Rapid Command ?
As far as i read on their site rapid command means 5000 hrs ( F/O or CMD) on planes above 55 tonnes and then a certain time with them (1 year or more). As far as I found out they only consider F/O s with 777 ratings and a minimum of 1000-1500 hours for rapid command.
And their application site is (or will be open soon) again for applications , but only for F/O as they have enough DEC s.
