But I guess there are quite a number of Air Nelson F/O ready and keen for a command upgrade.
I would be surprised if the AOC holders risk mitigation tool spat out a result of " very low risk" when the input was ' lets hire first officers and upgrade them to Captain at the recruitment stage'.
With that in mind I'd wager that all of the Captains recruited will have previously held part 121 commands and most probably on the Dash.
