Ark, another top wheeze when putting a LHS pilot into a UP during IF training was to have the door open and put your finger over the end of the pitot. When you gave him control he would keep pushing the nose down to try and gain speed until you removed your finger and gave him an instant 100 kts IAS and a completely different UP to recover from.. .Lu, if you want to see an S58 twin pack flying the go to New York, they were still doing airport transfers and sightseeing trips in one a few years ago.
