Dear ABL,
You really know how to make a chap feel old! When I started flying with UBAS, the first flight of the Bulldog prototype (1969) was two years away and it was eight years until Bulldogs replaced Chipmunks!
You can make me feel better by giving me a ride next time I'm in California.
PS Looking at your group photo, do I detect eight instructors? That seems like a lot. How many aircraft and how many students?
