My first flight 61 years ago, in a Hunting Clan Vickers Viking from Malta to London with a refuelling stop at Nice. Over Northern France I was invited up to the cockpit & was handed over control. As an 11 year old school boy my feet wouldn't reach the rudder pedals, so we did a kind of yaw to the left then right.
First RAF flight Two years later at a CCF summer camp at RAF Gutersloh in a Percival Prentice.
First Jet flight at RAF Debden in a Meteor 11, which had just completed a Major Service - Yes, sick as a dog!!
Most memorable flights doing Radar flight trials at RAF Marham with 57 Sqn. in HP Victor K1 Tankers
