% false.
