J3 Cub (3 Counties at Blackbushe), 1969. As far as I recall £4 10s solo and £5 10s instructional. My conversion gliding Silver C to PPL(A) licence cost me £37 5s in flying fees, as soon as my brown licence arrived from the friendly CAA I was flying an RF4 at around £4 per hour.
On the other hand, my annual salary was about half my monthly one now.
