I listened to CNN's Richard Quest (supposed expert) and he contradicted himself during the broadcast, he showed the sequence with him in the cockpit with the FO while flying (how does Richard get permission to site in the cockpit during the flight) and he said he was an experienced FO, less that a minute later he called him an inexperienced FO. Richard needs a good does of realism and not trying to look pretty spouting off inaccuracy's about pilots and aircraft - just (English)drivel
In the segment I watched he said the FO was experienced but new to the 777.
