If I recall corectly, I had an hour on a PA-22, 1:45 in the coal-hole of a Sea Vixen, another hour in an Auster and a couple of trips in a Tiger Moth before I did my PPL.
Did I log them? They were all air experience flights and, apart from the Sea Vixen trip, I had a go at the controls on each trip. But to consider them as 'hours building' non-P1 sense hours? Of course not - I was merely a lucky passenger.
