As Dogma says ETOPS on the 737 by skippers with no previous jet time , never mind oceanic or ETOPS exp' with cadets who pay for the privellege in the RHS , no thanks !
There is at least one capt there whose previous experience is entirely on a turbo prop and was never much of a star on that by all accounts , few months in GSM , now a skipper on the NOrth Atlantic with winter approaching ! mind blowing!
