Mostly fun to fly, especially the Tutor - wonderfully light & maneuverable - great for aerobatics. 'Steam driven' instruments & technology of the time - no auto pilot assist.
Then I had a great tour on the CF 101B Voodoo Interceptor:
A challenging Century Series aircraft designed in the late 1940s. Inadequate tube computers with some auto pilot assist. Nice & powerful (dual afterburners in winter temps was a joy) but very unforgiving that made flying it and adventure - high landing speed (175 - 225 Kts). Check out the phenomena of 'pitch up' on the net.
Really powerful, fully computerized so easy to fly (computers do most of the work) - enough so that I was able to land it from the back seat without incident, ha!
Since I was already challenged enough, especially flying SAR missions in the Labrador all by hand mostly in adverse conditions (weather, night, mountains, out to sea, etc), I would choose new technology found in the latest helos to enhance getting the job done any day.
I am thankful though that I had an opportunity to fly some pretty cool & powerful machines in my day...
