They dont take no FO"s on the 777s they only take em on the 743s. If however you do land up then take a cue from the pedros and the cossacks. ie keep your gob shut, dont even try to change anything,dont compare it to anything else and believe you me you will love it. Just take it day by day fly when they tell you to do yer 3 weeks on take yer money home to yer family and enjoy yer 1 week off. SIMPLE
