An earlier post alluded to temp commands at bmi baby - I'm certain these did not occur but we did have some contract captains for a while.
Coincidentally, I flew with another captain last night, both of us commented that we felt mildly disorientated whilst acting as PNF in the RHS. A quick RHS check in the sim every 6 months doesn't adequately prepare you for a full day in the wrong seat.
