In my time on the Seaking we used to practise double comp freeze with the engines in manual as a single pilot - testing but no real drama if you followed the SOPs. I believe the Fisheads used to fly the MK4 Commando single pilot - so if they could do it it can't be that difficult
Well done to Flt Lt Wales - Valley is one of the more demanding flights to be on - second only to Lossie of course!!
